This diamond is the most expensive to ever be auctioned in London and it will surely be the main attraction point for the end on 2011. Actually this is the largest yellow colored pear-shaped diamond in the world. The color its self is a vivid yellow, the highest color grade a diamond can get, meaning that it’s very brightly colored without having parts of lesser coloration. According to Cora International, the company which is selling the diamond, it was discovered during 2010 in South Africa. The stone has been the main attraction at the London History Museum where it was temporarily displayed to the public earlier this year.

The question on everybody’s lips right now is who would buy a $11-15 million dollar diamond? Although the economic environment is rough right now, the company which owns the diamond have claimed that they got interest form all over the world from potential buyers. The fact is that it has never been owned by a private person so far and whoever will win the auction will get to be the proud first owner of the yellow diamond. And in case you’re wondering how come this diamond is yellow, you should know that it gets its color from traces of nitrogen found in the carbon makeup of the stone.

As a general practice, diamonds are graded according to four different criteria, including color. Typically, the less color is present, the more desirable the diamond is. Diamonds are also graded by their purity, the whitest or the clearest being the highest grade. The grading scale begins with D which is the purest white and ends with Z, which means that the stone has coloration or it’s tinted. Further than Z, a diamond’s color will be strong and it is rated as “fancy colored diamond.”

With yellow, however, the more coloration or tint, the higher and favored and sought after they are, therefore yellow with a color grade that beyond “Z” are the most luxurious and expensive diamonds. All yellow stones within this color grade range are labeled as fancy, while the N-Z range represents what is considered “light” coloration.

As stated above, yellow diamonds have their own color scale, the “fancy category”. In this category, there are varieties of hues which hold different names within the diamond industry such as fancy light yellow, fancy yellow, fancy dark yellow, fancy deep yellow and fancy vivid yellow or also known as canary yellow.

Fancy yellow diamonds with moderate or low color saturation may be considered as “fancy light yellow.” The “fancy dark yellow” is categorized depending on how dark the color is. For diamonds with high color saturation and a darker hue, the term “fancy deep yellow” is applied, and for lighter-colored diamonds with high saturation, “fancy intense yellow” is used. At last, “fancy vivid yellow” is the name applied to yellow diamonds with the highest level of color saturation.

So what makes a diamond to be yellow in color? For sure you are interested to know and here are some scientific facts for your reference. Diamond’s primary component is carbon, and nitrogen is the other most common element found in it. Nitrogen atoms have different number of electrons to carbon, which means that when they bond, a number of electrons remain unattached. These free electrons partly absorb blue and violet light wavelengths and the wavelengths that is not being absorbed give the diamond its yellow color.
