Calibrated turquoise is pretty common in the gemstone market today, but what does it actually stand for? When you hear the word calibrated coupled with the word turquoise, it makes you wonder how it actually works. Because turquoise is so soft and unique in color and pattern that it just can't be cut into the same size, or look exactly the same. Is calibrated turquoise real turquoise or made of resin or some other synthetic material?
What is Calibrated Turquoise
Calibrated turquoise is turquoise that is cut to fit standard size commercial gemstone jewelry mountings and settings, just like many gemstones that adhere to standard jewelry setting measurements, such as 7mmx9mm, 8mmx10mm, etc.
The nature of turquoise being relatively soft, therefore, even the highest grade natural turquoise needs to go through a certain enhancement (stabilization) process to be cut into precision without breaking.
The stabilization process was invented in the 50s in Arizona and was soon adopted globally. Essentially, the stone is put under pressure to absorb a clear epoxy filler which makes the stone much stronger to cut and polish.
Setting the record straight, calibrated turquoise does not mean it is fake. Stabilization is a necessary process to make natural turquoise hard enough to be shaped. In fact, the higher-grade natural turquoise is dense enough to be cut and shaped without too much enhancement. The higher the quality of the stone is, the less stabilization it undergoes. On the other hand, a softer and lower grade of turquoise needs to have more treatment and requires more stabilization.
In fact, calibrated turquoise can be more expensive than freeform turquoise cut from the same rough, because the yield rate of calibrated turquoise is so much lower, sometimes even below 10%.
Market of Calibrated Turquoise
The need for calibrated turquoise sprung as more jewelry makers want to have materials that possess the same size casting or bezels whenever they have top-selling styles that require personality and the same size - this is especially true with designer brands.
Some independent jewelry designers go for calibrated turquoise too whenever customers request for the same design, making it easier for jewelry-makers to produce more of the same.
Take for example turquoise earrings - designers love to use calibrated ones in order to achieve the same size for each pair, making their designs as symmetric as possible. Adding to that, traditionally, native designers love the same-sized materials when creating clustered flowers and squash blossom necklaces.
A lot more jewelry designers just simply like the small or unique sizes of the calibrated turquoise, and when paired with its natural unique color the jewelry piece is surely one of a kind!
Reconstituted and Fake Turquoise
Calibrated turquoise is well sought after in the market by jewelry-makers, silversmiths, metalsmiths, and the love for their process of standard fitting creation while keeping the uniqueness of each piece. In the meantime, natural calibrated turquoise stones are quite rare and difficult to cut due to different factors. You may have heard of depleting turquoise mines and mines that have uncooperative weather conditions that make it hard to produce a ginormous percent of yield. So there comes the presence of reconstituted and fake turquoise.
Reconstituted turquoise mixes crushed turquoise power with epoxy. Usually, there is very little natural stone in reconstituted turquoise, instead, it contains mostly resin and dyes.
Fake turquoise is the ones that do not even contain any turquoise presence. One of the most popular ways is by dying a Howlite to imitate the color of turquoise. You'd also be surprised by the amount of plastic-made imitation turquoise!
Luckily, there are ways and tell-tale signs in distinguishing if your turquoise piece is a fake. Think price, appearance (overall look), and color.
As most turquoise enthusiasts know, turquoise is of high value so if you see someone selling it for next to nothing, that’s just too good to be true! As for the appearance, if you have a natural stone make sure to do the fingernail test. Run your fingernail across the surface of the stone - once your fingernail gets caught on where the turquoise meets its webbing, you have a real one! You can also scratch your turquoise surface - if it scratches easily, it’s fake. Lastly, if your ‘turquoise’ is only dyed in Howlite, you can perform a nail polish test. Get a cotton ball and apply nail polish, apply some of it to an area of your stone - if it is just Howlite, it will render a blue color on your cotton ball.
