ARE DU LYON GEMSTONES CERTIFIED?

All of the gemstones individually listed in our collection are accompanied by a Du Lyon gemstone report.  In addition, a gemological certificate, issued by an independent laboratory, if not already supplied with the stone, can be purchased (at additional cost) for any of the gemstones in our collection.  Du Lyon will typically send gemstones to be graded by the laboratories of the Gemological Institute of America (GIA) or the American Gem Trade Association (AGTA), two of the most widely respected and recognized independent gemological laboratories in the world.

WHAT IS AN INDEPENDENT LABORATORY CERTIFICATION?

Du Lyon now offers independent laboratory gemological certificates for any gemstone individually listed in our collection.  These certificates are gemstone identification reports issued by a respected, independent gem lab that certify the gem type, size, color and whether it is natural or synthetic.  At times they may identify certain gem treatments (such as fracture filling of rubies) but they are not grading reports for clarity or value and will not identify the country of origin.

Please note that a gemstone certificate is NOT a detailed evaluation of a gemstones quality.  A more complete, gemstone grading report that essentially serves as a unique "fingerprint" for the stone and helps validate a gemstones identity and value is available but at a much higher cost.  We generally only recommend this option for Investment gemstones.  If you are interested in obtaining a gemstone grading report please contact us at customer_care@dulyon.com for more details.

HOW DO I PURCHASE AN INDEPENDENT LAB CERTIFICATE FOR A GEMSTONE?

You will have the option to add a gemological certificate when you add a gemstone from our collection to your shopping cart and please be aware that if you need a certificate, you must order it at the same time you place the order for the gem.  Once we receive your order we will send your gem to an independent gemological laboratory for testing.  It will take the lab between 4 days and 2 weeks to issue the certificate and in addition, there will be 4 days shipping time so your order will be delayed by 8 to 18 days.  The gemstone will be shipped to and from the lab via Priority mail, insured for the full value of the gemstone and these shipping costs will be added to your order.  Shipping costs can be determined here:

Please Note: While a gemstone can be returned to Du Lyon, all costs associated with obtaining a gemological certificate are non-refundable.
