Purchase Lab Grown Diamonds

Brighten your world with stunning, sustainably created diamonds of superlative quality.


Ada Diamonds proudly refuses to sell unexceptional diamonds. All of our diamonds are of the highest purity and optimally cut for maximum light performance. Every diamond we sell is 'eye clean,' meaning it contains no inclusions that are visible to the naked eye. In other words, a diamond purchased from Ada Diamonds is guaranteed have superlative fire, scintillation, and brilliance. 

We often get asked "Are lab grown diamonds less expensive than mined?" For the most part, the answer is yes! Ada Diamonds offers lab created diamonds at about a 30-40% discount compared to mined diamonds of the same quality.

Much like mined diamonds, lab grown diamonds are priced based on their quality characteristics and can vary dramatically in price. For simplicity, Ada has developed four quality levels for cultured diamonds:

Premium, Recommended, Satisfactory & Unexceptional


Consider this general pricing ranges of Ada's three quality levels. This chart is for round brilliant, white diamonds. Fancy shaped diamonds and fancy colored diamonds of the same quality and carat weight can vary in price slightly.

All prices shown are in USD. If the perfect stone for you is not in our inventory, Ada can commission the growth, cutting, and polishing of diamonds to your desired specification. For five carat and larger diamonds, please inquire.

Why We Don't Publicly List Diamonds

Ada chooses to not publish our available inventory for a few reasons:

  1. We are diamond snobs. We refuse to offer our clients mediocre diamonds, ever. We take great pride in delivering superlative service and spectacular diamonds.
  2. There are criteria beyond the 4Cs that define the quality of a diamond. Our expert gemologists use that information to curate lists of beautiful diamonds for each client.
  3. Navigating through thousands of diamonds is a difficult, intimidating experience for someone without gemological training.
  4. Choosing a diamond from a spreadsheet is a sterile, suboptimal experience. You deserve better.
