Setting our Sights on Sapphires

By Robin Skibicki

As we change our calendars to September, our sights are set on cooler weather, and on sapphires!

Sapphires are known for their beautiful blue hue, but they can also be found in a variety of pinks, yellows, and oranges, even peach, green, and violet colors. These colors are referred to as fancy sapphire.

One of the most sought-after fancy sapphires is the padparadscha. Its pink-orange coloration can be compared to that of a tropical sunset. Princess Eugenie, a cousin to Princes William and Harry, received an oval cut padparadscha sapphire ring for her engagement, bringing this rare gemstone into the limelight.

Sapphires can also display the celestial-like optical phenomena, asterism, adding the name “star” to this type of sapphire.

There is a Cure for the Summertime Blues

By Donna Jolly, RJ

As summer stretches out toward its final dog days, and the thermometer keeps bobbing toward the high end, you are probably feeling the need to cool down. We have some nice ice to help. As usual with us, it’s the jewelry kind of ice.

Let’s look at five amazingly lovely pieces of jewelry we’ve recently featured on our AGS Facebook page to help us take our minds off of the temperature.

First up, these blue topaz and peridot earrings, and blue topaz pendant, from Goshwara are as calming and cool as the ocean itself.

Staying with the light blues, we love this custom engagement ring from Tacori:

Spinel: The Coolest Gem You’ve (Probably) Never Heard Of

By Isabelle Corvin, CG, Staff Gemologist at Panowicz Jewelers

Three Spinel Crystals

Red Spinel

Spinel is an oxide mineral that crystallizes in the cubic structure and has quite the mixed-up history.

As of 2016, it is also the newest birthstone to be added to the birthstone list! August babies now have a choice between vivid peridot and alluring spinel.

The word “spinel” comes from the Latin word Spinella, which means “little thorn” or “arrow-shaped.” Spinel gems come in a wide range of colors and saturations, though perhaps the most famous (and mistakenly infamous) is the red variety.

In ancient cultures, red spinel was always grouped together with rubies, and sometimes garnets, since the rough (and even polished and cut) crystals look so similar. In the modern age, the gems can be separated, but much of spinel’s history is tied up in the lore of rubies.

The oldest known spinel dates back to 100 B.C. and was found in Kabul, Afghanistan, inside a Buddhist temple. Red and blue spinels were also being used in crafting by the Romans.

The most famous spinel is also the most famous example of mistaken identity in all of gemological history. A “ruby” known as the Black Prince’s Ruby is our culprit. It is a red gem set in the Imperial State Crown of the British crown jewels. The gemstone is uncut, but polished, and weighs approximately 170 carats. The gem has never been removed from its original setting, so the weight is only estimated.

This amazing gemstone, however, is no ruby. It is, in fact, a spinel.

The Black Prince was the son of Edward III, and reportedly received the gem from Don Pedro the Cruel, King of Castille as a reward. Legend has it that the spinel was one of the gems worn by Henry V on his helmet and that it deflected a fatal blow, saving his life during the Battle of Agincourt.

Whether true or not, the gem was thought to be ruby for many years, until technology and the knowledge of gems improved enough to separate gems on more than mere color.

This royal stone is not the only spinel in disguise. Empress Catherine II of Russia had a crown that bore an estimated 400-carat spinel. Likewise, Queen Victoria had a very dark red spinel called the Timur Ruby.

It doesn’t help matters when spinel and ruby often form together in the earth! In 1783, mineralogist Jean Baptiste Louis Rome de Lisle finally separated spinel from ruby, realizing that the two minerals were completely different.

Further confusion arises with spinel’s true nature even now.

Many pieces of inexpensive birthstone jewelry have an imitation of the true birthstone: something that looks like—but isn’t—the real thing. The majority of these are made with synthetic spinel, grown in a laboratory rather than the ground, but boasting the same chemical make-up.

The natural gem is lovely, but many only know of its synthetic counterparts.

Each color of spinel is thought to provide different benefits to the wearer, from protection to enhancing creativity and kindness, to better cognitive abilities. Colorless spinel is rare, and no current mines exist that produce it.

The most common colors seen in jewelry are red and blue, with the hues ranging from highly saturated to perfectly pastel.

