Frequently Asked Questions

Are Lab Diamonds Less Expensive?

Much like mined diamonds, lab diamonds are priced based on their 4Cs characteristics. Lab diamonds are typically 30-40% less expensive than natural diamonds of the same size and quality.

Why Doesn't Ada Publicly List Diamonds?

Unlike other online retailers, we do not list our inventory publicly. Why?

  1. Navigating through a database of thousands of diamonds is a difficult, intimidating, and sterile experience. You deserve better.

  2. Our expert gemologists use criteria beyond the 4Cs to curate a list of diamonds tailored to your specific inquiry.

  3. We are proud diamond snobs. We refuse to offer you mediocre diamonds.

Can I Resell a Lab Grown Diamond?

Yes, there is a resale market for lab grown diamonds. Just like a mined diamond, a lab diamond is also forever and will always have a resale value. In fact, Ada Diamonds purchases lab diamonds directly from the public through our Public Purchase Program.

Ada Diamonds offers a lifetime trade-up policy if you desire to increase the size of your diamond(s) at a later date.

Why Should I Choose a Lab Diamond?

Known Ethical Origin: By refusing to use mined diamonds in our jewelry, we can guarantee that all the diamonds we offer are conflict free and in no way connected to the dubious diamond trade that continues to flourish to this day. Learn More.

A Cleaner Purchase: The extraction of diamonds from the earth is fossil fuel intensive, environmentally damaging, and becoming less sustainable every year. Growing diamonds uses a fraction of that energy and does not contaminate fragile ecosystems in rivers and lakes. Learn More.

Superior Quality & Size: Ada’s clients typically are able to achieve a 30% larger carat weight in lab grown over a comparable mined diamond of the same quality. Want a diamond you can be proud of? Lab grown offers the ability to go from unexceptional to extraordinary, carat for carat, price for price.

Can a Jeweler Tell the Difference?

No, a jeweler cannot tell the difference between lab grown diamonds and mined diamonds, because they’re both diamonds! They have the exact same chemical and optical properties.

Ada Diamonds is proud of the origin of cultured diamonds. All diamonds above 0.50ct are microscopically laser inscribed by third party grading organizations with a unique ID number and the letters ‘LG’ indicating the diamond is lab grown.

See for yourself! A CNBC reporter recently took an Ada Diamonds engagement ring to jewelers in NYC and “not a single jeweler could tell that it was lab grown.”
