A diamond’s weight is represented in carats. Carat is a measurement of weight, NOT size. Weight impacts the price most dramatically out of the various diamond characteristics. When diamonds are mined, large gems are discovered much less frequently than small ones, which makes large diamonds much more valuable. In fact, diamond prices rise exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality.

Most people think that the bigger the carat the bigger the diamond, the happier the lady will be but there is more to consider than just that. You’ll have to consider her style, the size of her finger, the size of your setting, and your budget.

The popular carat sizes are 0.50ct, 0.75ct, 1.00ct, 1.50ct and 2.00ct. There are often bargains to be found at just under these most popular sizes and many of these bargains can have superior cuts which equate to more diamond sparkle and life.

The cut of a diamond determines its brilliance. There is no single measurement of a diamond that defines its cut, but rather a collection of measurements and observations that determine the relationship between a diamond’s light performance, dimensions and finish. While there are many factors to bear in mind when choosing a diamond, diamond cut is probably the most important to consider, as it has a direct correlation to a diamond’s appearance. A diamond with Ideal/Excellent cut grade proportions will return the maximum amount of light to the viewer’s eye, the diamond will appear more brilliant and beautiful as a result.

People often mix up the difference between the ‘Cut’ of a diamond and the ‘Shape’ of a diamond. Diamond shape, by contrast, refers to the shape into which the diamond is cut. When diamond cutters receive rough, uncut diamonds, they typically assess the natural shape of the diamond and determine which shape to cut the diamond into. The most common diamond shape is a round brilliant diamond. Princess, Emerald, and Asscher cut diamonds are other popular shapes.
