How to Identify Opal
Opal is hardened silica gel: hardness only 5.5–6.5, waxy-to-pearly luster, conchoidal fracture, and noticeably lighter than quartz. Precious opal flashes shifting spectral color; common opal is milky, honey, or green without fire. Field-check suspect seams with a flashlight from behind — opal transmits a soft glow. Freshly dug opal can craze as it dries, so keep finds damp.
