Diamond is a well-known April birthstone. The gemstone got its name from the Greek word adámas which means unbreakable," "proper," or "unalterable. The Greeks used to believe that diamonds were pieces of stars fallen to earth and that they encouraged purity, love and joy in wearer. Traditionally, an epitome of strength, invincibility and fearlessness, diamond is also a symbol of indestructible love. The gemstone is categorized according to Four C’s which refer to its color, cut, clarity and carat weight.
1) Color- Diamonds are graded on the GIA color scale from D (highest grade) to Z (lowest grade).
2) Cut- The cut of a diamond describes the quality of workmanship and the angles to which a diamond is cut.
3) Clarity- Clarity is a measure of internal defects of a diamond called inclusions.
4) Carat Weight - The carat weight measures the mass of a diamond.
The hardness of diamond is the main contributor to its suitability as a gemstone. On Mohs scale of mineral hardness, where hardness is defined as resistance to scratching and is graded between 1 (softest) and 10 (hardest), diamond has a hardness of 10 (hardest) on this scale. As a diamond can be only scratched by other diamonds, it maintains polish extremely well. Unlike other gemstones, diamond is a perfect for daily wear jewellery and its resistance to scratching is a significant factor of its popularity as the most preferred gemstone in wedding and engagement jewellery, which are often worn every day.
