When you sell a loose diamond with Worthy, you can be confident that you will get the most the market can offer. We ensure this guarantee by having your diamond graded by GIA prior to the auction.

GIA, or the Gemological Institute of America, is the industry’s leading grading lab that established the diamond grading system and continues to raise industry grading standards. Because they are so well-reputed, a GIA-graded diamond is usually worth more, and diamond buyers are usually willing to pay more for it.

When your diamond arrives at our headquarters, we will photograph it in high-definition then one of our professional handlers will personally deliver it to the GIA labs nearby. When the evaluation is complete, we will pick up your diamond and store it in our highly secure safe for the duration of the auction.

You will also receive a complimentary, printable e-diamond grading report with the option to purchase the hardcopy in the event that a deal is not met.

At the end of the day, our goal is to provide a safe, transparent, and satisfactory experience. The complimentary gradings at GIA are just one of the ways we do this.

Get The Highest Offer When Selling Loose Diamonds

Loose diamonds, especially large, well-cut examples, are highly prized by many of the professional jewelers and collectors who are part of our buyers network. Many newly mined diamonds are marred by political conflict or are associated with environmental damage, and our buyers have clients who want jewelry made with conflict-free diamonds.

Even in the conflict-free diamond industry, large, high-quality rough diamonds have become more expensive to mine, as well as more difficult to find. The demand for loose diamonds is high despite these problems, ensuring that quality stones remain hot commodities.

What Factors Can Affect The Value Of Loose Diamonds

The amount of money you’ll receive when you sell loose diamonds with Worthy varies greatly depending on a number of factors. These include:

  • Diamond Carat: The larger the stone, the greater the value, in most cases.
  • Diamond Color: Colors vary from colorless to colored; loose colored diamonds have an evaluation scale all their own.
  • Diamond Clarity: The fewer blemishes or flaws it has, the clearer and more valuable a diamond is likely to be.
  • Diamond Cut: A diamond’s shape can make it more valuable, as can the quality of the cut.
  • Diamond Inclusions: Inclusions, or flaws, are not always undesirable. Some inclusions help to identify diamonds, in the same way your fingerprints help to identify you.
  • Diamond Grading: A grading report from GIA or GSI helps to prove authenticity and increase buyer trust.

Don’t worry if you have lost your proof of purchase, don’t know what clarity or color your diamond is, or haven’t had your diamond certified. Worthy’s evaluation process includes independent certification by top gemological experts. We’ll make sure you know all this information about your loose diamonds before putting them up for auction.
