Payment Terms


Ada Diamonds, Inc. accepts same-day bank wires, credit cards (Visa, Mastercard, American Express, and Discover), Bitcoin, and 12-month financing for U.S. residents in select states via Square and Affirm (up to $10,000 USD). Payments made by automated clearing house (ACH) or e-check are only allowed for deposits and are not valid for final invoice payments. Ada Diamonds does not accept personal checks or cashier's checks, even checks mailed directly from a customer's bank. For in-person sales at our San Francisco or New York locations, or at an Ada Diamonds' trunk show, cash is also accepted. Ada Diamonds uses three different online payment systems including Stripe, Square, and Intuit.  

Some transactions may require same-day bank wire as the only form of payment. You may be asked to provide government-issue photo identification at the time of payment. International clients may be required to show a copy of their passport in compliance with The USA Patriot Act. Ada Diamonds, Inc. reserves the right to reject a transaction for any reason, including but not limited to fraud risk, insufficient funds, or suspicious activity. 

Final invoices may only be paid via credit card or same-day bank wire transfers. In the case of bank wire, all payment fees are the responsibility of the customer.


In order to reserve a lab diamond, or begin the custom design process, a fully transferable, non-refundable deposit is required. Should you change your mind, the non-refundable deposit may be applied towards another diamond or piece of fine jewelry. This deposit is designed to show your seriousness towards completing a custom piece of fine jewelry with Ada Diamonds, and is also designed to discourage placing deposits on multiple stones at multiple retailers. Should you not be satisfied with your purchase, your non-refundable deposit may be fully refunded through our 30-day return policy on a finished piece of jewelry. Prior to the start of creating a bespoke piece, you will receive a cost estimate for the entire piece(s) of jewelry, which may require your signed approval.

Subsequent to placing a deposit on either a diamond or a piece of jewelry, your piece of jewelry must enter production or the remaining balance on the diamond be fully paid within 90 calendar days. In other words, it is not possible to place a deposit on a diamond and then wait several months to pay off the remaining balance of the diamond or jewelry. Ada Diamonds does not offer layaway.


Within 24 hours of placing a deposit on an in-stock or commissioned lab grown diamond, you may cancel your order and receive a full refund. After 24 hours, deposits are subject to the aforementioned refund policy.


Ada Diamonds purchases diamonds from major growers around the world, and our Diamond Concierges inspect each stone for quality prior to selling to a client. . A Concierge may need to bring in a diamond on memorandum for a specific client. While we aim to offer this as a complimentary service, Ada Diamonds may require a transferable, but non-refundable memo fee to bring in multiple stones for a single client request. Ada Diamonds will notify the client of this memo fee in writing prior to any transaction commencing. Memo periods can be limited to as little as 24 hours. Ada Diamonds cannot guarantee reservations of a stone without a 20% deposit.  


Due to the heavily bespoke nature of our pieces that are fabricated and hand-set in the United States, Ada Diamonds kindly asks our clients to respect the following jewelry order minimums: 

  • Proposal Settings and collection solitaires: $3,500 USD

  • All other bespoke engagement rings: $5,000 USD

  • Made to order fashion jewelry from our collections: $1,500 USD

  • Fully custom fashion jewelry: $2,500 USD

  • Collections' wedding bands: $1,500 USD

  • Fully custom wedding band: $2,500 USD

  • Polydiamond wedding bands: $1,500 USD

  • Custom cut lab grown diamonds: $7,500 USD

Our all metal wedding bands, Ready to Ship items, items from The Classics Collection, and loose diamond purchases carry no order minimum.


Due to unforeseen circumstances outside of Ada Diamonds’ control, the signature Lavoisier process has been suspended indefinitely. However, the commissioning of a diamond cut from an existing rough crystal is an available option. A larger deposit, up to the full cost of the stone, is required to begin the commissioning of a diamond or multiple diamonds. Deposits on commissioned lab grown diamonds are non-refundable and all commissioned diamond purchases are final sale.

Commissioned and custom cut diamonds are cut to client specifications. However, due to the nature of cutting gemstones from rough diamonds, Ada Diamonds reserves the right to adjust measurements and total carat weight within an industry-accepted variance yield of 10%. Commissioned stones may also be within 2-3 color and clarity gradings, which will be confirmed in writing prior to client payment. At this time, commissioned diamonds is not available for any fancy colored lab diamonds.


Shipments of loose diamonds, Ready to Ship items (including the Delicate Collection), and Strong Collection rings require full payment upon placing an order.

Prior to the shipment or delivery of a completed bespoke piece of jewelry, full payment on the remaining balance of an invoice is required. You have 45 days from production completion to pay your final invoice; however your piece of fine jewelry will not ship until the final invoice has been paid. Failure to pay for the finished piece of jewelry within 45 days of production completion may result in forfeiture of the deposit and cancellation of the order. Ada's 30-day return policy commences on the day of shipment to the customer (or date of pick up for local clients).


All prices quoted through the Concierge process, on Ada Diamonds' web site, at the San Francisco or New York locations, or at any trunk show are in USD unless otherwise noted. Ada Diamonds is not responsible for changes in foreign exchange rates and will only quote and charge clients in USD.


All purchases delivered in, picked up, or shipped to California addresses are subject to California sales tax at a rate of 8.5%. All purchases delivered in, picked up, or shipped to New York addresses are subject to New York sales tax at a rate of 8.875%. Due to the new Supreme Court ruling affecting internet businesses, your state may require sales tax be collected. Please consult with your Diamond Concierge for additional information.
