As the name might suggest, this refers to the weight of diamond. Carat weights are determined out of a possible 100 points. For example, a one-carat diamond is comprised of 100 points, ½ a carat of 50 points and so on.
Carat weight alone often does not precisely articulate its size; It is recommended that observing carat weight alongside two other characteristics – the distance across the top of the diamond measured in millimeters and its cut grade – to achieve a better understanding of diamond sizing.
To begin with, the distance across the top of the diamond is an important facet of the process; viewing it from this angle may make it appear larger than it actually is, and it also serves as the vantage point from which we see a stone when setting it into a ring.
Furthermore, a diamond’s cut grade is a significant gauge of carat weight; a diamond cut with adequate proportions will project the most amount of light (sparkle) out of its top. As such, when a diamond has an ideal cut, the light reflected on top gives it a larger appearance. Conversely, the majority of a poorly cut diamond’s weight may be hidden in its base, giving it a smaller appearance than what its carat weight might indicate.
Considering this, it is possible to have a diamond of a lower carat weight but a higher cut grade that appears larger than a diamond with a larger carat weight but is of a poor cut grade.
After selecting your cut, color, and clarity grade, it will be easy to find the carat weight of a diamond falling in your price range.
