Are Gilson opals real?

Gilson opals are lab-created, not naturally occurring, but they are considered "real" opals in the sense that they have the same chemical composition, structure, and optical properties as natural opals. They are produced in a controlled environment, first developed by French scientist Pierre Gilson in the 1970s. While they offer the same beauty as natural opals, they are typically more durable and affordable due to the manufacturing process. So, while not mined from the earth, they are a genuine form of opal but synthetic in origin.

How to tell Gilson Opal?

To identify a Gilson opal, which is a lab-created opal, you can look for a few key characteristics that set it apart from natural opals: Uniform Color Pattern: Gilson opals tend to have a more uniform and consistent play-of-color compared to natural opals, which may have irregular or varied patterns. The color bands in Gilson opals can sometimes appear too perfect or regular. Lack of Natural Inclusions: Natural opals often have tiny imperfections, cracks, or inclusions, while Gilson opals are usually free from these flaws due to their controlled manufacturing process. Brightness and Vividness: Lab-created opals like Gilson opals are often more vibrant and intense in color than most natural opals. This brightness can be a clue that the opal is synthetic. Laminated Structure: Some Gilson opals are created in thin layers or slices. If viewed from the side, you might notice a laminated structure, which is a sign that the opal is synthetic. Natural opals usually don’t have this characteristic. Price: Gilson opals are generally more affordable than natural opals of similar size and color, so a lower price point may suggest the opal is lab-created. Magnification Test: Under magnification, Gilson opals might display a "snakeskin" or "lizard-like" pattern, which is another indicator that they are lab-created. If you're unsure, a professional jeweler can perform tests to confirm whether an opal is natural or synthetic.

What is the rarest opal color?

The rarest opal color is red or black opal with red flashes. Red is considered the most coveted and valuable play-of-color in opals because it occurs less frequently than other colors like blue or green. Black opals with red fire are especially rare, as black opals themselves are already scarce, and when combined with the vibrant red color play, they become even more valuable. The rarity of red comes from the specific arrangement of silica spheres within the opal's structure, which must be just right to diffract light and produce this rare hue. Because of its scarcity and the striking contrast it provides, red play-of-color in opals can command very high prices in the market.
