This flat white jade square with 4 holes was purchased on one of my China trips. This piece may have formed part of a jade belt or it could be a Pei. A jade pei is a pendant used in ancient times as a decorative ornament , stitched with silk threads to other items to form a belt or chateline.
The color is greyish white with low relief carving showing a pattern of interlocking long "S" scrolls and short "C" scrolls and the same pattern is repeated on both sides. There are small patches of white calcification on the surface and this whitening appears on both sides which maybe evidence of antiquity.These aging marks make me optimistic(though not postive) that my jade square may at least be Ming if not Han.
Using snake knots and Pyu green glass beads, I converted this last ramnant of an ancient jade belt or pei into a unique pendant necklace with a long history.
