Crystal Opal

description Crystal Opal Overview

Crystal opal is a transparent to semi-translucent variety of precious opal characterized by its lack of body tone, which allows light to penetrate the stone. This transparency creates a highly vivid, three-dimensional display of spectral colors known as play-of-color. Mined primarily in Australia and Ethiopia, it is highly valued by gem cutters and jewelry designers. The stones are often faceted or cut into cabochons to enhance their optical effects.

help Crystal Opal FAQ

What is the difference between crystal opal and black opal?

Crystal opal is transparent to semi-transparent with no distinct body color, whereas black opal has a dark body tone that makes its colors stand out. The lack of body color in crystal opal allows light to penetrate, making its internal play-of-color appear three-dimensional.

How should you clean crystal opal jewelry?

Crystal opals should be cleaned gently with a soft cloth and mild soapy water, avoiding harsh chemicals or ultrasonic cleaners. Because they contain water, sudden temperature changes can cause them to crack or craze.

Does crystal opal need to be stored in water?

Unlike some cheaper opals or rough specimens, solid crystal opals do not need to be stored in water. They are generally stable if kept away from prolonged direct sunlight, extreme dryness, or rapid temperature shifts.

Why does crystal opal look so bright?

Crystal opal looks vivid because its transparent to semi-transparent structure allows light to enter deeply before bouncing back through the silica spheres. This unique optical property makes the internal play-of-color seem suspended in mid-air.
