Interactive GIA Education Presentation
Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination.
What Is A Certificate?
A diamond certificate, also called a Diamond Grading Report, Diamond Dossier, or Diamond Quality Document, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A completed certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report.
MDC Diamonds Are Certified:

Every loose diamond sold by MDC has been analyzed and graded by one of the following gem labs.

       ♦  The Gemological Institute of America (GIA)
       ♦  The American Gem Society Laboratories (AGS)
       ♦  The European Gemological laboratory (EGL)
       ♦  The International Gemological Institution (IGI)

These laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry.

View Certificates While Shopping:
If you are interested in a specific certified diamond offered by MDC, you can view its certificate on our site before purchase. We offer a variety of grading reports and documentation:

       ♦  GIA Diamond Grading Report
       ♦  GIA Diamond Dossier
       ♦  AGS Diamond Quality Document

If you are interested in a diamond and a certificate is not available for viewing on the site, simply contact a diamond and jewelry consultant at service@mdcdiamonds.com or 1-866-239-4315.

Laser Inscription:

Many of our diamonds are laser inscribed with the certificate number on the girdle of the diamond, for your protection and peace of mind.

The process of using a micro-laser beam to etch a microscopic inscription onto the girdle of a diamond.

This number is only visible under magnification. All of our diamonds are shipped with their own original certificates and you can always be certain that the diamond you have is the same one described on the certificate with its matching unique number.

If a diamond is not laser inscribed you can request to have the certificate number to be inscribed on the girdle of the diamond by contacting a diamond and jewelry consultant at service@mdcdiamonds.com or 1-866-239-4315.

1,000 stars!

I contacted MDC just five days ago because my wedding is tomorrow and in the past two months we have received/returned two crooked and damaged custom claddagh rings from two different local jewelers near us. The website says to contact for rush orders and my wedding was only six days away so I decided I had nothing to lose to at least inquire. Moishy got back to me the same day (even though it was on a Sunday and not store hours) and managed to get my PERFECT claddagh ring to me the day before my wedding! I was beginning to get discouraged because the other two jewelry stores we went to really gave us the run-around and I nearly had to change our ceremony to exclude a ring exchange. I am so beyond grateful that they were able to rush my order and produce a flawless ring! Moishy is seriously a miracle-worker and I wish I could give them 1,000 stars! MDC has seriously made my special day perfect.
