Learn MoreThe future of fine jewelry isn’t mined — it’s refined.
Every post-consumer diamond we handle prevents new extraction, preserves our planet’s finite resources, and honors the craftsmanship already invested.
By recutting and reintroducing these natural stones into circulation, we help shape a circular, ethical, and American-made diamond economy — one that values meaning over material and permanence over novelty.
As an expert in the jewelry industry, you understand the unique qualities of diamonds mined in earlier times.
These exceptional stones, sourced from higher-grade ore bodies using selective and more destructive mining techniques, are noted for their luster, optical purity, and crystal integrity.
Many of these high-quality diamonds are found in older jewelry pieces, but often have a less than ideal cut. Yet, a trained eye can spot the exceptional radiance the lurks below the surface.
These are the diamonds we buy.
Our diamonds are the pinnacle of refinement — post-consumer stones that have been recut to achieve optimal light performance. Some of our diamonds were cut to AGS000 light performance or better.
Each one represents the union of heritage and innovation: a diamond reborn to shine brighter, and carry forward a story of responsibility and brilliance.
Our traders continuously seek out natural diamonds and gemstones with exceptional potential — stones ready to be refined and returned to brilliance.
Because we source responsibly and cut for performance, we’re able to offer a steady supply of expertly-cut, high-quality diamonds and gemstones back to the trade.
