What Is Diamond Carat Weight?

Carat weight refers to the physical weight of a diamond. One carat equals 0.2 grams, about the same as a paperclip. Carat can also be measured in points, where 100 points equal 1 carat (e.g., 0.50 carats = 50 points).

While carat affects how large a diamond appears, it’s not the only factor. Cut quality and shape also influence a diamond’s perceived size and brilliance.

How Does Carat Weight Affect a Diamond?

1. Appearance
  • Larger carat weights often stand out and attract attention.
  • Cut quality can make smaller diamonds appear larger or more brilliant than poorly cut larger stones.
2. Price

Price increases exponentially with carat due to rarity. For example, a 2.00ct diamond may cost significantly more than two 1.00ct diamonds combined.

3. Setting & Style

Larger stones require sturdier settings. Smaller stones allow for intricate designs and are commonly used in halos or pavé settings.

How to Choose the Right Diamond Carat

1. Consider Your Budget

Carat weight is a major price driver. Consider stones just under popular carat milestones (like 0.90ct vs 1.00ct) — visually similar but more affordable.

2. Match the Setting

Certain settings, like a halo, can make smaller diamonds appear larger. Choose a setting that enhances the carat visually if you’re working with a smaller stone.

3. Consider Lifestyle

Larger diamonds may catch on clothing or feel bulky for daily wear. Choose a size that fits comfortably with your lifestyle.

4. Let Taste Lead

Some prefer large diamonds; others value clarity and cut more. At Stienhardt & Stones, we offer a curated selection for every preference and style.
