Return Policy

Your Diamond Concierge will go above and beyond to ensure you are fully satisfied with your purchase. Should you be unhappy for any reason, Ada Diamonds is proud to honor a full 30-day return and refund policy. To initiate a return, submit a Customer Service Inquiry within 30 days of receipt of Ada merchandise through the website. Merchandise may be returned in person at the Sunnyvale or San Francisco locations by appointment or during our drop-in hours. Clients will be responsible for shipping, fully insured and double boxed, all returned merchandise back to Ada Diamonds through Fedex or UPS with receipt. Depending on value, Ada Diamonds may arrange for armored shipment, and will deduct any costs associated from total amount of refund. International clients are responsible for paying for, and fully insuring, return shipments. Any import tariff, taxes, or duties assessed and charged on return of goods to Ada Diamonds will be deducted from total amount of refund.

Finished jewelry must be returned in like new condition with original grading certificates, if applicable. Loose diamonds must be returned with the original grading certificate and in their original condition. Ada Diamonds will check to ensure both loose diamonds and set diamonds match their corresponding grading certificates. Once your return is received and confirmed, refund will be processed in 5-7 business days.

Returned items may not be eligible for immediate re-purchase. 


Any commissioned diamonds, including Ada's signature Lavoisier Diamonds, are not eligible for return.

Any additional services such as secondary third-party gemological grading, engraving fees, or re-setting fees are not refundable. 

Eternity bands are also not eligible for full return and refund. Bands that cannot be re-sized may be exchanged within 30 days of purchase for a different size, minus the following re-stocking fees: $400 for 14kt or 18kt gold, $500 for platinum. 

Ada Diamonds reserves the right to revoke a 30-day return policy for any order with which pre-payment prior notice has been given to a client. For example, if a client wishes to purchase a lab grown diamond outside of the quality levels approved by Ada Diamonds, or has been advised of potential issues in fabrication of a piece, Ada Diamonds reserves the right to revoke the return policy, so long as this notice has been given prior to a client paying any part of an invoice or deposit. 


Solitaire engagement rings, as noted by a Diamond Concierge, are eligible for Ada's Proposal Setting policy. Proposal Settings may be returned within 18 months of purchase for re-setting by Ada Diamonds. The entire cost of the original setting may be applied toward the purchase of a new setting. The new setting must be of at least equal or higher value than the original setting.


Ada Diamonds is pleased to offer complimentary engraving up to 20 characters at the time of manufacture. Any engraving done after manufacture will carry a $25 fee. Ada Diamonds does not recommend engraving in rings for which a final size is not known.


From time to time, an engagement or wedding ring purchased from Ada may need to be re-sized. SF bay area residents are welcome to drop off a ring for re-sizing at either the Sunnyvale or San Francisco at no charge. For those outside of the SF bay area, a re-sizing fee of $50 will be required, which covers fully-insured shipping both ways. In the event a ring must be completely re-cast due to significant incorrect ring size (2+ sizes), a fee of $250 will be applied.


Strong Collection rings must be exchanged for a different size ring within 30 days of receipt. Eternity bands, and those rings for which a Concierge has provided pre-payment notice of inability to re-size, are ineligible for complimentary re-sizing and will require full exchange within 30 days. Due to the bespoke nature of Ada's eternity bands, re-stocking fees for eternity bands are as follows: $400 for 14kt or 18kt, $500 for platinum. 

Please note that all Strong Collection and Eternity Band exchanges that require different sizes will NOT be the same ring, but rather will be a replacement ring. Those looking to ensure the ring included in their nuptial ceremony remain their eternal rings are encouraged to consider non-Strong Collection and non-eternity bands that can be re-sized rather than replaced.
