Vintage Jade Link Bracelet

Vintage Jade Twisted Link Bracelet with Gold Tone. Approx. 7.5 inches in length. The links of this bracelet are still in beautiful condition. The clasp appears to be a replacement and is in full working condition, however it is silver tone. With some TLC and a good jeweler this lovely vintage bracelet could be restored to its original beauty. Safety chain may be original or possibly an add-on. The safety chain clasp doesn't close completely secure. Also, the safety chain color does not match the gold color of the links which is why I am questioning whether or not is original to the bracelet. Markings - No markings found of the bracelet links. There is a "1/20th" marking (the rest was not legible). This marking was found on the safety chain clasp. Preowned and preloved.
