Buying Tips from Our Gemologists
Judge opal by the brightness, pattern, and color range of its play-of-color — not the base. Black opal from Lightning Ridge with a vivid, broad flash is the world's most valuable. Beware doublets and triplets, which are thin slices bonded to backing.
Caring for Your Opal
Opal contains water and can crack if it dries out or suffers sudden temperature change. Never use ultrasonic or steam cleaners — wipe gently with a damp cloth and store with a damp cotton pad.
