Carat is the unit used to measure the weight of a diamond. Carat weight and size are related, but not always perfectly correlated. Different carat weight proportions may vary for different shapes. 1 carat is equal to 200 milligrams (0.2 grams).

The quality of a diamond’s cut is what ultimately determines the brilliance and fire (sparkle) of a diamond. The cut involves the proportions, symmetry, and polish, which control how much light reflects and refracts within the diamond. The more precise the overall cut is, the more sparkle the diamond will give as a result of light performance.

Color is the unchangeable natural color present in a diamond. The brilliance (light and dark brightness) and fire (reflected spectrum of colors) is best emitted from the most colorless diamonds.

Clarity refers to the level of internal and external purity of a diamond. Impurities, or inclusions, are like little birthmarks, usually only noticed when under a microscope. They are caused by minor chemical blips that occur during the diamond’s formation. Very rarely do inclusions affect the beauty or structure of a diamond.

Symmetry refers to the exactness of the shape of a diamond, specifically the symmetrical arrangement and exact placement of the facets. Symmetry is a portion of the overall cut grade.

Polish refers to the quality of the diamond’s surface regarding the polishing process and blemishes that occur during the cutting of the diamond. These blemishes are only on the surface and do not affect the inside of the diamond. Polish is a portion of the diamond’s overall cut grade.

Sometimes known as the fifth “C” of diamond buying, a diamond certificate is created by an independent laboratory staffed by experienced, professional gemologists who specialize in evaluating diamonds. During this evaluation, a series of tests and tools will be used to analyze the diamond’s cut, color, clarity, carat weight, dimensions, polish, symmetry, and more. These unbiased findings are detailed in the certificate. Joseph Jewelry does not sell uncertified diamonds.

Table %

The table is the flat facet on the top of a diamond’s surface--the part you will be looking at when it is set in your ring. The table determines how much light is let into the diamond as well as how it is dispersed to the other facets, creating sparkle. It should be balanced; not too wide and not too narrow. The ideal table size range depends on the shape of the diamond.

Depth %

Depth is the measurement from top to bottom, from table to culet. It is expressed as a percentage: the diamond’s total height divided by total width. The beauty of a diamond’s light performance depends on ideal proportions, which is why depth is important. It should not be too deep or shallow. The ideal depth range depends on the shape.

Fluorescence causes a diamond to look hazy, dull, or milky under UV lights, such as sunlight or blacklight. This can severely inhibit the sparkle of the diamond. Joseph Jewelry primarily carries diamonds with no fluorescence. If you have unique preferences, please contact one of our designers.
