Benefits of Ada Diamonds

Benefits of Ada Diamonds

As a luxury custom jeweler of lab diamonds, Ada Diamonds is proud to offer our clients exclusive benefits including a robust jewelry warranty, lifetime trade-in, guaranteed diamond resale, free shipping, and 30-day returns.

Jewelry Warranty & Re-Size


Warranty & Maintenance

  • Complimentary repairs and replacement of accent diamonds within the first two years.
  • Not applicable in cases of negligence, heavy wear, or major impact. Paid repairs may be available.
  • Work performed by any other jeweler voids warranty.

Clients are welcome to make an appointment to drop off their Ada fine jewelry at either our SF or NY showrooms for complimentary cleaning, polish, and re-plating. Clients not local to SF or NY may pay a $50 fee for fully insured round-trip shipping.

Complimentary Re-Size

Eligible rings qualify for complimentary, one-time re-size. Most re-size jobs can be completed in 2-3 days. Additional re-sizes may be done for a fee, but are discouraged in order to preserve the integrity of your Ada jewelry.

Trade-In & Resale

Lifetime Trade-In

Trade-in isn't just about upgrades. Whether you want to change the shape or size of your diamond after your purchase, or you are ready to upgrade to a more expensive diamond, Ada's trade-in policy is designed with clients in mind.

  • Your lab diamond must be IGI, GCAL, or GIA-certified.
  • You will receive credit equal to 100% of the original price toward the purchase of a new diamond on trade-in.
  • The price of your new diamond must be 1.5x the price of your original diamond.
  • Diamonds purchased from Ada within 90 days may be eligible for an exception to the 1.5x price increase requirement. These trade-in's are handled on a case by case basis.
  • Your diamond must be in its original condition with the original diamond grading report.
  • Lifetime trade-in does not apply to the cost of the setting.

Buy-Back Program

Should you no longer want or need your lab diamond, Ada Diamonds is proud to offer a Buy-Back Program. Through this program, we buy independently certified lab diamonds previously sold to Ada clients. We are so confident in the lab diamonds we sell, we guarantee to take them back!


Proposal Settings


Not sure what your sweetheart desires? Select solitaire engagement ring settings are eligible for Ada's Proposal Setting Program. Proposal Settings may be exchanged 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 with no additional re-setting fee.


Financing & Payments

Deposits & Final Payment

In order to reserve a diamond or piece of fine jewelry, a 20% transferable deposit is required to enter our bespoke design phase. This deposit is considered non-refundable and designed to show seriousness toward moving forward with Ada Diamonds. Deposits may be transferred to another diamond should you change your mind. The remaining balance is not due until the piece of fine jewelry has been finished and passed our strict quality assurance check. All pieces of jewelry must be paid in full prior to shipping.

Payment Methods

Ada Diamonds accepts all major credit cards, bank wire, and Bitcoin. Cash is accepted in person at one of our showrooms. We offer financing through Affirm. Ada Diamonds does not accept ACH, check, or money orders. All prices are in US dollars.
