1. What is Opal?
Answer: Opal is a hydrated amorphous form of silica, with water content that can range from 3% to 21% by weight, but usually it is between 6% and 10%. Unlike most gemstones, which have a crystalline structure, opal is amorphous, which means it does not have a definite shape or structure.
2. What Causes Opal’s Play-of-Color?
Answer: The play-of-color in opals is caused by the diffraction of light through its microscopic silica spheres. The size and arrangement of these spheres determine the colors and patterns seen in the opal. This phenomenon creates a rainbow-like effect that is unique to each gemstone.
3. Where Are Opals Found?
Answer: The majority of the world’s opals come from Australia, particularly from regions like Lightning Ridge, Coober Pedy, and Andamooka. However, opals are also found in other countries, including Ethiopia, Mexico, Brazil, and the United States.
