Ritani Diamond Dash promotion lists both 30% and 45% lab-grown discounts

Ritani rolled out a limited-time "Diamond Dash" campaign in early March 2026 that the company describes as tiered discounts across lab-grown diamonds, engagement ring settings, wedding rings, fine jewelry, and gemstone pieces, and the promotional copy calls out "notably 30% off many lab-grown diamond." At the same time, Ritani's own Current Offers and Terms & Conditions pages list a separate headline, "Lab Diamond Flash Sale: 45% Off," with the explicit instruction to "Save 45% on select Lab Grown Diamonds within the specified collection when you use code FLASH45."

The FLASH45 listing carries specific restrictions: "This promotion cannot be applied retroactively and is not valid on any other products outside of the specified flash sale collection," and "The discount does not apply to sales tax, shipping fees, or any other charges." The site repeatedly warns that "All discounts are subject to availability while supplies last," and that the FLASH45 savings apply only to "select Lab Grown Diamonds within the specified collection," which suggests the 45 percent offer is limited to particular SKUs rather than a blanket price cut across all lab-grown inventory.

Compounding the confusion, Ritani's Current Offers page also advertises "Shop for Lab Grown Diamonds at Up to 30% Off" and lists multiple overlapping promotions including "Up to 30% Off Sitewide," "25% Off Sitewide," and "45% Off Select Lab-Grown Jewelry." The site header states "These offers are available for U.S. & Canadian customers only" and plainly instructs that "Customers cannot combine discount codes at checkout," meaning a shopper cannot stack FLASH45 with any other marked sale or coupon at purchase.

The company's jewelry markdowns carry firm consumer implications. The "Jewelry Sale: Up to 60% Off Select Jewelry" entry includes hard terms: "All items included in this jewelry sale are priced as marked, with no further markdowns or adjustments available," and "All purchases made during this promotion are considered final sale, and as such, no returns, refunds, or exchanges will be accepted." Those clauses apply to items in that specific sale collection and underline that some bargains are sold final even when they sit alongside coded promotions elsewhere on the site.

Referral incentives are similarly inconsistent across materials. MarieClaire's summary of Ritani deals records a referral scheme that gives a friend "$100 off their first Ritani order" while the referrer receives a "$25 gift card." Ritani's own snippet language elsewhere lists "$50 off with Friend Referrals" and an incomplete "Give friends $ off their first order," leaving the exact mechanics and dollar amounts unclear on the company's public pages.

For consumers hunting lab-grown diamonds, the difference between a 30 percent and a 45 percent discount is consequential, and Ritani's mix of press language, sitewide headlines, and flash-sale codes demands specificity. The retailer's publicly posted terms do make some constants clear: most discounts apply to merchandise subtotal only and exclude taxes and shipping, offers are "while supplies last," codes are non-combinable, and select sale merchandise is final sale. Buyers seeking the deepest savings should examine the SKU lists tied to FLASH45 and the Diamond Dash tiers at checkout, and expect Ritani to reconcile which collections carry the advertised 30 percent tier and which are limited to the FLASH45 selection.
