How is diamond carat defined?
Carat is a unit of measurement that indicates the weight of a diamond, directly influencing its size. Two diamonds with identical carat weights can vary in appearance depending on their shape and the quality of their cut. Generally, carat serves as a reliable gauge of a diamond’s size. Denoted by the abbreviation ‘ct’, carat is a standard unit used not only for diamonds but also for other precious gemstones such as rubies, sapphires, and emeralds, where 1 carat equals 0.20 grams.
What is the origin of the carat system?
The term “carat” originates from the word “carob”. In ancient times, gem traders used carob seeds because of their consistent weight, approximately 0.20 grams, to balance their scales. This practice led to the adoption of the carob seed’s weight as a standard unit for measuring gemstones. Today, 1 carat (ct) equals 0.20 grams, the same weight as a carob seed, although modern scales used for weighing diamonds are highly precise and advanced.
How does diamond size change with carat weight?
As the carat weight of a diamond increases, so does its size. However, diamonds of the same weight can appear different due to variations in shape, cut quality, and individual characteristics. Nonetheless, carat weight provides a general indicator of a diamond’s size, allowing for rough estimations based on this metric.

How does carat weight affect the cost of a diamond?
Diamond prices rise significantly with increasing carat weight, often showing exponential jumps in value. Larger diamonds are notably scarce, making a single large stone more valuable than two smaller ones with an equivalent total carat weight. Refer to our diamond carat vs price table below to observe how prices escalate with carat weight, particularly noting substantial increases at key weights like 1 carat. Our table also compares prices between lab-grown and natural diamonds.
| Carat | Natural Diamond | Lab Diamond |
|---|---|---|
| 0.50ct | £1,500 to £1,750 | £900 to £1,200 |
| 0.75ct | £3,000 to £3,200 | £1,200 to £1,400 |
| 0.90ct | £5,000 to £7,500 | £1,500 to £1,800 |
| 1.00ct | £6,200 to £9,000 | £1,800 to £1,900 |
| 1.50ct | £12,000 to £16,000 | £3,000 to £3,500 |
| 2.00ct | £24,000 to £28,000 | £3,600 to £6,000 |
Instead of fixating on a specific carat weight, it might be more practical to first establish your budget. Focus on prioritizing the diamond’s cut and color grade, which have the most noticeable visual effects, followed by clarity. Then, see which carat sizes fit comfortably within your budget rather than stretching it to meet a particular weight. For instance, you can likely find high-quality diamonds ranging from 0.10 carats within ranges like 0.60 to 0.70 carats or 0.90 to 1 carat that align with your personal budget.
What are the ideal diamond carat sizes?
In diamond carat weight, significant price increases often occur at specific intervals known as “magic numbers”. These intervals typically occur at 0.25 carat increments, such as 0.50 carats, 0.75 carats, 1 carat, 1.25 carats, 1.50 carats, 1.75 carats, 2 carats, and so forth. For instance, a 0.97 carat diamond will generally be priced lower than a 1 carat diamond due to this pricing trend. The most notable price jumps are observed at full carat increments like 1 carat. There are also other carat weights, such as 0.90 carats, which may see slightly less significant but still noticeable price increases.
How do smaller diamonds help reduce expenses?
In the diamond industry, standard carat weights increase in specific increments known as “magic numbers”, such as 0.50 carats, 0.75 carats, 1 carat, and beyond. These thresholds are critical because diamond prices often experience significant increases at these points, prompting many diamond cutters to target these weights. If you come across a diamond that falls just below a magic number, it can offer excellent value for money. For instance, the visible size difference between a 0.97 carat and 1 carat diamond is minimal, yet the price difference can be substantial.
What does TCW indicate when referring to diamonds?
In addition to the carat weight of a single gemstone, jewelers frequently use the term “total carat weight” (abbreviated as ‘TCW’). This refers to the combined weight of all diamonds or other gemstones included in a single piece of jewelry. For instance, in a diamond halo engagement ring, the total carat weight includes the central stone as well as the surrounding stones. Similarly, a pair of diamond earrings’ total carat weight is calculated based on the combined weight of both earrings in the set.
