Antonia Miletto’s web site is a feast for the eyes. Alas, it suffers from a lack of information as to materials, prices, stockists. Miletto splits her time between New York and Venice, and her aesthetic was honed by time spent in Brazil, abundant in semi-precious stones.

I believe this piece is made of what looks like petrified wood encrusted with gold-set diamonds. There are many striking pieces made with unusual materials that lend the pieces a gorgeous organic and sinuous look.

There is a contact link on her site for more (any) information.
