Leading Diamond Buyer in Denver & Colorado

For over two decades, we’ve earned our reputation as a leading diamond buyer in the Southwest and now proudly serve clients throughout the Denver metro area and the Colorado area. Unlike many buyers who act as middlemen and resell to larger dealers—often resulting in lower offers—we are a direct buyer and one of the largest estate jewelry buyers in the region. By sourcing diamonds directly from sellers for our retail stores, we’re able to offer significantly higher payouts, backed by our inventory of over $25,000,000 in fine jewelry in our retail stores.
