Diamonds are the birthstone for the month of april, meaning that april born ladies or men have an extra reason to wear diamond jewelry.

The word diamond is derived from the Greek word “Adamas”, which means invincible or indestructible.

Diamonds are more or less invincible because they are nature’s hardest substance. Diamonds are 58 times harder than anything else in the world. The only thing that can scratch a diamond is another diamond. The hardness of diamond is 10 on Mohs scale.

Diamond professionals use the grading system developed by GIA in the 1950s, which established the use of four important factors to describe and classify diamonds: Clarity, Color, Cut, and Carat Weight.

The 4Cs describe the individual qualities of a diamond, and the value of an individual diamond is based on these qualities. The terms that people use to discuss the 4Cs have become part of an international language that jewelry professionals can use to describe and evaluate individual diamonds.

Today, the descriptions of each of the 4Cs are more precise than those applied to almost any other consumer product. And they have a long history. Three of them—Color, clarity, and carat weight—were the basis for the first diamond grading system established in India over 2,000 years ago.

These unique aspects define the cost of the diamond. Hence diamonds are considered most valuable precious mineral on earth.
