Limited lifetime warranty is included with purchase (does not apply to sterling silver or titanium jewelry). Once the duration of the return/exchange period has passed, the terms of the limited lifetime warranty come into effect and covers size exchanges or damage to tungsten metal (not inlays, stones, plating, or additional materials on the ring). Each lifetime warranty claim incurs a nominal fee of $9.95 USD for domestic customers ($14.95 USD for international customers). This includes processing, replacement and/or repair of the ring, and shipping of the new replacement with delivery confirmation/tracking number. Please note, items cannot be replaced with a different model unless the original model is no longer available. Any engraving or willful alterations to item will void all returns, exchanges, and warranties offered.
