Make your own art from our diamonds

There are a variety of reasons that you might want to purchase loose diamonds. You might have a custom designer that you've worked with for years. Perhaps you are looking to upgrade or replace a stone in your engagement ring.

Whatever your reasons, our Diamond Concierges are delighted to help you purchase fabulous lab-grown diamonds in sizes ranging from 0.01 to 5 carats, in an array of shapes, and in virtually every color in the rainbow. After you submit the contact information below, an Ada Concierge will filter through our inventory of thousands of diamonds and provide you with a curated list, to help you find the exact gemstone(s) that fits your fancy. Ada can even commission the growth, cutting, and polishing of loose diamonds to you exact specifications.

We often get asked "are lab grown diamonds less expensive than mined?" For the most part, the answer is yes! Ada Diamonds curates from a selection of nearly every lab grown diamond available in the world. That allows us to offer the best of the best, without compromise.

Much like mined diamonds, lab grown diamonds are priced based on their quality characteristics. For simplicity, Ada has broken down these quality levels into four categories: Premium, Recommended, Satisfactory, and Unexceptional (beneath Ada's standards). All of Ada's white diamonds are optimized for cut and brightness, will be eye clean (no visible inclusions to the naked eye), absent fluorescence, and of exceptional quality. If we wouldn't wear it, we won't recommend it.
