For three generations, the Leber family has been proud to offer the finest quality responsibly sourced gemstones. Working with precious colored gemstones from a number of small, community-based mining projects and privately developed sources throughout sub-Saharan Africa, Asia, and the Americas, we hand-select only the most exquisite gemological specimens to be a part of our Earthwise Jewelry® Collection.

Our in-depth understanding of the science and politics behind colored gemstones makes us one of the most sought-after purveyors of rare and responsibly sourced gems on the planet.
