What is a Carat of Diamond?
One of the fastest ways you can tell a diamond’s weight is by putting the right values into a diamond carat calculator. However, to find the carat value of your stone, you need to first measure the weight using a diamond weight calculator. The diamond carat itself is a measurement of weight, where a single diamond carat is equal to 0.2g or 200mg.
The important thing you should remember about the carat is that it only refers to the diamond’s weight and nothing else. It is not a very accurate measure of the diamond’s size or density since bigger diamonds can still be of less carat than smaller ones.
Satang (Points) Vs. Carat
If you recently bought your diamond, you might have noticed that the individuals in the shop quoted the carat to you along with its satang value. The diamond’s satang value is another measurement of a diamond’s weight, equivalent to 1/100 of a carat. Therefore, 1 satang is equal to 2mg.
While you do not have to measure the satang units, seeing how the staff will measure them also allows you to find the accurate valuation of the stone.
How to Calculate Diamond Carat?
A diamond value calculator will need the accurate carat of a diamond to find its specific value. Luckily, there are multiple ways that you can calculate diamond carat weight, but only one of them is the most accurate. The other two methods you can use to calculate diamond weight are more or fewer estimations, but they can still be very effective when you do not have the right tools to measure the diamond weight.
Using a Diamond Weight Calculator
The first and most accurate way to calculate a diamond’s weight is by using a diamond weight calculator. You need a weighing scale to give you grams or milligrams. The scale is essential to finding the carat of the diamond since it will accurately measure its weight.
After you weigh the diamond on the scale, the next step that you need to take is to divide the value by 0.2. It is important to remember that the weight you need to divide should be in grams instead of milligrams.
So, for instance, the weight you got from the scale was 0.2g. Keeping the value in grams, you should divide it by 0.2, which gives you 1. The diamond that you just measured is equal to 1 carat.
Measuring Diamond Carat Sizes
Granted, an accurate gram scale can be hard to get by, so you might have to calculate the diamond carat using various measurements. Using diamond carat sizes for this diamond carat calculator, you can take certain measurements of your diamond, giving you a rough estimate of its weight.
You will need the diameter of the diamond, along with its depth, and then divide it by its total size. When you add all of these variables into the diamond carat size calculator, you will get the estimated carat of your diamond.
Estimate Weight by Diamond Carat Sizes
A diamond carat weight calculator has a specific formula that goes as follows:
Diamond carat = diameter x diameter x depth x 0.006
A diameter is essential to calculate diamond weight; you will put that into the diamond mm to carat weight calculator formula. Simply take a scale and measure across from the center for the diameter. Next, you want to measure the depth or height of the diamond, so you need to measure from the surface of the diamond to the tip of the carat calculator.
For instance, if you have a diamond with a diameter of 5mm and a total height of 2.5mm, you simply need to put them in the formula.
Diamond Carat = 5 (diameter) x 5 (diameter) x 2.5 (depth) x 0.006
Diamond carat = 0.375 carats
According to this formula, your diamond is likely close to 0.5 carats.
