About us

DAVID CRAFT is a teaching institute founded in 1995 by David Arredondo, specialised in gemmology, jewelry creation, gemstone cutting, expertise and consulting.

David comes from a family of jewellers, who through his training and years of experience had the idea of establishing a place in Geneva of sharing and creation. He first developed the school on his own, then gradually was joined by his three sons, who today each bring their own know-how in creation as well as in teaching.
