Payment & Shipping


Once your piece of jewelry is completed, you may pay via credit card, bank wire, or financing with Affirm. Clients who pick up in our SF, NY, or ATX showrooms may pay with cash.

Your order ships in a beautiful Ada Diamonds jewelry box along with non-toxic jewelry cleaner and a travel pouch. We are able to ship to 70 countries fully insured. We ship via complimentary Fedex Two-Day or Overnight Priority in the USA and via Fedex International Priority for international orders. We recommend shipping your order to a business or having it held at a Fedex Office for secure pick up.

International clients are responsible for all import, taxes, duties, and fees associated with their order. 

Satisfaction Guaranteed

We fully expect you to love your Ada Diamonds jewelry. If for any reason you don’t, return your piece of jewelry within 30 days for a refund, less any non-refundable deposits or re-stocking fes. Finished jewelry must be returned in complete, original, out-of-the-box condition, with original grading certificates, if applicable.  

Want to see the diamond first? Simply pay for the diamond in full and we will ship to an address of your choosing. If you’d like us to the set the diamond for you, we will send you a return label to return the diamond to us for setting. No longer interested? Return the diamond for a full refund within 30 days.

Jewelry Warranty

Within the first two years of purchase, we will replace side or accent diamonds (of 0.25ct and smaller) that go missing if due to a manufacturing defect or light wear and tear. Our warranty excludes coverage due to negligence. Should we determine the repair needed is outside of the warranty coverage, we are happy to provide a quote for paid repair.  

All cleanings, polishing, plating requests, and re-sizes are complimentary in our SF, NY, and ATX showrooms. Not local to SF or NY? A shipping fee of $50 USD covers fully insured shipping both ways. Re-sizes typically require 2-4 business days.

Trade-In & Re-Sale


Should you want to upgrade your Ada diamond later on, you can receive the full value of what you paid toward the purchase of a new lab diamond, for life. The new lab diamond must be 1.5x the cost of your original diamond to receive full trade-in credit.

No longer want or need your lab diamond? Clients of Ada Diamonds are guaranteed to receive a financial offer for their diamond through our Buy-Back Program.
