We are the largest independent supplier of loose diamonds in the Northwest. Every single diamond at JDC is hand selected for their brilliance and value because industry standards (carat, cut, clarity and color) simply cannot define a stone's performance.
We reject over 95% of the diamonds we see because we look for stones that are bright and truly catch your eye - not just a certain size or statistics that look good on paper. That is why you won't find our diamonds listed online. Every diamond is different and perfoms in a way that is unique to that particular stone.
Our diamonds are ethically obtained and purchased directly from the source. We work with sources in Africa, Russia, Belgium, Canada and India to individually select every diamond we sell. Some diamonds can even be traced back to the exact location in the ground where they were discovered!
JDC has more diamonds to choose from then any other local jeweler. Plus you will enjoy the highest quality, best prices (starting as low as $100), and our unbeatable guarantee. Stop by and see for yourself!

The shape of the diamond is often confused with the cut. Though diamonds are cut to create different shapes, and different shapes may lend themselves to either brilliance or clarity, the term “cut” refers to the way light is reflected throughout the individual stone through its facet arrangement. Choose the shape that you like based on your style and you cannot go wrong.
The cut of a diamond determines its brilliance or sparkle. Each shape will be cut differently. Before a diamond is cut, the location of inclusions and flaws, the natural coloration, and the original shape of the rough stone are studied extensively. The stone facets are then mapped out and cut in a way that maximizes size, shape, and clarity. For optimal light performance and rarity, you will want a diamond that is cut neither too shallow nor too deep.
Color refers to the natural body color of a diamond. Diamonds with less color allow more light to pass, releasing more brilliance and fire. The scale runs from D (colorless) to Z (light yellow). The less color a diamond exhibits, the higher the rarity, and therefore the higher the value. Although some people prefer warmer toned diamonds, especially when being placed in yellow or rose gold settings.
A diamond is distinguished by its natural characteristics, just as a person would be noted for her blue eyes or his brown hair. Notated as a diamond's clarity, these characteristics can be present on the surface (blemishes) or within the stone (inclusions). The clarity is judged by the number and types of these characteristics and is designated using a scale that runs from Fl, defined as flawless, to I3, defined as inclusions visible with the naked eye. A flawless diamond is truly rare.

The unit of measure used for the weight of a diamond is the carat. As a matter of reference, a carat is equivalent to .2 grams or .007 of an ounce. Carat weight can also be divided further by using points. There are 100 points in one carat. So a 1/4 (.25) carat stone can also be expressed as 25 points and mean exactly the same thing. When comparing two diamonds, please note that just because one is twice the carat weight of the other does not mean that it will appear to be twice the size.
