Opal and cubic Zirconia heart pendant necklace

Opal heart shaped pendant with CZ never worn. It sat in my drawer for years because the necklace is so thin and my toddler is handsy. I don't believe it's gold might be Silver. Perfect gift for the special October birthday person in your life. The opal has a peach undertone and shines in greens yellows and blues. Still has the tag but the setting is a bit ripped when i tried ti remove the tag to show the price.
