Sterling Silver 925 Cabochon Oval Lapis Lazuli Onyx Link Bracelet 8” Thailand SU.
This is GORGEOUS! Six lapis lazuli cabochon stones separated by 5 small black onyx (?) squares and fastener all set in sterling silver (marked 925). Also marked Thailand and SU. SU stands for Sunstone (or Sun) Imports and they are manufacturers in both Thailand and Italy and export to the US and other western countries.
This bracelet weighs in at 35.6 grams so it’s not a small one. See comparison to a US dime for size of lapis cabochons.
