Ada Diamonds is a leading luxury purveyor of lab grown diamonds, specializing in large, sensational cultured diamonds of superlative quality.

A Concierge is ready to curate a list of lab diamonds unique to your inquiry!

"Are lab grown diamonds less expensive than mined?" For the most part, the answer is yes! Ada 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 in price. For simplicity, Ada has developed four quality levels:

Premium, Recommended, Satisfactory & Unexceptional


Consider this general pricing ranges of Ada's 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. 

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

We choose to not publish our available inventory because:

  1. We are diamond snobs and take pride in delivering superlative curation services. We refuse to offer our clients mediocre diamonds, ever.

  2. There are criteria beyond the 4Cs that define the quality of a diamond. Our expert gemologists use that information to curate a unique list 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.
