Can I Sell Diamonds Without Certificates?

Perhaps you lost your diamond's paperwork, or maybe you inherited a diamond and have no idea what its characteristics are. If you are in this situation, you may be wondering if you can sell diamonds without certificates.

The short answer is: yes. You have the following options available to you:

  1. Certify your diamond independently
  2. Get a jeweler's appraisal
  3. Sell your diamond without any certificates

Below we outline the advantages and disadvantages of both options for you.

However, the first and most important step is to confirm that your item is in fact a diamond. It is always beneficial for you to learn more about your item before you sell it.

Understanding the characteristics of your jewelry will make it easier for you to get an accurate quote for your item.

1. Certifying Your Diamond Independently

If you would like to certify your diamond, then we recommend you send the diamond to a reputable Gemological Laboratory such as the Gemological Institute of America (GIA) or European Gemological Laboratory (EGL USA).

These gemological laboratories analyze each diamond individually and grade according to their specifications, producing a grading certificate also known as a Diamond Grading Report.

The Advantages

A certificate will provide you with all the characteristics of your diamond. This will allow diamond buyers such as myGemma to be competitive when pricing your stone, as the certificate will eliminate any ambiguities about the stone, in turn offering you a more accurate price quote.

The Disadvantages

Depending on the laboratory you choose and the size of your diamond, the process can be quite costly (approximately $150) and take a minimum of 3 weeks, not including the time it takes to sell the stone.

It is always important to remember that obtaining a certificate does not guarantee an increase the value of your diamond, however it will allow you to get the most competitive price for your diamond.

A GIA-certificated diamond with an 'Excellent' cut grade can carry a premium of up to 30%. Upload your certificate here to get a price quote from myGemma: or contact us on +1 646 569 3655.

2. Getting A Jeweler's Appraisal

Jewelers can provide both written and verbal appraisals. An appraisal represents the Jewelers opinion of the stone's characteristics, usually providing an estimated retail value.

The Advantages

You can get an appraisal completed the same day in most areas of the country. An appraisal might reveal if the diamond has a lasered certificate number on it, which may mean it has been certified by a laboratory at some point, helping you to get more accurate assessment of your diamond.

An appraisal could also provide some guidance of the important characteristics of the diamond such as the carat weight, color and clarity. These characteristics are necessary for you to get comparable prices when shopping around. Having some documentation also allows the buyer to insure the item correctly during transit.

The Disadvantages

The information found on a jeweler's appraisal represents the opinion of that particular jeweler which may not align with the strict grading standards of the laboratories listed in our first article, myGemma or another diamond buyer.

An appraisal provides a New Replacement Value for insurance purposes, not a re-sale value. If the intention is to sell this item, keep in mind that this value will never be achieved when you come to sell the item.

Jewelry appraisals can cost around $100 or a percentage of the item’s value. The document will not increase the value of your item, but give you the information you need to market your item more accurately.
