Opal: Nature's Kaleidoscope

Opal is composed of hydrated silica spheres arranged in patterns that diffract light into spectral colors. The finest opals show broad, vivid color flashes across the full spectrum. Black opal from Lightning Ridge, Australia, is the most valuable variety.

Types of Opal

Black opal (dark body color with vivid play), white opal (light body), crystal opal (transparent), and fire opal (orange-red, often without play). Ethiopian Welo opals offer exceptional play-of-color at accessible prices. 5.5-6.5 Mohs hardness.

Frequently Asked Questions

What is play-of-color in opal?

Play-of-color is the shifting rainbow of spectral colors visible as you move the stone. It is caused by light diffracting through microscopic silica spheres.

Which opal is most valuable?

Australian black opal from Lightning Ridge with vivid red play-of-color on a dark body is the most valuable type.

How should I care for opal?

Opal contains water (5-10%) and can crack if dehydrated. Avoid extreme heat, chemicals, and ultrasonic cleaners. Store with a damp cloth.

Is Ethiopian opal good quality?

Yes. Ethiopian Welo opals can show extraordinary play-of-color. They tend to be hydrophane (absorb water) so require slightly more care.
