How Spence Artisan Diamonds are made.

Atom by atom, Spence sources gem-grade diamonds that are crafted using the same process that creates mined diamonds in the earth’s mantle layer.

Good for the planet. Good for its people.

By sourcing our diamonds globally from reputable suppliers, Spence can guarantee their origin. By eliminating middlemen, we also eliminate questionable practices. And by removing the environmental impact of traditional mining, we reduce the environmental footprint on the planet. What you get are beautifully pure diamonds that are conflict-free and socially responsible.

Like traditional mined diamonds, without the mine.

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.
