Measuring Luxury: A Guide to Diamond Carat and Size

The bigger the diamond carat the better. Well…sometimes

Carat weight is one of the most important aspects to consider when purchasing a diamond. The metric system is used to compute the weight of a diamond, which influences its price.

We will discuss what a diamond’s carat is, how it is calculated, and the elements that influence its price.

What is a diamond carat?

A carat is a unit of measurement used to calculate a diamond’s weight. 200 milligrams, or 0.2 grams, make up one carat.

Additionally, 100 points can be used to represent a carat, with each point equaling 0.1 carats. Consequently, a diamond that weighs 0.50 carats can also be referred to as a 50-point diamond.

The ratio between diamond size and carat weight might change based on other elements like cut and shape.

For instance, a well-cut diamond may seem bigger than a diamond with a worse cut that is greater in carat weight. However, generally speaking, a bigger diamond will come from a higher carat weight.

Diamonds of high quality can be found in all size ranges.

Having said that, the bigger a high quality diamond is, the rarer it is.

This is a phenomenon that is found not only in diamonds but in gemstones as well.

Generally, the bigger the diamond, the more expensive it is.

Once a diamond breaks the 1 carat mark, the price difference is quite high as long as the color and clarity are good.

The best way to weigh the diamond carat

A precision scale made specifically for weighing gems and jewelry may be used to determine the weight of a diamond.

The scale is calibrated to determine a diamond’s carat weight in metric units. It’s crucial to understand that karats, a unit of measurement for gold, and carats are two different things.

The gem is put on the scale and weighed in order to determine a diamond’s carat weight. After that, the weight is measured in points and carats. Typically, the carat weight is rounded to the next hundredth, as in 1.50 or 2.75 carats.

Since diamonds are measured by, carat weight, and not size, two diamonds of the same weight could have different sizes.

Why? If a diamond is cut too shallow (or flat) it will have a larger diameter, but shallow depth and appear larger.

Likewise, if a diamond is cut too deep (or pointed) it will have a smaller diameter and deep depth and appear smaller….This is why cut is so important.

You want to make sure the diamond is cut to proper proportions.

Not only does it make a large difference in the diamond’s ability to reflect light, but a poorly cut diamond will not be proportionate in size to a diamond cut to proper specifications.

This will mean that you will have light leaking out of the sides of the diamond and thus getting poor internal reflection .

Sacrificing the cut to get a heavier diamond weight defeats the purpose as all you’ll end up with is a large dead diamond….instead of a fiery stone.

Size matters but not at the expense of cut, clarity and color.

Typical Myths About Diamond Carat

  • Bigger is always better. Reality: While a larger carat diamond can be impressive, other factors like cut, color, and clarity also significantly affect a diamond’s overall appearance and value.
  • Carat and size are the same things. Reality: Carat is a unit of weight, not size. Two diamonds with the same carat weight may appear different in size if one is cut with better proportions.
  • Higher carat diamonds are always more valuable. Reality: Diamond value is influenced by carat weight but also by factors like color, clarity, and cut. A smaller diamond with exceptional quality can be more valuable than a larger diamond with lower quality.
  • All diamonds of the same carat weight look the same. Reality: Diamonds with the same carat weight can look different due to variations in cut and proportions. The way a diamond is cut and shaped affects how it reflects light.
  • A diamond must be a certain carat weight to be considered an engagement ring. Reality: The choice of a diamond’s carat weight for an engagement ring is a matter of personal preference and budget. There’s no set rule for the “right” carat weight.
  • Diamonds below one carat are not valuable. Reality: Smaller diamonds can be highly valuable, especially if they exhibit excellent color, clarity, and cut. They are often used in accent stones in jewelry.
  • Carat weight doesn’t impact a diamond’s brilliance. Reality: Carat weight can influence how light interacts with a diamond. Larger diamonds may display more fire and scintillation, but only if they are cut well.

It’s important to consider all the “Four Cs” (carat weight, cut, color, and clarity) when choosing a diamond, as they all play a role in its overall quality and appearance.
