Black Friday & Cyber Monday Diamond Jewelry Sale

Our Black Friday and Cyber Monday sale runs from 10 November to 30 November 2026. Black Friday falls on Friday 27 November and Cyber Monday on Monday 30 November, the final day of the sale. Every piece below is included, from everyday diamond studs to the engagement ring you have been waiting to buy.

Two offers, and they stack

5% off everything with code BF5. Valid from 10 November to 30 November 2026 on any order, with no minimum spend.

Free diamond studs on orders over $800 with code STUDS. Spend $800 or more and add our 0.24 carat round diamond studs in solid 18K gold to your bag, then enter the code at checkout to get them free. One pair per order.

Both codes can be used on the same order, and both work alongside our free worldwide shipping.

What is included

The whole Claratas collection is in the sale: engagement rings in every shape, tennis bracelets and necklaces, solitaire and halo pendants, stud and hoop earrings, eternity bands and wedding bands. Each design can be made with a lab grown diamond, a natural diamond or moissanite, in solid 9K to 18K yellow, white or rose gold.

Order early, because every piece is made to order

Nothing here sits in a warehouse. Your piece is handcrafted by our artisans in Bangkok once you order, which takes up to 6 business days, and delivery takes roughly 6 business days after that. If you are buying a Christmas gift or planning a proposal, ordering at the start of the sale rather than waiting for Cyber Monday gives your piece plenty of time to reach you.

Shipping, returns and certification

Shipping is free worldwide on every order, fully insured and tracked, with duties and taxes already paid. Returns are free within 30 days. Lab grown diamonds come with an IGI certificate, natural diamond solitaires with a GIA, IGI or SGL certificate, and moissanite with a GRA certificate.

Still deciding?

If you are shopping for a gift, our Christmas diamond gifts and gifts under $500 are good places to start. If you are planning to propose, see Christmas proposal engagement rings. Any questions, our FAQ covers sizing, timing and returns, or email contact@claratas.com.
