8 Ways to Clean Out Jewelry Clutter

I recommend looking through your jewelry once a year and pulling out pieces you no longer wear.  As a first step, take the time to clean the jewelry well; sometimes this will be enough to make you love it again (and if not, clean jewelry will help you with your next steps).  Consider why you don’t wear it, then take a look at the list below and take action. 

1. FIX it:
  For beaded jewelry, your local bead shop may have staff who offer repair services.  In addition, some bead shops have workshop hours when customers can do their own repairs using store tools and staff assistance.  I offer restringing services; contact me for more information. 

For gold, platinum, or silver jewelry, check with your local jewelry store.  Many stores offer on-site repairs  or send work out to a repair service.  Easy fixes include replacing clasps or re-soldering pieces together.  There is a “blue book” that provides guidance for pricing of jewelry repairs.  Not all jewelry stores use it, so be sure to get an estimate for any work you’d like done. 

Costume jewelry (plated or non-precious metals) may not be worth repairing unless it has strong sentimental value.

2. REDESIGN it:  Do you have heirloom or sentimental pieces that are not your style?  Jewelry that’s too long or too short?   Consider adding, replacing, or removing components to change the look to something you would enjoy wearing. A redesign may also offer the opportunity to make matching earrings or bracelets from leftover parts.  Again, your local bead shop or jewelry store would be a good place to start.  I am also happy to work with you to redesign beaded jewelry.

3. TRADE it:  Get your friends together for a jewelry party.  Everyone brings the jewelry they don’t wear and you can trade with each other.   

4. SELL it:  First, research the value of your items.  For fine jewelry, consider getting an  appraisal You can look at prices for similar jewelry on websites like eBay, but keep in mind “asking” prices may be higher than the actual sale price.  Remember that you’re selling your jewelry second-hand, not new, no matter what the condition of the piece is.

You can sell your jewelry on-line yourself (eBay or Craig’s List are some options) and there are also services that will sell your items on-line for you.  You will need good quality photos of each piece of jewelry.  Most services charge a fee either for listing an item or when the item is sold.  You may also incur mailing and insurance costs to ship the items.  If you’re selling person to person, be sure to consider your personal safety before meeting with potential buyers. 

Depending on the age and quality of the jewelry, you may be able to sell it to a business specializing in antique or estate jewelry, or to a pawn shop.  A buyer will inspect your jewelry and may test the metals and/or gems.  Keep in mind that the price they pay you must be low enough that they can resell the jewelry at a profit.  

5. CONSIGN it:  Consignment stores sell your jewelry for you at their location and keep a portion of the profit.  Check your local stores for what types of items they accept and their payment terms.

6. DONATE it:  Fine jewelry can be donated to a charity for fundraising or auction events.  Be sure to get an “appraisal for donation purposes” for tax purposes.  Costume jewelry can be donated to your local charity, thrift store, or school drama program.  Donations to qualified organizations may be tax deductible so request a receipt.

7. SCRAP it:  You can sell gold, silver, and platinum jewelry for its melt value.  When scrapping jewelry, diamonds may have limited resale value; most other gemstones generally don’t.   A reputable scrap buyer will make their offer based on a percentage of the “spot price” of the metal for that day.  It may be desirable to check offers from 2-3 businesses to see who is paying the highest rate.  Remember that precious metals used in jewelry are generally not pure (see my blog about gold here); you’ll only be compensated for the actual weight of the desired metal.

8. TRASH it:  If it’s not made of a precious metal, not repairable, and not appropriate for a donation, it may be time to toss it in the trash.

Fill your jewelry box with pieces you love and pass the rest along for someone else to enjoy! 

How Much is my Jewelry Worth?

How much is my jewelry worth?  I’m asked this at every show.  As a gemologist I can identify the gemstones in your jewelry, but to answer the question of value, the right person to ask is an appraiser.  I’ve asked my colleague, Jeanne Hawk, a GIA Graduate Gemologist, Registered MasterValuer and Certified Insurance Appraiser, to be a guest blogger this month:

Establishing and substantiating the value of an item are what appraising is all about. An appraisal is an opinion of value, a well-researched conclusion that is supported by facts which are interpreted from the marketplace. Most jewelry appraisals are done for obtaining insurance coverage. An insurance appraisal is used to determine the retail replacement value of a jewelry item. Other appraisal types include those done to determine fair market value for estate items and items sold for scrap value.

