A delicate layering piece that adds elegant movement to any look. The Ava Necklace features a 4mm lab-grown opal set in a 6-prong setting with a fine box chain drop that gracefully extends 2" below the stone. The adjustable chain allows you to wear it at 16" or extend it to 18" in length, with the opal sitting perfectly at the 18" mark when fully extended. We chose lab-grown opal for its superior durability and color stability, unlike natural opal, which is soft and prone to cracking or color changes, lab-grown opal maintains its brilliant iridescence and is resistant to damage, making this necklace perfect for daily wear.
