Opal stones have a unique charm. Whether for a birthday gift or for self-satisfaction, October's birthstone is renowned for its unique color and brilliance. The opal jewelry trend is becoming even more popular in 2026, thanks to increasing demand from designers and collectors. But not every opal is the same, so buying guides and price-quality information are crucial.
What is Opal?
Opal is a unique gemstone because it is not crystal-like, but rather composed of tiny silica spheres. These tiny spheres refract light, giving it a rainbow-like sheen or play of colors.
There are two main types of opal
-
Precious opal – It has uniform spheres and vibrant colors.

Opal Jewelry Tips

Triplets and Doublets: Protective layers for thin opals increase durability and reduce cost.
How to Identify a Genuine Opal
Look carefully at your opal from the side. Do you see distinct layers? If so, you may be looking at a doublet or triplet, not a solid, single-piece opal. A doublet is essentially a thin slice of opal glued to a darker backing to make it appear more vibrant. But a triplet takes it a step further it adds a clear, dome-like layer on top, which protects the opal and gives it more sparkle.
Turn the stone over and look at the back. Does it look like black and gray plastic? This is often a triplet resting on a backing of black plastic, glass, or vitrolite. Doublets are a little trickier their backing may be natural, such as a thin layer of potash or ironstone, which is the host rock of boulder opal.
Here's a telltale sign: look at the side again. The "join" between the opal and its backing is important. Solid opals typically have a slightly bumpy, natural curve at this point, reflecting how they formed in the Earth. Man-made layers? These are glued flat, forming a straight, flawless line.
Pro tip: If your opal is already set in jewelry and its edges or backing are hidden, it can be difficult even for experts to tell. But knowing these signs can help you identify doublets and triplets when shopping or collecting.
-
Fake: Plastic/glass, soft, no phosphorescence, does not diffract light.
-
Treatment: Wax, oil, smoke, or dye. Always confirm disclosure with the seller.
-
Hydrophane opal: Absorbs water and chemicals careful handling is required.
-
Synthetic/lab-created opal: Natural but grown in a lab. The pattern resembles cellular or snakeskin.
