A classification of the diamond (Carat and Colors)

Earlier., I have introduced a classification Diamond with Clarity., Which is 1 of the 4Cs international gemological institute set up to the standard of grading diamonds and other precious stones. This will Separation using Carat and color of precious stones as well.

Carat

Weight, which is a standard to measure the weight of gemstones. This metric is compared with the standard carat weight is 0.2 grams. Homophone for the word carat (Karat) used to measure the purity of gold. The purity of gold is 99.99%, which is equivalent to 24 carats (Karat).

The origin of the word carat The seeds of the fruit of the seeds of this species karat, which will weigh on all seeds. Which in ancient times used widely. Because no clear standards to measure. Took seeds from Wangaratta. As the unit to measure the weight of gemstones.

Colors 

Shades of diamond classification Can be sorted from D to Z, which is represented by the letter D is meant to be white, which sometimes most people Thailand is called "water" would be even higher diamond white and yellow color additives. Diamond is colorless (Colors) are diamond, 100, 99, 98, or diamond, D, E, F, the diamond is nearly colorless (Near Colorless) include diamond, 97, 96, 95, 94, or G, H, I. , J color diamond sample. The other color Will move on to the bright light may be represented by the letter G yellow champagne. L to chase down a dark yellow to replace the P until the letter Z to a bright yellow. And was separated into shades of diamonds.

Diamond color classification To separate white and yellow only. I separated from this will be Fancy diamond pattern. Which is as colorful and quaint out.

Because the only yellow tones because. Carbon in the diamond When heat or chemicals other elements. Be made ​​diamonds are colored differently. The yellow diamonds are deficient in estrogen may contain elements with blue titanium and alloy steel. Or red may be a chromium alloy. The pink diamond is caused by the structure of the diamond itself. The green diamond is the radiation exposure. All these processes which cause the diamonds. Colorful different. And more expensive than white diamonds. Because rare However, White diamond crystal Still more popular than diamonds. There are currently several manufacturers. To improve quality white diamonds to create fancy color diamonds are formed by processes such as conducting a burn or radiation. Causing various colors like green, yellow and blue, and so on.
