This is an original Antique Ming Period (1368-1644) Porcelain Blue / White Ceramic Shard Pendant set in .925 Sterling Silver.  All of the pieces in my collection were individually handpicked by my American father, who was a Malaysian resident, and myself from antique shops in Ayutthaya, Thailand, in the early 1970's. The jewelry was purchased primarily for his antique shop located in Penang, Malaysia. This unique and genuine piece of jewelry is made from a broken piece of well over three hundred year old Chinese export porcelain produced for the domestic Southeast Asian market and was most likely found in the Chao Phraya river or Gulf of Thailand.  This Pendant's shard is slightly Oblong & is small enough to fit nicely on a necklace
