By manufacturing our diamonds in the U.S., Spence can guarantee their origin. By eliminating middlemen, we also eliminate questionable practices. And by removing the environmental impact of traditional mining, we reduce our footprint. What you get are beautifully pure diamonds that are conflict-free and proudly crafted in the USA.
Artisan Created Diamonds aren’t dug up. They’re crafted in a plasma chamber that mimics the earth’s magma layer where diamonds naturally grow. They have the same physical, chemical and optical properties, but they’re two clarity grades higher and 33% larger than a mined diamond of the same price.
Through proprietary equipment and breakthrough technology, Spence literally replicates nature’s diamond-growing environment to produce one-of-a-kind gem-grade diamonds, each with their own inclusions, color and clarity.
Each Artisan Created Diamond is graded and certified by the International Gemological Institute, then reanalyzed by Spence experts to verify that the IGI grading meets our rigorous standards.
