The decision to propose is one of, if not the, most important decisions of your life, often made more stressful by the time-intensive, confusing, and difficult process of purchasing an engagement ring.

It can be difficult to find a trustworthy, competent jeweler, or daunting to sort through a website with a list of 10,000+ diamonds and purchase one sight unseen. And good luck if you want your proposal to be a surprise! 

Ada Diamonds solves all of these challenges. We proudly refuse to work with 'dirt diamonds' and guarantee that all diamonds we sell, large and small, are cultivated above the Earth, not mined out of the Earth.

We refuse to allow customers to purchase via our website from our available inventory of 10,000+ diamonds. Instead, we work with our clients via our innovative Diamond Concierge Service, where a knowledgeable, yet approachable, diamond expert patiently answers all of your questions, prepares a curated list of diamonds that match your interest (and budget), supports you all the way through the choosing of the perfect diamond, and ensures that the jewelry Ada custom fabricates for you is of the highest quality.

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. 

After the proposal, you and your partner can build your dream ring together as a team. The cost of the proposal setting can be applied in full to your new setting. Simply send back your ring for re-setting after finalizing your new design with your Diamond Concierge. This free re-set is a service we are honored to provide our clients. 

Should you decide to stick with your proposal setting forever, you can rest assured that your engagement ring will last a lifetime as all of Ada's engagement rings are custom made to order in the United States by award winning fabricators.

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.
