Before the purchase of diamonds, then you should consider and pay attention to many things to spend money, not lost in vain. We can examine the experts' discussions, such as the GIA (Gemological Institute of America). Here's what you should consider before buying a diamond.
Carat
Diamonds and other gemstones are weighed in carats meters: one carat equals 0.2 grams, about the same weight Paperclip. (Do not confuse carat with CARAT, as in "18-carat gold", which refers to the purity of gold.)
As the dollar is divided into 100 cents, carat is divided into 100 points. For example, a diamond weighing 50 carats point 0:50. But two diamonds of equal weight boxes have very different values depending on the other members of the Four C: clarity, color and cut. Most diamonds used in jewelry CARAT weight or less.
Because even a fraction of boxes CARAT significant differences in cost, accuracy is very important. In the diamond industry, weight is often measured in one hundred thousandth CARAT, a hundredth of a carat. weight of a diamond over one carat are expressed in carats and decimals. (For example, CT 1:08. Stone is described as a "single point of eight carat Oh" or "one of the eight.")
Getting Started CARAT?
CARAT, a standard unit of weight for diamonds and other precious stones, derives its name from the carob seed. Because these small grains have a fairly homogeneous mass of EME operators have used early as a counterweight to balance the scales. Modern metric carat, equal to 0.2 grams, was adopted by the United States in 1913 and shortly thereafter in other countries. Today carat weighs exactly the same in all corners of the world.
Color
Diamond color is what you do not see. Diamonds are graded by how much they are willing to address gray - less color, the more valuable. (An exception is a fancy color diamond, pink and blue, Standard and Poor ", which goes beyond the range of colors.)
Most diamonds found in jewelry stores run from colorless to almost colorless, with hints of yellow or brown.
color scale for diamonds GIA is an industry standard. The scale begins with the letter D, or colorless and continues with an increase in the presence of the color of the letter Z, or almost colorless. Each class letter clearly defined set of color appearance. Diamonds are graded by color, by comparing them with stones of known color under controlled lighting and precise viewing.
Many of these colors subtle distinctions so they are invisible to the untrained eye. These small differences, but rather a very big difference in quality and price of diamonds.
Clarity
Because diamonds are formed deep in the earth under extreme heat and pressure, they often contain unique birthmarks, or internal (inclusions) and external (blemishes).
Purity refers to the absence of these inclusions and blemishes. Without these signs of diamonds are rare, rare and affects the value of a diamond. Using the GIA International Diamond Grading System ™, diamonds are given a degree of clarity that ranges from Flawless (FL) to diamonds with visible inclusions (I3).
Each diamond is unique. None is absolutely perfect in 10 × magnification, although some come close. Known for flawless diamonds are extremely rare. Most jewelers have never seen.
GIA Clarity Scale includes 11 species, most diamonds VS (very slightly included) or SI (slightly included) category. To determine the degree of transparency in the GIA considers the size, type, location, color or relief, and the amount of clarity characteristics visible under magnification × 10.
Flawless (FL) - No inclusions or visible damage to the grader qualified at a magnification of 10 ×
Internally Flawless (IF) - No inclusions and discoloration is only visible to the qualified grader at a magnification of 10 ×
Very, very slightly included (VVS1 and VVS2) - Inclusions are difficult for a skilled grader to see the larger 10 ×
Very slightly included (SP1 and SP2) - inclusions are clearly visible at 10 × magnification, but may be considered a minor
Slightly Included (SI1 and SI2) - inclusions visible to the qualified grader at a magnification of 10 ×
Included (I1, I2 and I3) - inclusions visible under 10 × magnification and may affect transparency and brilliance.
Cut
Fuel cut, which is a factor of fire diamonds, sparks and glare.
58 aspects of the traditional round brilliant cut diamond, each carefully cut and defined, are as small as two millimeters in diameter. But without this precision, a diamond, you can no longer be so beautiful. Charm Diamond particular depends more cutting than anything else.
Although very difficult to analyze or quantify the full size of the diamond has three attributes: Brilliance (amount of light reflected by the diamond), fire (dispersion of light on the colors of the spectrum) and scintillation (flashes of light and glare, and the diamond is moved PLS).
Top of the understanding of diamond shaped like a diamond. The shape of the bright standard tower is normally used in most diamond jewelry. All other forms are known as fantasy. Traditional forms of fantasy include marquise, pear, oval, emerald cuts. Hearts, cushions, triangles and many others also gaining popularity in the diamond jewelry.
As a value factor, but refer to the proportion cut diamond polish and symmetry. For example, look at the side view of a standard cycle brilliant. The main components, from top to bottom, are crowns, belts and flags. round brilliant cut diamond has 57 facets, or 58, 1958 for an apartment, the guy at the bottom of the flag is known as the culet. The large flat facet on top of the table. Proportions of a diamond refers to the relationship between the size of a table, crown angle and depth of the flag. A wide range of combinations are possible, and these ultimately affect the interaction of light with a stone.
