Diamond Education:

Carat:

Caratage is the easiest of the 4 Cs to understand and measure, inasmuch as it refers to weight. Furthermore, because the density of diamonds is essentially constant, as the caratage of a diamond increases, so does its relative size. It is simple to obtain, because all that is required to weigh the diamond on a scale. Unlike the other three Cs – color, clarity and cut – it is not subject to human interpretation.

The term “carat” originates from the Greek word “karaton,” which was the carob seed that was used to balance scales in ancient times. A carat is equal to 200 milligrams.

It is important to distinguish between “carat,” which refers to the weight of a gemstone, and “karat,” which refers to a fineness of a precious metal.

Carats usually are expressed a full number or zero to two decimal points, such as 2.15 carats 0.60 carats. Hundredths of a carat are sometimes referred to as points, meaning that 100 points equals 1.00 carats.

Another term that is sometimes used is “grainer.” It dates back to the trade in the Far East, where diamonds were weighed against grains of rice, with 1.00-carat equaling four grains of rice.  Members of the trade will today refer to four grainers (1.00 carat), six grainers (1.50 carats) and eight grainers (2.00 carats). A one grainer could alternatively be referred to as 25 pointer or a 0.25-carat diamond.

The price of a diamond does not necessarily rise at rate that is consistent with the rise in number of carats. Larger diamonds are rarer, so they typically have a greater monetary value per carat. In other words, the value rises at a faster rate as it gets bigger in size. And there are other factors at play. For example, a 0.95-carat stone is 5 percent smaller than 1.00-carat stone, but it is more than 5 percent lower in value. Passing the 1.00-carat benchmark tends to boost a stone’s value, because of market demand. This does not exist between a 1.01-carat diamond and 1.02-carat diamonds, but it does between a 0.99-carat diamond and  a 1.00-carat diamonds.

Clarity:

Clarity refers to the purity of the diamonds, or to the degree to which it is free of blemishes and imperfections. In principal, as the clarity of the diamond increases, its value is enhanced.

The clarity of a polished diamond is affected by both external blemishes and internal imperfections or inclusions, some of which were created in nature when the diamond was formed and others during the cutting and polishing process. Internal inclusions include piqués, or dark spots, gas bubbles or lines, and even tiny crystals. Sometimes cracks in the diamond crystal, or fractures or feathers affect clarity, passing through the interior and sometimes reaching the surface.

Clarity characteristics are what make each diamond unique, since there are no two stones that will have the same exact inclusions in the same locations. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how they affect the overall appearance of the stone.

FL, IF (flawless, internally flawless): A grade given to a polished diamond where no external blemishes or internal inclusions are visible using a standard 10X-magnification loupe. Experienced jewelers seldom see such stones, and some even argue that flawless diamonds simply do not exist.

VVS1, VVS2 (very very slightly included): With VVS1 being the better of the two, such grades are assigned to diamonds in which imperfections and inclusions are very difficult to spot, even under the magnification of a 10X loupe.

VS1 and VS2 (very slightly included): With VS1 being the better of the two, such diamonds appear clean when seen with the naked eye, but the inclusions are relatively easily spotted with a 10X loupe.

SI1, SI2 (slightly included): With SI1 being the better of the two, these diamond’s inclusions can be detected with difficulty with the naked eye, but are quite obvious under the magnification of a 10X loupe. SI3, which is used by certain labs, although not GIA, is a grade slightly lower than SI2.

I1, I2 and I3 (included): With I1 the best of the three, these grades are assigned to diamonds where the inclusions can be seen easily with the naked eye.
