Understanding Carat Weight
Carat refers to a diamond's weight, not its physical size. However, cut and shape play a huge role in how large the diamond actually appears.
Price Per Carat
Diamond prices do not increase linearly. A 2.00 ct diamond does not cost twice as much as a 1.00 ct diamond; it can cost 3x or 4x more because large diamonds are exponentially rarer.
"Magic Sizes" & Savings
Diamond cutters try to keep stones above "magic weights" like 1.00ct or 2.00ct because the price jumps significantly at these marks.
Insider Tip: Buy Shy
A 0.95 carat diamond looks virtually identical to a 1.00 carat diamond but can save you 20-30% in price.
Diamond Carat Weight: Size, Appearance & Value
Carat is the unit of measurement used to describe a diamond's weight, not its size. One carat equals 200 milligrams (0.2 grams). While carat weight influences a diamond's price significantly, two diamonds of equal carat weight can appear very different in size depending on their cut, shape, and proportions. Understanding carat weight helps you make a smarter choice for your budget and aesthetic preferences.
Carat Weight Tips
- Consider your finger size — a smaller hand makes a 1.0 carat diamond appear larger, while a wider hand may call for a larger stone.
- Carat weight is not the same as visual size — cut quality matters more. An excellently cut 0.9 carat diamond can appear larger than a poorly cut 1.0 carat.
- The most popular choices for engagement rings range from 1.0 to 1.5 carats, offering a balance of presence and value.
- Buying just below whole or half carat marks (e.g., 0.9 ct instead of 1.0 ct) can save 10–20% with virtually no visible difference.
