Sterling Silver, 22K gold.  This sweet little diamond is a REAL salt and pepper diamond, set in 22K gold. It is really sparkly!  The rustic shank was made by heating the surface of the silver and carving into it with a stylus (PLEASE SEE THE VIDEO THAT GIVES A SENSE OF THE SCALE) Size 8. I am sorry IT IS NOT sizable.   EXCHANGES ACCEPTED WITHIN 10 DAYS FROM RECEIPT.
