Diamond Carat Weight

The term “Carat” originated mainly from the idea of carob seeds. This seed was used in the past as a means to measure gemstones and jewelry weights. As it was believed that they had little to no mass distributions to them. But it was not the right, as later it was found that the carob seeds are the same as any other seeds present there. And their mass distribution also differs from each seed to other like those other species.

The newly formulated term “Carat” simply is a derived constant quantity to measure the weight of the diamonds. Before during the 1570s, each country used to have its specific carat formulation. Later on in the year of 1907, at the Fourth General Conference of Weights. It was declared as an agreement that a carat should be equivalent to 200 milligrams, precisely. Thus the system changed and carat or more specifically modern carat had a universal measurement which was and is followed all over the world.

The carat weight of a diamond has a huge impact on the price of the stones. Simply speaking, larger carat is equal to a more expensive stone. It is because diamonds that are larger in carat quantities tend to be bigger. And hence are more desirable and rare in making. However on must not also neglect the cut, color, and clarity aspects of the stone. Two different stones of the same carat weight can hugely differ in their costs and values if these other aspects of grading are taken into consideration.

The Idea of Carat Size Charts

We, humans, are clever species. We tend to simplify everything according to our self convenience. From time to time and in the present too, whenever there come complicated relations and conversion criteria. We classify and chart up the information to ease things up.

In the case of diamonds to there are specific size charts about each shape and cut respectively. Here we will be noting down the millimeter to carat weight size conversion chart of ideal diamond cuts. Please have a look to have an easier understanding.

Diamond Size Chart (conversion from mm to carat weight)

4.0 mm diameter = 0.25 ct.

5.1 mm diameter = 0.5 ct.

5.8 mm diameter = 0.75 ct.

6.4 mm diameter = 1.0 ct.

6.9 mm diameter = 1.25 ct.

7.3 mm diameter = 1.5 ct.

7.7 mm diameter = 1.75 ct.

8.1 mm diameter = 2.0 ct.

8.5 mm diameter = 2.25 ct.

8.9 mm diameter = 2.5 ct.

9.0 mm diameter = 2.75 ct.

9.3 mm diameter = 3.0 ct.

9.5 mm diameter = 3.25 ct.

9.75 mm diameter = 3.5 ct.

9.9 mm diameter = 3.75 ct.

10.1 mm diameter = 4.0 ct.

From the above mentioned chart, we can see that the width of a 1 carat Ideal Cut diamond is about 6.4 to 6.5 mm in diameter.
