You’ve narrowed down your choice to two gorgeous band designs. Both feature a sparkling lab-grown diamond as their focal point. But which one will best suit you? This article will explain everything you need to know about carat weight.

What is a diamond carat?


A carat is equivalent to 200 milligrams or 0.2 grams. It is a measurement unit that expresses the weight of lab-grown diamonds and other gemstones.


The word carat is derived from the Indian term “karat,” which is a unit of gold that is used as a measure of its purity. The “carat scale” is a system that is used to determine the number of lab-grown diamonds that you should purchase based on the quality and their weight.

How does carat affect the price?


The price of a lab-grown diamond is determined by the cut, clarity, color, and carat, known as the four Cs. The carat size is the most important factor - when the lab-grown diamond carat weight increases, the price also increases.


What does "TW" mean?


The “TW” of a lab-grown diamond is the short form of the total weight of a piece of jewelry, not only limited to diamond carat weight.

What is the price of one-carat lab-grown diamond?

A one-carat engagement ring is a popular option. Keep in mind that it is not only the weight of lab-grown diamonds that determines its price. The cut, clarity, color, and carat are also essential factors. Two lab-grown diamonds of equal carat weight can have different prices.

How many carats should my ring have?

There is no classic rule that people should follow. However, the higher carat weight may not be better than the smaller one as cut, clarity, and color also matter. If you are buying a lab-grown diamond ring, you should also consider your total budget, stone shapes, and ring designs.