Many of my clients have jewelry of unknown identification or value. I do consultations to identify the gemstones and/or diamonds and metal karatage to determine what you have and whether you should keep it, insure, or scrap it, as is often the case with outdated gold chains. I’ll let you know the market value if you plan to sell it. And if it’s something you want to insure, I can prepare an appraisal for you.

There are six steps involved in the appraisal process as follows: 1) establish the scope of the appraisal, 2) plan the appraisal, 3) collect and analyze the data, 4) apply a valuation approach, 5) set limitations and contingency conditions, and 6) supply the final estimate of value.

At the present time anyone can call oneself a professional jewelry appraiser. However, self-anointing does not confer expertise. The key is education. A gemologist who has undergone formal gemological training, holds a degree or special education in valuation science, and has buying and selling experience either on a wholesale or retail level has the basic prerequisites of an appraiser. The valuation must be done by an individual with suitable qualifications who has no interest (no bias) in the item. Participation in professional appraising organizations is important, as well. It is critical that any jewelry appraisal be developed and written in accordance with the Uniform Standards of Professional Appraisal Practice (USPAP), authorized by Congress as the source of appraisal standards and appraiser qualifications.

I am a certified Gemoljeanne_cropogical Institute of America (GIA) Graduate Gemologist (GG), qualified to accurately identify and grade the gemstones in your jewelry. As a Registered Master Valuer™ and Certified Insurance Appraiser™, I am trained in appraisal valuation techniques and can appropriately value and appraise your jewelry. All appraisal reports are prepared in accordance with USPAP.

At your appraisal appointment, I will clean, identify, measure, weigh, grade, and photograph your jewelry. Most appointments take 30 minutes; longer appointments may be needed for multiple items. You will leave with your jewelry. In 7-10 business days, once I have completed the valuation part of the appraisal, you will receive your appraisal via email. Payment for the appraisal, and any hard copies requested, is due at the time of your appointment. Would you like to learn more about how the value of jewelry is determined?

Turritella Agate – A Snail By Any Other Name …

FTGFN105_a

Fossil turritella agate & garnet necklace (Item FTGFN105)

In last month’s blog I explained that for many gemstone beads, the country of origin may be difficult to determine.  Fossil turritella agate is an exception because it comes exclusively from the Green River Formation in Wyoming, USA.

Turritellas are marine snails (gastropods) with spiral shells.  When fossil snails were found in the Green River Formation, they looked like turritellas and were given that name.  However, it turned out that the snails were in fact an extinct freshwater variety and were renamed Elimia tenera.  By that time, the incorrect name had already become commonly used and the name elimia tenera has never managed to replace the incorrect turritella name.

Turritella fossils are among my favorite fossils to incorporate into my jewelry designs; the fossil snails are creamy to white spirals in a rich brown to almost black matrix.  The polish can be uneven on these stones due to the natural variation in the fossils, but that’s part of what makes each one unique.

The following is directly from http://geology.com/gemstones/turritella/:

“How did Turritella Agate Form?

About 50 million years ago, during the Eocene epoch, the young Rocky Mountains were almost finished growing, and the landscape of what is now parts of Colorado, Utah, and Wyoming consisted of rugged mountains separated by broad intermountain basins. Rains falling on the slopes of these mountains ran off of the land and collected into streams that carried sand, silt, mud, and dissolved materials down into the lakes that occupied the intermountain basins. Over time, these sediments began filling the lakes, and many types of fossils were preserved within them.

Abundant plants and algae grew on the margins of these lakes, providing a perfect habitat and food source for Elimia tenera, the freshwater snail. When the snails died, their shells sank to the bottom of the lake. The snails were so prolific that entire lenses of sediment were composed almost entirely of their shells.

After these layers were buried, groundwater moved through the sediments. Small amounts of microcrystalline silica that were dissolved in the groundwater began to precipitate, possibly in the form of a gel, within the cavities of the snail shells and the empty spaces between them. Over time, the entire mass of fossils was silicified, forming the brown fossiliferous agate (also known as chalcedony) that we know today as Turritella agate.”

Where do the gemstone beads in your jewelry come from?

I’m asked this question at every show.  It’s a great question but I can’t always answer it. Here’s why:

Some gems come almost exclusively from one area; fossil “turitella agate” comes from Wyoming in the U.S. and tanzanite from Tanzania, Africa. But most gems are found and mined in more than one location. For example, lapis lazuli comes from Afghanistan, Pakistan, Russia and Chile.

LLGFN104_a

Lapis lazuli from Afghanistan (with malachite and gold-filled beads, item LLGFN104

 

In some cases, especially beautiful specimens of a  gem are found in specific locations; Burmese rubies are highly prized.  Because of this, some beads are sold with their source location as part of their name; Ethiopian opal and Australian boulder opal beads are examples.

