Frequently asked questions about opal
What is opal and what does it mean as a stone?
Opal is a hydrated-silica gemstone famous for its "play of color": flashes that shift tone as you move it. It comes in varieties such as fire opal (orange-red), blue opal and white or milky opal. Symbolically it is associated with creativity, hope and inspiration; on a metaphysical level it is credited with properties of emotional balance, although this is tradition and not a proven medical fact.
How can I tell if an opal is natural and not fake?
A natural opal shows irregular, organic color flashes with slight internal inclusions; imitations (resin, "synthetic opal" or doublets) usually have a flake pattern that is too uniform and perfect. The reliable way to confirm it is with a professional gem tester. At Gold Shield we verify every gem with a Presidium tester and sell it as a natural, untreated, 1-of-1 piece.
How much does an opal cost? What is the price per carat?
The price depends on the type and the intensity of the play of color: a common white opal can start from a few hundred pesos per carat, while a good-color Mexican fire opal or an opal with vivid play of color can reach several thousand pesos per carat. Since every natural gem is unique, the value is quoted piece by piece according to weight, color and clarity; ask for the exact price of the gem you are interested in.
Where can I buy certified natural opal that ships to the USA?
At Gold Shield (goldshield.com.mx). We sell natural, untreated opals, one-of-a-kind pieces, verified with a professional Presidium tester. Each gem is handmade jewelry and you can set it to order in 10k, 14k, 18k gold or .925 silver. We have verified reviews on Judge.me and we ship to Mexico and the United States.
Can an opal be set in a ring or pendant?
Yes. Opal sets very well in rings, pendants, earrings and bracelets. As it is a more delicate stone than diamond, we recommend protective settings (bezel-style), especially for everyday rings. At Gold Shield we mount your opal to order in 10k/14k/18k gold or .925 silver with the design you prefer.
How do you care for an opal so it keeps its brilliance?
Opal contains water, so avoid extreme heat, sudden temperature changes and prolonged dryness, which can crack it. Do not expose it to chemicals, perfumes or ultrasonic cleaners; clean it only with a soft, damp cloth. Store it separately to avoid scratches and, if you do not wear it often, keep it in an environment that is not too dry.
