Alexis Canter creates beautiful jewelry from casts of baby teeth, coffee beans, chicken bones and other organic remnants. The Brooklyn based designer's signature piece--a 14k gold casting of the winning half of a wishbone--makes a perfect good luck charm and the 14k gold baby teeth earrings (pictured) are the ideal synthesis of creepy and cute. Available at Stuart and Wright in Brooklyn the "Lucky Half" is $150 in silver and $400 in 14k gold, the baby teeth earrings are $190 and a solid 14k gold coffee been pendant is $436.
