Diamond Carat has a huge significance, not only on how beautiful the stone looks but also on the price and value of the diamond. It generally is the measurement of the weight of the stone, be it a naturally grown diamond or a lab-grown one. Many false ideas are revolving around this particular C (the diamonds overall quality is claimed to depend on its 4 C’s-cut, clarity, color, and carat). 

It does not simply mean that a diamond has a bigger carat size if it tends to look bigger than another diamond and this applies to the alternative as well. The look of a diamond is a deceiving factor which, generally depends on its cut factor.

Another, important factor for people to consider is, that bigger carat simply does not equate to better-looking diamonds. A lab-grown diamond of smaller carat size can look more beautiful and appealing. Than a diamond which is bigger in carat size than the former.

Whatever the reasons to choose the size of the carat may be. The ultimate reason should be the price or cost-effectiveness of the particular carat size. We generally know for a fact, that lab-grown diamonds are about 30 percent lesser in their prices. Than the naturally grown diamonds.

Shape of the Diamond


One of the most obvious but noteworthy reasons, is the shape of the diamond. One shall notice and find that the round cut diamonds are the ones. That are the most costly, be it natural or lab-grown type of diamond. It is simply because this particular cut offers the best possible sparkle, scintillation, and fire than any other cut tends to provide. Taking the other cuts according to their degree of brilliance, comes the oval cuts, emerald cuts, radiant cuts and so on.

Diamond Clarity

This terminology falls amongst the 4 important C’s of the diamond. It refers to the cleanness of the diamond, i.e. the number of inclusions, blemishes, and flaws that diamonds contain. The ones that contain a lesser number of inclusions are graded higher. And are usually more expensive than the ones that contain a higher number of inclusions; which are graded lower and are hence cheaper accordingly. The best suggestion that can be given regarding clarity of a diamond is to look for VS1 and VS2 graded diamonds. As they will be eye-clean variants yet much lesser in terms of their costs than the VVS and FL variants.

Diamond Cut


Another C from the important 4 C’s, the cut quality of a diamond simply refers to its degree of beauty and visual appeal. The higher the cut grading, the expensive the diamond, the lower the grading the cheaper. The best cuts are generally termed as “Ideal” and “Excellent” ratings and the lower or so to speak the affordable ones are graded as “Very Good” and “Good”.

Diamond Color


Representing another of the C from the 4C’s of a diamond, the color of a diamond refers to what color the lab-grown diamond is. The scale usually starts with the letter “D” which usually means colorless diamonds, which is the highest rating of diamond color grade. It ends with “Z” representing the diamonds that contain brownish or yellowish tints and is the lowest color grade rating.

Similar to the other C’s the higher the grade, the higher is the price and vice versa. It is usually recommended to go for the diamonds which fall in between the G-J color ranges, as these are the diamonds that look colorless to the naked eye but cost significantly lesser than the high grades that there are.
