A guide to finding the carat that suits you best

What does carat mean?

Carat is a unit of measurement that indicates the weight of a stone. One carat equals 200 milligrams. It is important to note that carat weight does not necessarily reflect visual size, because different cuts can make a stone appear larger or smaller. Understanding carat is therefore crucial when selecting a stone.

Carat weight is only one of the four Cs that determine quality, with the other three being cut, clarity and colour. Each of these factors can significantly influence visual appeal and value.

What is the best carat?

The best carat depends on your preferences and your budget. For many buyers, a one-carat stone strikes a good balance between size and affordability, but the ideal choice varies. When thinking about which carat weight is right, consider cut, clarity and colour as well, because these also shape appearance and value.

Trends and cultural preferences matter too. In some regions larger stones are highly prized, while in others the focus is on quality and craftsmanship regardless of size.

How to select the best carat

Selecting the right carat means balancing size, quality and budget.

• Determine your budget. Establish how much you are willing to spend, since carat weight has a big effect on price.
• Understand carat weight. Remember that carat refers to weight, not size. Different cuts can make stones of the same carat look larger or smaller.
• Balance the four Cs. Consider carat alongside cut, colour and clarity. A well-cut stone can appear larger and more brilliant than a poorly cut, heavier one.
• Consider the setting. The setting can enhance or reduce apparent size. A halo setting, for example, can make a smaller carat stone look larger.
• Personal preference. Choose a carat weight that matches your style and the intended occasion, whether for daily wear or special events.

It also helps to view stones in person or through high-quality images to understand how different carat weights and cuts appear in various settings.

Are lab grown diamonds measured in carats?

Yes. Lab grown diamonds are measured in carats just like mined stones. This standard measurement allows a direct comparison, so you can make an informed decision based on carat weight regardless of origin.

Lab grown diamonds also go through the same grading processes as mined stones, which provides transparency and reliability in both carat weight and overall quality assessment.

Lab grown versus mined: comparing carats

When comparing the two, carat measures weight in both cases, which gives a standardised comparison. A carat represents 200 milligrams either way. While the carat weight is the same, lab grown diamonds often offer better value, because they can provide larger carat sizes at a more affordable price.

Lab grown diamonds are also created in controlled environments, making them a sustainable choice without compromising on the quality or appearance of the stone. They have a shorter supply chain and lower environmental impact, which adds to their growing popularity among eco-conscious buyers. They also allow precise cutting techniques, which supports exceptional quality and brilliance.
