What Carat Size Should I Choose for an Engagement Ring?

The carat size of a diamond symbolises much more than the size of the engagement ring. To make sure you pick the right one at diamond stores Vancouver, you should know how to choose the carat size of an engagement ring. In this blog, we'll discuss the carat size of engagement rings and the features which help in choosing the best carat size for your budget:

The short answer is that there is no single right carat size. Many couples in Canada choose a diamond close to 1 carat, but the best carat size for you depends on your budget, her hand size, the shape of the diamond and whether you choose a lab grown or natural diamond. A well cut diamond of a smaller carat size can look more beautiful than a bigger diamond with a poor cut!

What Does Carat Mean?

The carat refers to the weight of the diamond. It should not be confused with the size of the diamond. In the carat measurement system, 1 carat = 200 milligrams. Two diamonds of the same carat weight may look a little different in size because of their cut and shape.

Popular Carat Sizes of Engagement Rings

Here's the popular carat sizes of engagement rings explained:

  • 0.50 to 0.75 carat: A delicate engagement ring which suits small hands and a simple style.
  • 1 carat: The most popular carat size for an engagement ring as it is noticeable and easy to wear every day.
  • 1.50 to 2 carats: A bold engagement ring with more sparkle, often chosen with lab grown diamonds.
  • 2 carats and above: A statement engagement ring for someone who loves a glamorous look.

You should note that diamond prices go up at sizes like 1 carat and 2 carats. A 0.90 carat diamond can cost less than a 1.00 carat diamond and still look almost the same size on the hand!

Diamond Shape and Carat Size

The diamond shape refers to the outline of the diamond and it also determines how big the carat size of the engagement ring looks. Find out more about the diamond shape and carat size here:

Oval, pear and marquise shape diamonds look bigger than the round shape diamonds of the same carat size as the top of these diamonds is spread out more. The round shape diamond is regarded as the shape with the most sparkle, while the emerald cut diamond shows its carat size through a long and flat top. So if you want the carat size of your engagement ring to look bigger in the same budget, the oval or pear shape diamond can be chosen!

Carat Size of Engagement Ring as per Budget

Before you set out to purchase an engagement ring, it is important to learn how much of the budget should go to the carat size of the diamond. The cut of the diamond should be put first as a well cut diamond looks brighter and bigger than its carat size. A VS2 or SI1 clarity is enough for most engagement rings as these clarity grades look clean to the naked eye, and the money saved can go to a bigger carat size. If you want a bigger carat size of engagement ring in the same budget, then lab grown diamonds are a good option. You should also keep in mind her hand size as the same carat size looks bigger on a small hand!
