The story behind Diamonds-USA.
Loose diamonds, lab grown diamonds, and custom engagement rings at Diamonds-USA.com. Trusted in North America since 1997. Free insured worldwide shipping.

Visit diamonds-usa.comSix ways to save more, every time.
Reveal, then paste at checkout
Pick a code above and hit “Show code”. We copy it to your clipboard and open diamonds-usa.com so you can paste it straight into the promo box before you pay.
Always check sitewide before product-specific
Sitewide Diamonds-USA codes apply to your whole cart and often stack with free-shipping thresholds, while product codes lock you into a single item. Start broad, then narrow.
Build your cart first, then test
Most percentage codes have a minimum order threshold. Assemble the cart you actually want — a code that looks small can become significant on a larger order.
First-order pop-ups are negotiable
Open diamonds-usa.com in a fresh incognito window — the welcome pop-up almost always offers 10–15% off your first order, and it usually stacks with our verified codes.
Cart-abandonment unlocks a better code
Build your cart, close the tab, and wait a day. Many retailers email a recovery code a few points above their public offer. Couponly auto-detects these too.
Let the extension do it for you
Install Couponly’s free extension and it tests every working Diamonds-USA code at checkout, then applies the best one automatically — no copy-paste.
