Upcycled Gems and Diamonds are also known asreclaimed.They are repurposed instead of newly mined (or newly lab-grown).
Upcycled Gems and Diamonds are sourced from diamonds that were once extracted from the earth, already used in a jewelry setting, owned, loved, worn, then placed back into a new piece and creation,- which means the root origins of a repurposed diamond (and othet gemstones) are essentially impossible to trace.
So in many ways, recycled diamonds and gems are reborn into their second life on earth.
