This is a fine Jadeite pendant set in 14K yellow gold. This was a clasp on an bracelet once in its life, but now it is a pendant. The pendant is hallmarked 14K. The front features a large Jade stone with apple green and white areas. The Jade is not treated, dyed or enhanced in any way. The back has Chinese lettering, probably for long life, happiness, etc. The pendant measures 1 3/8" X 1". Weight is 18.9grms. Condition is excellent. With a 10X loupe I see no chips, cracking or any damage to the Jade. The bail is large and strong. I would date this great pendant at c1960's.
