What opal mine in nevadas virgin valley produces the most stable opal?
There are nearly 200 mining claims and 5 patented (private) mines in Virgin Valley. Several are open to public digging (Royal Peacock, Bonanza, and Rainbow Ridge). Of these three public mines, the Rainbow Ridge produces the most stable opal, according to Eckert (1997) "The World of Opals." The stability of the opal depends on its primary formation and to a lesser degree the moisture content of the enclosing deposit. A dry bank will produce more stable opal than a wet one (generally). A large amount of opal from the Royal Peacock is actually stable. Most opal in Virgin Valley cracks (known as crazing) shortly after mining. Keeping it moist and out of direct light, and later drying methods, will 65% of the time produce dry stable opal for cutting.
