Each Luine piece is made to order and carefully finished to our standards. Most orders arrive within 4 weeks, often sooner. We’ll keep you updated every step of the way.

Because every Luine piece is made to order, we’re unable to accept returns for change of mind. That said, we stand by our promise of quality craftsmanship . If your piece has a manufacturing fault, you're covered by our 24-month guarantee—we’ll repair it or issue a full refund, no questions asked.

They don’t. Our lab-grown diamonds are chemically, physically, and optically identical to mined ones — just created in a more responsible way.

A Luine diamond is every bit as real. Just more thoughtful.

Your IGI certificate ships with your Luine piece. You’ll also receive your diamond’s unique ID by email once it’s ready—this can be verified anytime through the IGI website.

Luine pieces are designed to be low-maintenance. To keep them looking their best, gently clean with a soft brush, warm soapy water, then rinse and dry with a microfiber cloth. Avoid harsh chemicals and ultrasonic cleaners to protect their finish.