While some rough (uncut gem material) is cut and polished as gems, beads or carvings in the country where it was mined, most goes to major “cutting centers” in other countries. China and India are the biggest cutting centers for beads. Both locations produce great beads; beads from India are generally hand-made and Chinese products are often laser or machine-made. Because making rough material into beads is where the “value” is added, most beads come with labels saying they were made in the country where the cutting center is located rather than where they were mined.

So, when my beads are labeled as being from China or India, I don’t know the location of origin. But when a gem comes from only one location or when I buy directly from an importer, I know the source.

Kyanite

With a range of blue hues in a single stone, kyanite is a fabulous gem for beautiful and unique jewelry.  Kyanite has a particularly unique and interesting property: it has two  different measures of hardness in the same crystal.  A gem’s hardness is defined as its resistance to scratching and is usually stated as a single number or small range; diamond is 10 on the Moh’s hardness scale, quartz is 7.  When you look at a kyanite crystal,  it may appear to have a grain like a piece of wood; the hardness can be 5-5 1/2 in the direction of the grain and 7 across it.

Kyanite is nKYSSN102_aamed from the Greek word for dark blue, kyanos, from which we get “cyan” as a shade of blue.  Most kyanite is blue, but it can also be white, gray, orange, yellow and green.  Although still not very common in jewelry, good quality blue and green material is used for beads and cut stones.

Kyanite crystals grow in long flat “blades”.  The gem can be translucent to opaque and the color is often very unevenly zoned over the crystal.  It is a metamorphic mineral with chemical formula Al2SiO5.   It is also a “polymorph”; one of three minerals with the same chemical formula but different crystal structure (the other two minerals are andalusite and sillimanite).

Kyanite  can be found in many locations around the world including Austria, Burma, Brazil, Cambodia, India, Kenya, Myanmar, Nepal, Russia, Serbia, Switzerland, Tanzania, the United States and Zimbabwe.  Besides jewelry, kyanite is used in the manufacture of porcelain, spark plugs and  electronics.

Kyanite is fairly durable, but KYGVE102_16_ahas perfect cleavage that can cause the stone to split with a single hard knock or blow. Don’t use ultrasonic cleaners, steamers, bleach or other harsh chemicals when cleaning kyanite; use water and a mild soap.

Phenomenal! (Part 2 of 2)

Phenomenon:(noun) A special (optical) effect displayed by a gemstone when it interacts with light. Gems with beautiful optical effects are often more valuable.

Here’s a short description of types of phenomena recognized in gemology and the gems commonly associated with each.  A gem can have more than one phenomenon.

Iridescence: A rainbow display that is created when light is broken up into different colors like in a soap bubble or oil slick.
Gems: iris agate, fire agate

LASSN103_y

Labradorescence in labradorite

Labradorescence: A broad flash of color caused by light interacting with a type of crystal growth called twinning.
Gems: labradorite

Orient:  A shimmer of iridescent rainbow colors on or just below a pearl’s surface.
Gems: pearl, mother-of-pearl

OPSSN102_a

Koroit boulder opal pendant

Play-of-Color: precious opal is made up of sub-microscopic spheres stacked in a grid-like pattern. As the light waves travel between the spheres, the waves diffract, or bend and break up into the colors of the rainbow, called spectral colors.
Gems: opal, fire opal

MOSSN101_a

Adularescence in rainbow moonstone

Adularescence: A milky, bluish-white glow caused by scattering of light related to the crystal growth pattern.
Gems: moonstone

Asterism (star gems): Crossing bands of reflected light in the gemstone create a four- or six-rayed star in the dome of a cabochon.
Gems: ruby, sapphire, garnet, spinel, diopside, beryl, quartz, moonstone, sunstone

Aventurescence: A glittery effect caused by light reflecting from small, flat inclusions within a gemstone.
Gems: sunstone, aventurine, sheen obsidian

TEGFE101_a

Tiger’s eye

Chatoyancy (cat’s eye gems): A display of a band of light, like a cat’s eye. It is caused by the reflection of light from many parallel, needle-like inclusions inside a gem.
Gems: garnet, ruby, sapphire, chrysoberyl, tourmaline, beryl, tiger’s eye, quartz, moonstone, obsidian, and others.

Color-Change: Gem changes color when exposed to different types of light.
Gems: sapphire, garnet, alexandrite, spinel

Rhodochrosite, the Bacon of Gemstones

Seems like there’s been quite a bacon fad over the last year.  Well I’m sure you’ll be happy to hear that gemology has it’s own candidate for the bacon craze – rhodochrosite.

