Frank Wang’s interest in importing began as the owner of a small retail gift shop in the San Francisco Bay area back in the 1990s and early 2000s. Today, Frank is the company owner of J.K. Stone USA, which operates the J.K. Stone USA showroom in Lakewood, Colorado, and two wholesale warehouses, one in Denver and another in Tucson. In addition to his showroom and warehouses, Frank hosts the J.K. Stone Denver Warehouse Show, an official show of the annual Denver Gem & Mineral Showcase in September, and the J.K. Stone Tucson Warehouse Show, one of the 40+ official shows of the annual Tucson Gem, Mineral & Fossil Showcase in January-February.

Stone Carving Seller to Denver & Tucson Show Promoter

While visiting his hometown of Shenyang, China, Frank purchased a few serpentine and jade carvings crafted by artisans in a nearby village to sell in his gift shop. His appreciation for the carved stone art quickly grew into a thriving business. In 2001, Frank began selling Chinese-crafted carvings and other stone products at the Tucson Gem, Mineral & Fossil Showcase and the Denver Gem & Mineral Showcase. By 2005, Frank had established a successful business importing high-quality mineral specimens, polished products, and metaphysical goods directly from China, Madagascar, Brazil, and Morocco. Frank moved his operations from California to Denver and Tucson in 2014.
