Peridot is the birthstone for the month of August, so what could make a better gift during this month than this sterling silver necklace with its peridot cz crystal pendant. The light green stone sits in a claw setting and measures 3.5mm in diameter. The diamond cut curb chain it hangs to via the jump ring is super lightweight, comfortable and most importantly ... sparkly! It is supplied in lengths from 14 to 32 inches, perfect for both adults and children, and fastens with a spring ring clasp.