Rhodochrosite, MnCO3, is an ore of manganese.  It is a beautiful, but fairly soft (Moh’s hardness 3.5-4.0) mineral.  Most beads and cut stones show beautiful pink, brown, and white banding (described as the “bacon-strip effect”), and are opaque.  Although it is usually seen in jewelry cut as cabochons it can also be found as transparent pink to reddish faceted gems.  The banded material is also used in carvings. The name comes from the Greek rhodon -“rose” and chroma – “color.”

RDSSN102_c

Rhodochrosite and sterling silver necklace. Item RDSSN102

Rhodochrosite was initially described at a deposit in Romania in the early 1800s.  Rhombohedral crystals are mined in Colorado, where it is the state mineral.  Most of the banded rhodochrosite used in jewelry today comes from Argentina.

Rhodochrosite is a great gemstone for earrings and necklaces but generally too soft to safely wear in rings or bracelets that get heavy use.  It scratches easily so should be cleaned with a mild soap and water.

Natural or Treated? Common Gemstone Treatments

Did you know that many gemstones are routinely treated (also called enhanced)?
These treatments are generally used to change or improve the color, clarity, or durability of a gem. Some gemstones are significantly more valuable if they are not treated, but treatments allow many more beautiful stones to be made available to consumers. It is important to understand treatments are not inherently “bad” but that legally,  they must be disclosed to the customer if they are not permanent, require special care, or if they affect the value of the stone.

Here are some of the most common gemstone treatments, why they are used, and a few examples of the gems that may be treated in this way.  Sometimes more than one treatment is used to achieve a desired result.

Process: Bleach
Why: Improve color
Examples: Pearls and jadeite jade are commonly bleached to remove undesirable coloring.

PEGFN102_V2a

PEGFN103_a Pearls are commonly bleached (top) and are often dyed or irradiated (bottom)

Process: Dye
Why: Change or improve color
Examples: Stones such as lapis lazuli may be dyed darker blue to improve their color. White stones such as howlite or pearls may be dyed to resemble other stones such as turquoise or just to provide fun options for jewelry design.

Process: Fracture filling with dyes, glass, oils, polymers or resins
Why: Improve clarity and/or color
Examples: Emeralds are commonly fracture-filled to improve their clarity.

Process: Heat
Why: Change or improve color
Examples: Sapphires and amber are commonly heated to improve clarity. Tanzanite changes from brown to blue when heated and amethyst can be turned yellow and is sometimes then sold as citrine.

Process: ––Irradiation
Why: Change or improve color
Examples: Some gray pearls have been irradiated.  Colorless topaz is both heated and irradiated to create blue gems.

–Process: Stabilization/Impregnation with plastic, polymers or wax
Why: Improve durability and appearance
Examples: Soft stones such as turquoise, lapis lazuli and rhodochrosite are commonly stabilized.

Other treatments not covered here include high pressure high temperature (hpht), surface coating and lattice diffusion. You can learn more about these as well as the treatments above by clicking the GIA link below.

Peridot

Peridot, (Mg, Fe)2SiO4, is the gem quality version of the mineral olivine. It’s the gemstone for those born in August and for 15th wedding anniversaries.

Background of natural olivine crystals.

Peridot comes in a relatively narrow range of colors compared to most gemstones. That’s because the color is due to the amount of iron in the mix and not due to chemical impurities or distortions of the crystal structure. The color range goes from yellowish greens through brownish greens. Peridot crystals tend to have consistent color throughout (contrast this with a gem like amethyst which often goes from colorless through various saturations of purple in the same crystal).

From a gemology perspective, one of the cool features of peridot can only be seen with a microscope; there are often little inclusions called “lily pads” that are very distinctive and help identify the gem.

Olivine is often found in iron-rich rocks and can be seen filling the nodules left when gas escapes from molten lava. Been to Hawaii? If you go again, look around when you see the blocky types of basalt (cooled lava) with lots of holes – you may spot some olivine! It has also been found in meteorites.

There is a major deposit of gem quality peridot on the San Carlos Apache reservation in Arizona. Other notable locations for peridot include China, Pakistan, Vietnam, Myanmar, Egypt, and Tanzania.

Peridot has hardness of 6.5 to 7 on the Mohs scale. It has fair to good toughness. Warm, soapy water is the best method for cleaning peridot. Ultrasonic and steam cleaners are not recommended.
