What’s the difference between Ideal Cut, Premium Cut, etc. grades:  The terms "Premium Cut", "Tolkowsky Ideal Cut", and "Excellent Ideal Cut" apply only to round diamonds. Stones receive these grades according to certain angle and percentage standards. For example, Premium Cuts have a table percentage from 58.0% to 61.0%, Tolkowsky Ideal Cuts have a table percentage from 53.0% to 58.0%, and Excellent Ideal Cuts have a table percentage from 52.5% to 58.4%.  Depth percentages on any of them should not be below 58.0% or above 63.8%.

Does the cut of the diamond have any effect on the price:  At The Diamond Source USA we only sell the finest cuts of diamonds and the price does not change according to cut.

Can I see the difference from one color or clarity grade to the next:  The brilliance of a diamond is determined by the quality of its cut -- not its color or clarity. When cut properly it is very difficult to see the difference between two-color grades, F-G, G-H, etc., if the stones are faced up. In clarity, from the grade of SI2 and up, normally one can not see anything in the diamond with the naked eye.  Therefore clarity has to be determined by the use of a 10x loupe.

What is fluorescence, and how does it affect a diamond:  Fluorescence is an emission of light from within a diamond and can occur naturally.  To detect it a "black" or UV (ultraviolet) light must be used.  Yellow fluorescence and in some cases strong blue fluorescence may make a diamond appear cloudy or milky, even under daylight.  In "lower" colors (I and below) some blue fluorescence may help the diamond to appear whiter than it technically is.  Fluorescence information is always available on the certificate.

Why are there no A, B, or C color grades:  In order to avoid confusion with a multitude of differing, previously existing grading systems, the GIA (Gemological Institute of America) system was created, and "D" was designated the highest color grade.  This system is now recognized world-wide.

What is the cost of shipping: All items are shipped via Federal Express insured overnight shipping and the cost is determined by the dollar amount/value of the piece. Ask your sales associate for further details.

How do I know I’m getting what I bought:  All the diamonds we sell that are .5 carat and above are certified by the GIA (Gemological Institute of America) laboratory. Therefore, each diamonds has been graded, registered and plotted. By comparing the diamond against the original certificate that is shipped with the diamond, any reputable diamond appraiser can verify that the diamond is the one identified by the certificate.

What kind of guarantee do you offer:  Since all diamonds are certified, the guarantee is in the certification. If the diamond is mounted in a ring, earring, etc., and since we have no control over how it is handled once it leaves our office, we highly recommend that the item be insured through your personal insurance company.

Does The Diamond Source USA maintain its own inventory:  Yes!  We sell diamonds from our own inventory.  We do not list "virtual" stones, or act as an intermediary between you and another diamond company.  Our inventory is always changing, and this is the reason for our "Request a Diamond" system.  You tell us what you would like, and we will respond with information about the diamonds we have which most closely match your request.

Where do you get your diamonds:  The rough comes mostly from Africa and Russia. Once we receive it, it is cut at the factory and then imported and made available to sell.

What’s a Certified Diamond:  A certified diamond is a diamond that has been weighed, measured, color graded and its cut determined at a major laboratory by individuals trained only in diamonds. Many of them hold degrees in appropriate areas. These individuals grade and certify daily as a profession.

What’s an Appraisal:  Once the diamond is certified, knowing the weight, color, cut and clarity, the stone can be "appraised". An appraisal gives the diamond a retail value or replacement value. An Appraiser does this. Some appraisers also certify diamonds "to GIA (Gemological Institute of America) standards". This is done when the diamond has not been certified at a major laboratory. We recommend that you purchase only laboratory-certified diamonds, certified by full-time professional graders.

Does The Diamond Source USA ever have a sale:  Unlike fashion clothing, diamonds never go out of style. Most clothing stores will run sales at the end of the season to get rid of that season’s fashions and make room for the new season. Some things always go out of style, but diamonds are always in fashion. A "sale" is just another retailer gimmick to make you think you are getting a good deal. At The Diamond Source USA, all of our prices published in our "Diamond Buying Guide" are already at the lowest price. There is no guesswork. The price you see is the price you pay. No gimmicks! Don’t be fooled – be prepared.
