The Kit and Ace brand is a kind of stepchild of Lululemon Athletica (through family and not corporate connections). They work a lot with a fabric they dubbed technical cashmere (a cashmere blend that can be machine washed). I wasn’t aware that they also sell jewelry.
This charm, which mimics their logo, can clip onto any matching bracelet you might have but is shown with a mala bead type bracelet. it is made of rose gold plated sterling silver and set with diamonds, and sells for USD$58 (and interestingly, CAD$98 which is a pretty hefty markup even given the weaker Canadian dollar … and the fact that this is a Canadian company).
