Ada Diamonds Lab Diamond Buy-Back Program
If you purchased a lab diamond from Ada Diamonds and would like to sell it to us, you may submit it for buy-back. We specifically seek to buy back lab diamonds meeting this criteria:
- Carat Weight: 1 carat or larger
- Color: D, E, F, G
- Clarity: VS2 or better
- Independent Certification: IGI, GCAL, AGS, GIA (full fidelity grades only)
- Date of Purchase: More than 30 days ago
Ada Diamonds does not purchase any precious metals, ungraded lab grown diamonds, natural (mined) diamonds, or any other gemstones such as sapphires, rubies, or emeralds. Sellers must own the lab created diamond and provide unaltered, unredacted, itemized proof of purchase from Ada Diamonds. Appraisals are not accepted in lieu of an invoice or receipt. Sellers must be U.S. residents acting in a personal capacity.
The Buy-Back Program is only for serious sellers ready to complete a transaction immediately. If you are unsure whether or not you want to sell your lab diamond or simply curious to see what you could get for your lab diamond at some point in the future, we do not recommend receiving an offer, as it will expire and will not be eligible for renewal. If you were the recipient, but not the purchaser of the lab diamond, you may be required to show additional documentation from the purchaser, such as a photo ID.
If you are a lab diamond wholesaler seeking to work with Ada Diamonds, please email us at firstname.lastname@example.org.
Please note— Ada Diamonds only seeks to purchase lab diamonds originally purchased from Ada that match the criteria outlined above. If your submission is incomplete, if your diamond was purchased from another retailer, or if your diamond does not meet our criteria, we will not respond to your inquiry.
Why We Decided to End the Public Purchase Program
When we first launched our Public Purchase Program, the primary goal of growers around the world was to offer lab diamonds that rivaled the world’s best natural diamonds. Lab diamonds inherently have a higher purity (Type IIa) than 98% of natural diamonds with a brighter, whiter appearance. For years, we struggled to source adequate supply from the market to fulfill consumer demand.
Since interest in the lab diamond market has exploded, the majority of lab diamonds being produced in recent years are of inferior quality to our standards, often grown with sped up methods and offered to the public at steep discounts. These lab diamonds possess negative quality characteristics beyond the 4 c’s such as color tinges and blurry material that make them undesirable to an Ada Diamonds client. This has made it nearly impossible for us to pass through our strict quality control lab diamonds purchased elsewhere, especially budget e-commerce retailers.
As a result, we are redirecting our efforts and resources towards sourcing exclusively the finest lab diamonds for our valued clients. As part of that commitment, we have limited our purchasing to our Ada Diamonds Buy-Back Program, offered exclusively to our clients who purchase an independently graded laboratory grown diamond of 1 carat or larger from us in the past. In this way, we know that any lab diamond offered to us for sale is one we have already passed through our strict standards and would happily stand behind, again.
