What are the 4 "C"s diamonds? There are Color,Clarity,Cut and Carat .

Recognizing the evaluation criteria generally acknowledged by the market helps you choose the ideal diamond.

The weight unit of diamonds is Carat, 1 (carat: ct) and is also subdivided into 100 points. "Carob" is a kind of Arabian bean. It is very rich and sweet. Each Carob weighs an average of 1/5 g; therefore we use Carat as the weight unit of diamonds and gold. The higher the Carat is, the higher the price is. But the price and the Carat of diamonds is not added proportionally. The higher the Carat, the price will be doubled. Each weight has a relatively standard size. For example, the standard size of 1.00 carat is 6.40mm. If the standard size of 1.00 carat is above 0.1mm, the proportion could be too thin or too thick and affect the diamond brightness.

The color decides the diamond's simple radiance. The natural diamond colors are yellow, red, white, green, blue, purple, brown and black. Diamonds have different colors because of their different components. The main components of diamonds are carbon atoms. The atomic number of carbon atoms is 6, and the atomic number of nitrogen atoms is 7. Their atomic number is very close; therefore most diamonds have a bit of yellow in them because they have nitrogen atoms in them. Basically, when looking at diamonds, all D-J diamonds do not have colors. If you purchase diamonds just to wear them, you can have the option of lowering the color level in exchange for a higher Carat. But if the diamond has a strong and unique color, like red, blue, green or pink, the price will be very high. The most precious of the colored diamonds is the red diamond, then green and blue. Nowadays, yellow diamonds are very popular. It's shining yellow glow makes people think of wealth, sunshine and popularity. The white diamonds that Eric Company sells have all been inspected and are all higher levels than J color or fancy yellow colored diamonds, giving you a shining bright life.

Generally speaking, diamond clarity is the natural flaws of the diamond you see when looking through a 10X magnifying glass. According to the grading of the GIA, the diamond clarity has 11 levels. The best clarity is FL, IF, in which you cannot see any components through a 10X magnifying glass. It will not affect the brightness of the diamond, but if you use a 1000X microscope, all diamonds have components and not one of them is the same. The most common components are irregular spots, cloudy spots and feather shapes cracks. Components mainly affect light refraction and they easily block or trend optical lines. But if the diamond level is above level Sl1, the components are hard to see and do not constitute as visual defects. The diamonds that Eric Company sell are all above the SI 1level and are chosen by many appraisers. Even if they have components, they will not affect the brightness and color of the diamond.

Cut is the main key to turning an original rock into a diamond. It affects the visual size, beauty and light refraction. Light, fire and flashes are the three reasons that make a diamond shine. Out of all the Gemstones, diamonds are the brightest ones. But you need an appropriate angle and the biggest light refraction to see the original beauty and brightness of the diamond. GIA's Minkowski calculated a perfect cut ratio, which was named the American ideal Cut. But he also lost the most weight of the diamond. Most diamond markets favor Excellent, Very Good and Good. Furthermore, there are many non-standard cuts, for example, star-shaped, heart-shaped, oval-shaped, round rose-shaped and square leidien types. Cuts elevate the art and variety of diamonds. Therefore, it is said that cuts give life to diamonds. Diamonds with better cuts can have the best light refraction angle and the most astonishing brightness. On the contrary, if the cut is not done well, the section will be irregular and asymmetric, which results in a broken and messy optical line, making the diamond unattractive. The diamonds that Eric Company provide are ordered and cut by the original stone buyers. Our diamonds have a perfect brightness and customers shine. Very Good Good Fair Poor
