American-mined diamond pair from the now-closed Kelsey Lake Mine in Colorado. The rough crystal retains its natural octahedral form with visible etching and subtle color zoning, while the cut counterpart is a round brilliant showcasing excellent light performance and a slightly warm tone characteristic of this locality. Kelsey Lake was one of the only modern diamond mines in U.S. history, producing a limited number of gem-quality stones in the 1990s. Rare opportunity to own both stages of a fully traceable American diamond
Gemstone 1.9 x 1.9 x 1.1 mm / .02 carats
