What Carat Diamond Should I Choose?

So, you're in the market for a diamond ring. But with all of the options out there, how do you know which carat size is right for you? This blog post will explore the available carat sizes and help you decide which is right for you. We will also touch on the different shapes and cuts of diamonds to help you narrow down your search. 

The Carat Scale

When choosing a diamond, size is not the only factor to consider – but it is an important one. The carat weight scale goes from 0.2ct up to 10cts, and each carat is divided into 100 'points'. So, a half-carat diamond would be 50 points.

The term 'carat' is derived from the Ancient Greek word for the carob seed – which was used as a unit of measurement in early times. The modern-day use of the term first began in the 19th century when diamonds were being mined in South Africa.

There are two things to keep in mind when considering carat weight:

1) A higher carat weight does not necessarily mean a better quality diamond, while the other C's (cut, clarity and colour) are just as significant, if not more so.

2) Carat weight has a direct impact on price. All else being equal, a 1ct diamond will cost more than a 0.5ct diamond because larger diamonds are much rarer than smaller ones. In conclusion, when choosing a diamond, it's important to consider both the carat weight and the other C's (cut, clarity and colour). This will ensure you get the best quality diamond for your budget.

What does carat mean in diamonds?

When it comes to diamonds, carat weight is the measurement of how much a diamond weighs. It's the size metric that most people are familiar with and is often used to determine a diamond's value.

One carat is equal to 200 milligrams, or 0.2 grams. So, if you see a 1-carat diamond priced at $2,000 per carat, the stone itself would cost $4,000.

The term "carat" is derived from the Greek word for a carob seed, which was historically used as a unit of measurement for gemstones. Nowadays, diamonds are measured in metric carats (ct), with one ct being equal to 0.2 grams.

While carat weight is important when choosing a diamond, it's not the only factor to keep in mind. The quality of a diamond also depends on its cut, colour, clarity and certificate.

How the Carat Affects a Diamond's Price

When it comes to diamonds, size does matter. The carat weight of a diamond is the measure of how much the diamond weighs. The higher the carat, the more expensive the diamond.

Why is this? It all comes down to supply and demand. Diamonds are rare, and so the larger the diamond, the rarer it is. And because they're so rare, they're also more valuable. So if you have your heart set on a bigger diamond, be prepared to pay a little bit more.

Of course, other factors affect a diamond's price besides its carat weight. The quality of the cut, clarity and colour all play a role in determining the price. But if you're looking at two diamonds of equal quality, the one with the higher carat weight will always be more expensive.

What to Consider When Choosing a Carat Size

When choosing a carat size for your diamond, there are a few things to consider. First, think about what size stone you want. Do you want a large, show-stopping diamond or a more modest stone? The carat size will also affect the price of the diamond, so be sure to set a budget before shopping. Keep in mind that the cut of the diamond can also affect its appearance, so choose a carat size that will best show off your gem's quality.

What Carat Diamond Should I Get for an Engagement Ring?

When shopping for an engagement ring, you may have noticed that diamonds are described using the "carat" unit of measurement. But what does carat weight actually mean, and how does it affect a diamond's appearance? Here's everything you need to know about diamond carat weight so you can choose the best stone for your engagement ring.

The first thing to understand is that "carat" is a measurement unit used to describe a diamond's weight, not its size. So when a jeweller says a diamond is "one carat," that doesn't mean the diamond is precisely one inch in diameter (although some very rough estimates of a diamond's size can be made based on its carat weight).

Instead, think of carat weight as meaning "how much this diamond weighs compared to other diamonds." For example, most diamonds used in engagement rings or wedding rings fall between 0.25 and 2.0 carats.

Now that you know what carat weight means, you might wonder how it affects a diamond's appearance. The answer is quite a lot! Here are three important things to keep in mind when choosing a diamond-carat weight for your engagement ring:

  1. Larger diamonds are rarer than smaller diamonds. They're also more expensive, so if you're working with a limited budget, you'll want to stay on the lower end of the carat weight spectrum.
  2. Diamonds over one carat in size usually look bigger on the finger than smaller diamonds, even if they're actually the same size. This is because larger diamonds tend to have larger facets, which reflect more light and give them a larger appearance.
  3. When shopping for a diamond over one carat, look for stones with good symmetry and proportion. Many large diamonds can appear dull or misshapen due to poor cutting, so choosing a stone that has been cut well is important.

Ultimately, the best carat weight for your engagement ring depends on your budget and personal preferences. If you're looking for something unique, but money is tight, consider sticking to stones between 0.25 and 0.50 carats — these sizes offer plenty of sparkle without breaking the bank! But, on the other hand, if you're willing to invest in something special, then go ahead and choose a diamond over one carat — make sure it's been cut well so it looks its best.

How does the Diamond shape affect the carat size?

Regarding carat size, the shape of your diamond can significantly impact it. For example, round diamonds are typically the most popular choice for engagement rings because they tend to have the largest carat weight. However, if you're looking for a unique shape, like an oval or marquise, you may sacrifice some carat weight.

The good news is that no matter what shape you choose, your diamond will still be beautiful and sparkly. So ultimately, it comes down to personal preference. So if you're looking for a large diamond that makes a statement, go with a round. But if you want something different that will stand out from the rest, pick another shape!


Assessing the value of any given diamond requires considering all four Cs: cut, clarity, colour, and carat weight. Each element contributes significantly towards determining what makes one stone better or worse than another—so make sure you research before investing any money! With careful consideration and knowledge about these factors, you can ensure that you get exactly what you're looking for without spending more than necessary on your purchase!
