Opals flash with rainbow color that no other gemstone can match, but they need careful handling. This guide covers opal types, how to judge quality, and the do-and-don't care rules that keep opals beautiful for decades.
White and crystal opals show classic play of color, black opals from Australia are the rarest and most valuable, and boulder opals retain their host rock for a natural look. Fire opals are prized for warm orange body color with less play of color.
| Factor | What to Look For |
|---|---|
| Play of color | Bright, full-spectrum flashes |
| Body tone | Darker body tone increases value |
| Pattern | Harlequin and broad flash patterns are prized |
| Origin | Australian black opal is the benchmark |
Opals are soft and water-sensitive. Avoid ultrasonic cleaners, heat, and sudden temperature changes. Clean gently with a soft damp cloth, and store opals in a slightly humid cloth away from hard stones. Solid opals are safer for daily wear than doublets.
