Our rings are comfort fit, so they can feel slightly larger than a standard band. If you were sized with a standard sizer rather than a comfort fit band, we recommend a half size smaller than your measured size.

Yes. Laser engraving on the inside, outside or both is included. Choose from 8 fonts, up to 4 symbols, or upload your own artwork.

If you want engraving but are unsure of your size, we can hold off on the engraving until you confirm the fit. Send the ring back anytime and we will engrave it at no cost. For other custom requests, contact us.

All rings are backed by a lifetime warranty covering breaking, cracking or casting defects. Plated rings should never fade, but if one does, we will send a new ring at no cost.

No. Every ring is tungsten carbide and lightly stamped "TUNGSTEN CARBIDE" for authenticity. Gold, silver and rose describe the color of the ring, not precious metal content.

Non-engraved rings can be returned for a full refund, minus shipping costs, within 60 days of purchase. Engraved rings are personalized and covered by the size exchange warranty instead.

Every order comes with a lifetime size exchange warranty. If your ring becomes too big or small to wear, we take back the original and exchange it, up to 2 times. Exchanges beyond two carry a $25 fee.

Shipping within the United States is free. Rings are made to order, so please allow 1 to 2 business days to process and cast your order. You will receive USPS tracking once it ships. International shipments may incur customs delays.

Yes. Our tungsten carbide is hypoallergenic and skin safe. Because tungsten is so hard, it does not bend or pinch, and in an emergency it can be cracked off using standard emergency tools. The tradeoff is that tungsten cannot be resized, which is why every ring includes lifetime size exchanges.
