Diamond Cut
Of all the variables affecting the value of a diamond, the cut is the most crucial. A "diamond in the rough" looks like a cloudy pebble until a skilled diamond cutter cuts it in the precise proportions that bring out the brilliance and reflect a rich rainbow of colors. Without cutting, even a flawless, colorless diamond would have no sparkle. Cut refers to both the shape of the diamond and the arrangement of its facets. In a well-cut diamond the light plays off the facet to show a display of brilliance and fire. If the cut is too deep or too shallow, light will spill out through the side or bottom and be lost, resulting in a less brilliant display and thus, a less valuable diamond. Cut can make a large difference in the price of two diamonds of the same color and clarity.
Light Handling Properties of a Diamond
Cut so that the light is reflected back through the top of the stone
Too Deep; allowing light to escape through side
Too Shallow; allowing light to escape from the bottom

Diamonds are fashioned into a number of shapes, depending on the nature of the rough stone. The seven most popular shapes are princess, marquise, pear, emerald, oval, heart and round (also called brilliant). The round, brilliant cut is the most popular shape.

Diamond Color
Refers to the natural body color of a diamond. The finest and most expensive diamonds are colorless, but most diamonds show some trace of color. Color differences from one grade to the next are so subtle, only someone with a trained eye can distinguish them. Although most diamonds appear to the naked eye to be white, in fact they range from colorless to yellowish, with many gradations in between. When two different colored diamonds are compared side by side, the advantage of a stone with no underlying hue is obvious. It's important to remember that though increased shadings of yellow reduce the value of a diamond, they do not necessarily reduce its beauty. If a diamond is well cut, brilliance and dispersion will often disguise its coloration. Diamond color grades start at D and continue through the alphabet. Truly colorless stones, graded D, are extremely rare and are also very valuable.


Loose Diamonds appear Colorless. Most rare when factoring color.

Near Colorless


These Diamonds appear Colorless to all but the trained eye.

Faint Yellow


When mounted, gems of 1/2 Carat or more show traces of color.

Very Light Yellow


Increasingly yellow tint is viewable to even the untrained eye.

Light Yellow


Yellow tint is obvious. Known as "Champagne" colored.

Diamond Clarity
The rarest diamonds are flawless, absolutely clear throughout. Yet diamonds are a product of nature, and each gem has a unique pattern of lines or specks, called inclusions, that developed when the diamond was created. Some inclusions are so tiny even a trained expert can see them only under 10 power magnification. But all inclusions, even those that can't be seen by the naked eye and don't mar the stone's overall beauty, do reduce the value, and price, of a diamond. Most diamonds used in jewelry would be graded VS, SI or I on the scale below. Diamonds are graded under 10 power magnification.




No internal inclusions or surface blemishes show under 10-power magnification


Internally Flawless
No internal inclusions, but some minor surface blemishes show under 10-power magnification


Very Very Slightly Included
Tiny inclusions are extremely difficult to see even under 10-power magnification.

VVS1 and VVS2

Very Slightly Included
Minor inclusions may be difficult to see even under 10-power magnification.

VS1 and VS2

Slightly Included
Slight inclusions are seen under 10-power magnification.

SI1 and SI2

Inclusions are visible to the naked eye and range from those just visible (I1) to those seen very easily (I3)

I1, I2 and I3

Diamond Carat
A carat is the traditional unit of measure used to weigh diamonds. A carat is approximately 1/142nd of an ounce (200 milligrams). Larger diamonds are much more rare, and much more expensive when quality defined in terms of cut, color and clarity are equal. A one carat diamond is much more valuable than a grouping of several smaller diamonds which, when combined, add up to one carat in total weight. Even though large diamonds of great weight are impressive in size, they may not always be valuable because they are not judged by weight alone. A large stone holds little value if it lacks fire, brilliance, purity and high-grade color. One carat is also divided into 100 points. And diamonds may be described by the carat weight or by the number of points. For example, a 1 D4 carat diamond is also called a 25-point stone.

Precious Metal
Metal refers to what the jewelry is made of. Examples are 950 Platinum, 18K Yellow Gold, 18K White Gold, 14K Yellow Gold and 14K White Gold.
Stone Setting
Setting refers to a specific technique in securing a precious stone to a piece of jewelry.

Prong Setting- Prong settings are used to raise the stone up from the mounting allowing light to enter the various facets.

Common Prong Setting- A Common Prong Setting shares prongs which provides a nice clean look and allows the stones to be set closer together.

Channel Setting- A Channel is carved out of the metal and stones are placed inside the channel. A hole is placed under each stone allowing light to enter the facets increasing the fire and brilliance.

Bar Setting- Bar setting refers to the metal bars that separate gemstones along the individual precious metal. The bars provide tension locking the specific gemstone in place.

Pave Setting- Pave setting refers to multiple gemstones positioned extremely close together providing a brilliant surface.

Bezel Setting- Gemstones are secured with a rim made of precious metal (Gold or Platinum).
