Understanding Diamond Carat Weight
đŸ’¡ Expert Tip 1
When comparing diamonds of similar weights, always check their measurements. Two diamonds with the same carat weight can vary in dimensions. A diamond with a slightly wider spread will have a larger surface area and appear bigger — often at the same price.
đŸ’¡ Expert Tip 2
Certain carat weights like 0.50ct, 0.75ct, and 1.0ct are especially popular. However, prices can jump sharply at these milestones. For instance, a 0.90ct diamond can be 10–20% better value than a 1.0ct stone of the same quality, while looking nearly identical in size.
What Is Carat Weight?
Carat weight measures a diamond’s weight — not its size.
One carat equals 0.2 grams, about the weight of a paperclip. Carat weight is one of the main factors that determine a diamond’s value.
How Carat Weight Affects Diamond Size
- Shape – Even at the same carat weight, different shapes look different in size. For example, a round diamond appears larger than a princess cut of the same weight.
- Cut – A diamond’s cut affects how it reflects light. A well-cut diamond looks larger and more brilliant than a poorly cut one.
- Appearance – A diamond’s colour, clarity, and setting also influence how big it looks on the hand.
How Carat Weight Affects Price
Carat weight has a major impact on price, but not in a simple one-to-one ratio. Larger diamonds are rarer, which drives the price per carat higher.
Most Popular Carat Weights for Engagement Rings
The most sought-after sizes typically fall between 1.0 and 2.0 carats — large enough to make an impression, yet still accessible.
Ultimately, the best choice is a diamond that feels personal and represents your love story.
Carat Weight vs. Diamond Cut — Which Matters More?
Both play vital roles. Carat weight determines size, while cut determines sparkle. A smaller diamond with an excellent cut can appear more dazzling than a larger one with a poorer cut.
