Amid the diamonds and precious gems at this year’s Tucson Gem & Mineral Show, there is a fun little booth to check out called Lauren-Spencer Group LLC. The company carries these cute desert crystal pins of cactuses, Wildcat paws and “Wild Cats” pins. Lauren-Spencer also has the delicate, drapey necklaces that the younger set loves, along with initial necklaces and horoscope bracelets. The company visits shows all over the U.S., but only in Tucson can you buy the jewelry outright, instead of order it.
