Gemological Terms & Laboratory Info
What is a gemologist?
A gemologist is an individual who graduated from studies in identification and grading of diamonds and gemstones at a recognized gemological institute. Most graduate gemologists in the United States have studied at the Gemological Institute of America (GIA). They earn the prestigious Graduate Gemologist Diploma.
Do you have gemologists on staff to help me with my purchase?
Yes, you can speak with one of our certified gemologists in our New York or Los Angeles offices at any time. They are an important part of our customer service team.
How do I know I will receive what I ordered?
We send a professionally prepared and independently created laboratory report from International Gemological Appraisers (IGA) with each shipped diamond. This diamond certificate can be reviewed by any gemologist and analyzed for the unique characteristics of your individual diamond.
What are the IGA certificates?
Each uniquely created certificate details the peculiar characteristic of your diamond after it has been carefully examined. These certificates contain a universally understood method of communication of diamond qualities and adhere to the highest standards of diamond grading. An IGA diamond certificate is included with your loose diamond or diamond jewelry purchase.
Just what are the 4Cs of diamonds?
The 4Cs are the universally accepted grading standard created by Gemological Institute of America (GIA). Every diamond is graded by Cut, Carat, Color and Clarity.
I’ve heard the term, Eye Clean referring to a diamond. Just what is that?
This is a diamond trade specific term indicating the diamond is clean or free from noticeable inclusions to the unaided eye; face up, from a distance of twelve to fifteen inches. VS2 or higher quality diamonds are usually eye-clean. SI1, SI2, and I1 diamonds must be carefully inspected to locate visible inclusions from the top of the stone.
What does the term “Cut” mean?
Some people think the cut is the shape, like round or oval. But it actually refers to how well cut the stone is. Well cut diamonds appear fiery and brilliant. Poorly cut stones are dull and unappealing. A well cut diamond can actually make the stone appear larger than poorly cut diamonds of the same carat weight. So you can see how important the cut grade is.
Do you sell synthetic diamonds?
No, every diamond appearing on our website for sale is a natural earth-mined stone.

Clarity Enhanced Diamonds
What are enhanced diamonds and do you sell them?
Diamonds can be enhanced or treated in a number of ways. The goal generally is to improve clarity and therefore its beauty. We do sell treated diamonds. But all of our diamonds are naturally earth mined including the clarity enhanced diamonds. You can and should request a copy of your diamonds’ certification at the time of purchase.
How are diamonds clarity enhanced?
We use technologically advanced laser enhancing and filling. No visible trace of the enhancement process remains, and no carat weight is added. These enhanced diamonds are 100% natural diamonds that are genuine but with improved clarity. The diamonds’ clarity and quality improves but with a lower price than non-enhanced diamonds of similar clarity grade.
