The most important aspect while buying diamonds is to be aware, of the differences between colored diamonds that are formed naturally and ones that are man-made. Diamonds were traditionally thought of as white or clear. As a matter of fact diamonds do have color and this can be graded. There are different types of colors that are available from black loose diamonds to pink and then there are yellow diamonds, which look stunning.
Loose diamonds that are colored naturally are extremely rare and hence are tagged at an incredibly high price. There are basically three ways in which colored diamonds are formed by nature. The first method is when a foreign constituent is introduced in the carbon material that a diamond is made from. More often nitrogen can cause a diamond to have yellow or orange hues, while boron can make it blue in color. The next method is when pressure compresses the carbon and creates a red, pink, or purple hue. Out of all the loose colored diamonds, Green, red and purple diamonds are considered very uncommon and fetches high price. Research has indicated that there is only six naturally formed red diamonds currently in the market. Natural fancy colored diamonds are so rare that there are approximately 10,000 colorless stones for each colored stone.
Fancy colored loose diamonds can also be man-made. There are many ways that can be used to color diamonds. On the other hand, these stones can be formed in a matter of weeks, where as it takes thousands of years for natural colored diamonds to be formed. These types of synthetic diamonds are a lot like the real diamonds, and only high tech equipment might be able to detect slight differences, in the crystal formations. Most of the times these equipments are used when people come to sell their used diamonds to know whether they are fake or real.
