Szul offers this 1.15-Carat Peridot and Diamond Pendant in Sterling Silver for $21 with free shipping. That's $128 off list price and the lowest total price we could find by $9, although we saw a comparable diamond and peridot pendant for $2 less last week. It features a 9x7mm 2.5-carat AA+ oval-cut peridot gemstone and four accent diamonds totaling 0.03 carats, all set in solid .925 sterling silver. An 18" sterling silver chain is included. Deal ends August 9 at 8 am ET.
