0.30 Carat Diamond Ring

The weight of any size diamond is measured in what is called a carat. This small unit equates to 200 mg. A diamond’s carat weight is often expressed in fractions or points. One carat = 100 points. For instance, about 0.30–0.36 ct. is often referred to as 33 points, 30 carats or ⅓ of a carat. The size of a 0.30 carat diamond ring equals approximately 4–4.45 mm.

In terms of shape, a 0.30 ct. round diamond ring will seem bigger than many other cuts. The circular shape is shallower so much of the carat weight is reflected in the diamond size appearance. More elongated cuts such as the marquis, emerald, and oval shapes also tend to appear larger than their actual carat weight.

What is a Diamond’s Carat Total Weight (CTW)?

A diamond’s CTW is the combined weight of all the stones in a single ring or another piece of jewelry. For example, a pair of half carat diamond earrings would have a total weight of 0.50 ct., with each piece weighing 0.25 ct.

The FTC adheres to strict guidelines regarding carat weight and the range that fraction represents. The 0.30 diamond ring you choose may weigh a slight fraction higher or less than the stated carat weight.

Why is Carat Weight so Important?

A diamond’s carat weight is one of the biggest price influencers, in addition, to cut, color and clarity. A 0.30 diamond engagement ring is a smaller size, larger stones are rarer and higher in value. The investment increases with the weight of the diamond.

Does Carat Weight Affect Diamond Size?

The higher the carat size, the more the depth and diameter increase. A single carat diamond ring with a diameter of about 6.5 mm, will not appear to be twice as wide as a 0.50 ct. stone that with an approximate 5 mm diameter. Also, consider that a 0.30 ct. the diamond engagement ring will look much grander on a small, dainty hand than on one with long fingers.