Other popular colors are yellows, purples, and pinks, although the gem comes in every color. Black spinel is found in many pieces, and once again, is often confused for other black gems like hematite, black diamond, and black onyx.

Spinel is mined in many locations, including Madagascar, Sri Lanka, Myanmar (formerly Bruma) Brazil, Sweden, Pakistan, and Russia, among others. It can even be found in the USA.

Additionally, small crystals have been found on meteorites, a trait spinel shares with the other August birthstone, peridot.

For a gemstone many have never heard of, it might be the most famous of all. It is the hidden star of the show, silently shining on as the world ignores it or mistakes it for another stone altogether.

But spinel is worth a first, and second, glance. With spectacular colors, excellent durability and an amusing history, it’s the perfect addition to anyone’s gem and jewelry collection.

Spinel truly deserves the title: The Coolest Gem You’ve (Probably) Never Heard Of!

What’s That Bracelet (REALLY) Worth?

By David Craig Rotenberg, ECGA (AGS), GG (GIA), CSM (NAJA), CAPP (ISA)

 

Gold Jewelry  With Gems , Chains Close Up Macro Shot Isolated OnJewelry appraisals are important documents that are required for insurance valuations, the settling of an estate, determining the value for tax deductions for charitable contributions, for casualty loss evaluations, or perhaps the division of property in a divorce.

The appraisal is simply a means of factually communicating what a piece of jewelry is worth. It’s the item’s value assessed by quantitative and qualitative aspects as determined by a skilled professional appraiser. This individual should not only understand the science of valuation, but should be able to properly communicate the background on exactly how he or she arrived at that assessment.

Insurance Appraisals

Insurance appraisals are used by insurance companies to determine exactly what cost is required to replace an exact piece of jewelry in the current climate in the event of theft or loss. The appraiser provides a full evaluation of the item, including a detailed description of quality and special nuances of the item. While each insurance company may operate differently, most won’t simply accept purchase receipts since the determined “value” is the key when writing a policy or reimbursing a claim.

Appraisal

Settlement Appraisals

It is especially important to have an experienced appraiser when appraising for tax purposes. When someone dies, jewelry must be categorized to determine fair market value in regards to inheritance tax as applied by the IRS. Fair market value is a different determination than replacement value, which you obtain for insurance purposes. In terms of a divorce, an appraisal might be required to help determine equitable distribution of property. Jewelry is part of the “estate” and needs to be categorized for tax purposes.

The Process

After you contact a jewelry appraiser, they will sit down with you and review the items you want to be appraised. The condition of an item is extremely important; a broken watch from the 1960s, for instance, might be valued like a typical flea market item while a vintage Rolex in great condition from the same time period would be appraised at what it would bring on the second-hand market. Diamond rings normally have laboratory reports evaluating their quality. New jewelry that is being appraised for insurance purposes should be accompanied by receipts from the store where purchased so the appraiser can refer back to the original jeweler if there are questions.

 

Finding a Qualified Jewelry Appraiser

You can contact the American Gem Society (AGS) for a list of certified appraisers in your area. Certification by the AGS indicates that the individual is not only a certified appraiser, but also an expert gemologist. The AGS is one of the oldest nonprofits dedicated to consumer protection in the industry. A certification will usually be displayed in the appraiser’s workspace—this certificate required a lot of time and effort and the appraiser will want to show it off!

Other reputable organizations include the National Association of Jewelry Appraisers (NAJA) and the American Society of Appraisers (ASA). Some people ask if it’s necessary to obtain two appraisals; in most cases, this shouldn’t be necessary, especially if you’re confident you’ve gone to a qualified appraiser.

Over the Years

Before the 1980s, there wasn’t a lot of formal appraisal education and a jeweler might simply assess an item for what they might sell it for in their own showcase. The average jeweler didn’t have a lot of resources—an item might be sold based on what someone told them it was worth.

With the founding of the International Society of Appraisers (ISA) in 1979, appraisal education became more of a studied science. As gemology education blossomed, jewelers were able to conduct research, compile pricing information and attend continuing education as they used their new-found gemological skills for buying and appraisal purposes. Transparency is critical—an appraiser must be able to thoroughly explain how they arrived at a value.
