Selling this very heavy and pretty solid silver necklace, has about 1 oz. of silver in it. Probably from Mexico. Stones may be Chrysoprase, and blue jaspers , but not really sure what all the stones are.. Haven't had it appraised or evaluated. Stone colors may vary slightly in person due to lighting, better in person than pics. Comes with two inch chain extension to make longer . Please email me you number to get an email and text reply. Thank you.
