When does Brilliant Earth have sales?

Brilliant Earth typically runs promotions during Valentine's Day (early February), Mother's Day (late April/early May), and Black Friday/Cyber Monday (late November). These promotions may include 5-10% off storewide or specific categories. Sign up for their email list to be notified of upcoming promotions.

Does Brilliant Earth do price matching?

Yes. If you find an identical diamond (same carat, cut, color, clarity, and certification) at a lower price from a qualifying competitor, Brilliant Earth will review the request. Contact their customer service with the competing offer. This effectively works as a price match guarantee.

How much can you actually save on a lab diamond vs natural?

The real savings at Brilliant Earth — and any lab diamond retailer — comes from choosing lab over natural. A 1ct G/VS1 lab diamond at Brilliant Earth costs approximately $1,400–$1,600. The natural equivalent (GIA certified, same specs) costs $4,500–$8,000. That's a 60-75% saving built into the lab diamond itself — far larger than any coupon code.

Frequently Asked Questions

Brilliant Earth occasionally releases percentage-off codes to newsletter subscribers, especially around major holidays (Valentine's Day, Mother's Day, Black Friday). The best way to get a code is to sign up for their email list. That said, their biggest savings come from buying lab diamonds (40-70% below natural diamond equivalents) rather than discount codes.
