This is A List where people who are interested in GEMS can meet, yet the list's emphasis is OPAL. Anyone who collects, mines, cuts, deals, or affiliated with gems and crystals may join and discuss a variety of topics ranging from the mining process to the jewelry making process.
For the sake of the list being found, I will include some words and terms related to GEMS:
opal, ruby, sapphire, jewelry, gem, crystal, rock, precious, collection, collector, emerald, Lapidary, mine, diamond, contra-luz, lapis, amethyst, quartz.
