Whether you’re a soothsayer, healer or a simple admirer of Mother Nature’s ability to transform a pool of molten rock into sparkly gems, minerals are fascinating. It’s no wonder why the traveling Gem Faire hosts nearly 50 shows a year for all the lapidary aficionados among us. The Gem Faire returns to Sacramento at the Scottish Rite Center (6151 H St., Sacramento) for its 30th year from Aug. 9–11 to show off its merchant’s shiny wares, including jewelry, crystals, gems, beads, minerals, gold, silver and even fossils—for the more paleontologically inclined. Since the vendors sell directly to customers, prices should be cheaper than what you’d normally find in a store. And in case you do decide to pick up a diamond ring or two, or if the old wedding band is looking worse for wear, the Gem Faire offers on-site jewelry repair, cleaning and sizing while you shop. The three-day event, which runs from noon–6 p.m. on Aug. 9, 10 a.m–6 p.m. on Aug. 10 and 10 a.m.–5 p.m. on Aug. 11, charges $7 for weekend passes. Tickets are currently buy-one-get-one-free on the Gemfaire.com website, which you can visit for more info.
