Black Onyx Ring - Natural Onyx Band - Onyx Boho Ring

The easiest at-home method to measure your ring size is to order a plastic ring sizer, it looks like a zip tie and is simple to use. At Adina Stone, we offer a free ring sizer to help you find your perfect fit before ordering. Another option is to pop into a local jewelry store, where they can help determine your size as well. However, we always recommend staying away from string, tape, ruler, or paper measurements at home, as these methods are inaccurate and can lead to incorrect sizing.

We offer returns within 30 days. Items must be returned unworn, in their original condition and packaging, with all original components. Personalised or custom jewellery, resized rings, and made-to-order pieces are non-returnable.

If your item arrives damaged or defective, please contact us so we can resolve the issue promptly.

Tarnish is simply a natural reaction of any metal with the water, air and any chemicals (such as body lotion or perfumes). There is nothing to worry about it and it this ever happens it can be restored to its natural look cleaning in with a polishing cloth!
