The Brazilian jewelry designer Ara Vartanian (ara.com.br) creates innovative, bold designs such as those shown here: a 21.7-carat emerald two-finger ring with black, brown, and white diamonds, and a 32-carat kunzite two-finger ring with black and white diamonds. Prices for both pieces are available upon request. Vartanian is constantly on the hunt for unusual, large stones for his one-of-a-kind designs. Among his favorites are Paraíba tourmalines and sapphires, which he often sets in darkened gold metal to highlight their colors. The jewelry is made in Vartanian’s São Paulo workshop and sold in his three Brazilian shops and in the United States at Fivestory New York (fivestoryny.com).
