The purchase of diamond engagement ring is likely one of the most time-intensive and difficult purchases you'll ever make. It can be a challenge to know exactly what your loved one wants without ruining the surprise of an engagement.  

We will gladly set a diamond that you purchase from Ada into a temporary proposal setting so that you can surprise your loved one with a ready-to-wear solitaire engagement ring with the intent to build your dream ring together. The cost of the proposal setting can be applied in full to a new setting. Simply send back your ring for re-setting after finalizing your new design with our friendly concierge.

All of Ada's solitaires are fully bespoke and made to order, so should you decide to stick with your proposal setting forever, we'll make sure it's exactly what you want. If you'd like to modify one of our existing solitaires to meet your design preference, that's no problem. We're happy to help!


Available Proposal Settings


Pricing for solitaires is simple and straightforward: 14kt white, yellow, and rose gold are $650 USD; 18kt white, yellow and rose gold is $750 USD; Platinum is $1,000 USD. To ease with the purchase a diamond and proposal setting, we have partnered with Silicon Valley financier Affirm to offer you a flexible way of financing your purchase over time with no hidden fees. Buy loose diamonds for a proposal setting with Affirm and pay off your purchase in easy, fixed payments over 3, 6, or 12 months at rates from 10-30% APR. 

Grown From Love

Ada also offers something truly extraordinary as part of our Lavoisier Process: you can commission the cutting of two diamond gemstones from a single rough diamond. Ada will take these two bespoke diamonds, cut from the same cloth, and make complementary rings for you and your loved one that are forever be linked: separate rings but the same diamond.
