Proposal Settings

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.


Grown From Love

Ada Diamonds cultures diamonds from donor carbon, provided by you. We can process and purify any carbon-containing items — flowers from your wedding, graduation keepsakes, excess materials from a house remodel — into pure diamond, making for the ultimate in meaningful, custom jewelry. We would love to celebrate your finest moments and memories with a commissioned diamond.

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.
