ABOUT CRYSTAL OPALS
Australian crystal opal is a natural precious opal known for its transparent to semi-transparent body tone and vibrant play-of-colour. Many of the world’s finest crystal opals are mined in Coober Pedy, South Australia, where opal miners have been discovering gemstones since 1915.
Unlike opaque opals, crystal opals allow light to pass through the stone, creating exceptional depth and brilliance. Each crystal opal forms naturally over millions of years, meaning no two stones are ever identical. Read more about Australian opals.
