Transparency: It can be translucent to semi-translucent. Commonality: White opal is more common and affordable compared to black opal. Origin: Found in various places including Australia (like Coober Pedy), Brazil, and Ethiopia. Black Opal: Color: Black opal has a dark body color, ranging from dark grey to black, which enhances the brightness of its play-of-color. Transparency: It can be translucent to opaque.

Rarity: Black opal is rarer and generally more valuable than white opal due to its striking appearance. Origin: Predominantly found in Lightning Ridge in New South Wales, Australia, which is known for producing some of the finest black opals. Common Opal (also known as potch when lacking play-of-color): Color: Common opal lacks the vivid play-of-color seen in precious opals like white and black opal.
