Diamond Carat Weight

Carat in the context of diamonds denotes its weight rather than size or quality. 
A metric unit known as a "carat" is precisely defined as 200 milligrams and is further divided into 100 'points,' allowing for highly accurate measurements to the hundredth decimal place. For diamonds weighing less than one carat, a jeweller may solely use 'points' to describe the weight, such as calling a 0.25-carat diamond a 'twenty-five pointer.' Conversely, diamonds weighing more than one carat are expressed in carats and decimals, like a 1.08-carat stone being referred to as 'one point oh eight carats.'
In the realm of diamonds, the price tends to rise with increasing carat weight due to the rarity and heightened desirability of larger stones. However, it's crucial to recognise that two diamonds with identical carat weights can vary significantly in value and price based on three other critical factors within the diamond 4Cs: Color, Clarity, and Cut.
While understanding the definition of carat is valuable, it's equally important to emphasise that a diamond's overall worth is determined by considering all aspects of the 4Cs, not solely relying on carat weight.
