This is a magical one-of-a-kind opal that catches the light in so many amazing ways. The opal is set into a luxe 1.5mm 18k gold chain that has a wonderful weight and presence. The opal is wrapped in a 22k gold bezel. This anklet is one-size-fits-most and measures 10 ½ inches long. Choose between two gold clasp options: handmade (beautiful and functional s hook closure, best for pieces you frequently leave on) and machine-made (teardrop lobster which locks, best for pieces you take on and off frequently).
