When it comes to color choices, October’s birthstones give you some amazing choices. Whether you choose opal or tourmaline, you’ll get a display of exciting and intense colors, making them popular choices for jewelry designers and collectors.
The name “opal” derives from the Greek opallos, meaning “to see a change (of color).” They range in color from milky white to black with flashes of yellow, orange, green, red, and blue. An opal’s beauty is the product of contrast between its color play and its background.
Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature’s heating and molding processes, the gel hardened into the form of opals. The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces is created that gives opal its radiance.
Approximately 90 percent of the world’s precious opal comes from Australia. The following are other countries that produce precious or fancy varieties: Brazil, Mexico, United States, Hungary, Peru, Indonesia, Honduras, Guatemala, Nicaragua, Slovakia, Czech Republic, and Ethiopia.
Each opal is totally unique, like fingerprints!! To get a really good look at the opals in these designs, click on the images below for a larger view.

Since tourmaline is available in a wide variety of colors, it is ideally suited to almost anyone’s taste. It is known for displaying several colors in the same gemstone. These bi-color or tri-color gems are formed in many combinations; the gemstones with clear color distinctions are highly prized.
Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA.
The following designs feature the varying hues of tourmaline. Click on the images to see a larger view.

As we turn our calendars to September, we start thinking of things like heading back to school, sipping on a pumpkin spice latte, and planning our fall fashions. For those celebrating a birthday in September, they’re thinking of their birthstone: sapphire!
Although sapphire typically refers to the rich blue gemstone variety of the mineral corundum, this royal gem actually occurs in a rainbow of hues. Sapphires come in every color except red, which would then be classified as ruby.
Trace elements like iron, titanium, chromium, copper, and magnesium give naturally colorless corundum a tint of blue, yellow, purple, orange or green, respectively. Sapphires in any color but blue are called “fancies.”
Pink sapphires, in particular, tow a fine line between ruby and sapphire. In the U.S., these gems must meet a minimum color saturation to be considered rubies. Pinkish orange sapphires called padparadscha (from the Sri Lankan word for “lotus flower”) can actually draw higher prices than some blue sapphires.
Due to the remarkable hardness of sapphires—which measure 9 on the Mohs scale, second only to diamond—they aren’t just valuable in jewelry, but also in industrial applications including scientific instruments, high-durability windows, watches, and electronics.
Sapphires make stunning gifts for anyone born in September or celebrating a 5th or 45th wedding anniversary, so be sure to visit an AGS jeweler. They will help you find that perfect gift, whether you’re seeking the classic blue or another shade from the sapphire rainbow.

If you’re looking for a style that takes traditional in a different direction, check out the east-west setting. It’s the lastest jewelry trend that places the gemstone horizontally vs. the classic vertical setting. Whether the cut is oval, pear, marquise, or emerald, the east-west setting will be noticed!
We’re spotlighting a few designs from our AGS members that feature this eye-catching setting. Click on the images to get a closer look at east-west settings in rings and necklaces.

Throughout history, gold has been one of the most sought-after metals in the world. It’s been used as currency, to decorate objects as a thing of beauty, and is also used for industrial purposes.
“Reflections” ring made of 24k hammered gold set with diamonds, by Lika Behar Collection.
In the jewelry industry, the word “gold,” when used by itself, means “all gold” or “pure” gold, meaning 24 karat (24K) gold. Because 24K gold is soft, it’s usually mixed with other metals called alloys to increase its hardness and durability. If a piece of jewelry is not 24 karat gold, the karat quality should accompany any claim that the item is gold.
The karat quality marking tells you what proportion of gold is mixed with the other metals. Fourteen-karat (14K) jewelry contains 14/24 or 58.3% gold, with 10/24 parts of an alloy metal. The higher the karat rating, the higher the proportion of gold in the piece of jewelry.
Jewelry should be marked with its karat quality. Near the karat quality mark, you should also see the name or the U.S. registered trademark of the company that will stand behind the mark. The trademark may be in the form of a name, symbol or initials. If you don’t see a trademark accompanying a quality mark on a piece of jewelry, look for another piece.
Are you ready to go for the gold? Below are some designs from our American Gem Society members that feature yellow, white, or rose gold, which is a mixture of gold with copper to create the pinkish, soft glow.

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!

Jewelry 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 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.
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.
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.

Summer days are full of fun with days at the pool, barbecues with friends, and travel to beautiful beach locations. But all this fun can lead to your jewelry losing its sparkle as it becomes dulled by the oils in your sunblock, butter dripping off that cob of corn, or caked with sand from building a prize-winning sandcastle.
So, when you want to return your jewelry to full sparkle, you may be tempted to use one of your mother’s or grandmother’s tricks of the trade. But these “old wives’ tales” range from ineffective to dangerous. Here are the top eight jewelry cleaning tales to avoid.
#1 – Toothbrush and Toothpaste
They are great for your pearly whites, but not your pearls or any other type of jewelry. The abrasives in toothpaste will scratch the surface of metals and softer gemstones, while a toothbrush’s long handle places to much pressure on the piece you are cleaning.
#2 – Ammonia, Windex®, and Mr. Clean®
Ammonia, Windex, denatured alcohol, acetone and other harsh cleaning agents can dull or pit the surface of softer gemstones. While ammonia or a cleaning agent like Mr. Clean can be safe on harder gemstones in small concentrations, it is difficult to determine the correct ratio, making them a risky choice.
#3 – Hydrogen Peroxide
While many of us know hydrogen peroxide to be an effective disinfectant, it is not really designed to be a cleaner. In some cases, it can actually react with sterling silver and through a chemical reaction, harm the finish. Professional products are a much better bet.
#4 – Bleach
Bleach is not safe for cleaning jewelry, as it damages metal alloys in gold, irreparably damaging the piece. In fact, this is why it is not a good idea to wear your jewelry while swimming or in a hot tub because both bleach and chlorine are often used to clean them.
#5 – Vinegar and Lemon Juice
The old wives are big fans of vinegar and lemon juice, and they are great cleaning agents for many things. Just not for jewelry. Both are too acidic and abrasive, which is damaging to metals and softer gemstones.
#6 – Coca-Cola®
Yes, some (Do it Yourself) DIY sites suggest using Coca-Cola for cleaning jewelry, but like vinegar, the acids in Coke can damage metals and softer stones. But to cool off on a hot summer day? There’s nothing like it.
#7 – Baking Soda
Baking soda, also known as bicarbonate of soda, is another popular DIY cleaning agent. However, it is too alkaline for cleaning jewelry safely. Just leave it in your fridge to soak up unpleasant odors.
#8 – Boiling Water
Although steam is an excellent way to clean jewelry (most jewelers use a steamer), placing your jewelry in a pot of boiling water is not a good idea. Your piece will come into contact with a hot metal surface, which can weaken or misshape the metal.
While the old wives’ tales are not the way to go, you can clean your jewelry at home. Visit your jeweler for professional jewelry care products formulated especially for cleaning jewelry. Be sure to ask what formulation is best for the jewelry you need to clean. For example, you will want a gentle jewelry cleaning formulation for pearl and other delicate gemstones.
