Diamond 4C Diamond Weight (Carat)
For those who are new to diamonds, the term "carat" is probably the most commonly heard but also the most ambiguous concept. This illustration will help you quickly grasp the core knowledge.
1. what is "carat"? Weight, not size!
Many people mistakenly believe that the carat (ct) is a unit of diamond size, but it is actually an internationally recognized unit of **weight**. Remember, carat describes the "weight" of a diamond, not its "height" or "width".
1 carat equals
0.2
gram
1 carat equals
100
Points
2. weight vs visual size
Although carat is a weight, it does have a positive correlation with visual size. This chart compares the carat weight of a common round diamond to the size of the diameter directly above it to give you a better idea of size.
3. "Exponential" growth in prices
Diamond prices are not increasing linearly. A 2-carat diamond costs more than twice as much as a 1-carat diamond because the larger the stone, the rarer it is, and therefore the value increases dramatically, showing an exponential growth trend.
4. Smart Spending Tip: Recognizing Magic Sizes
In the market, rounded weights such as 0.50, 1.00 carat, etc. are known as "magic sizes". When these thresholds are reached, the price jumps significantly. By choosing a diamond slightly below the magic size, there is almost no visual difference, but you can save a considerable amount of money on your budget.
5. Concluding Remarks
Carats are weights.
Remember that 1 carat = 0.2 grams, which measures the weight of a diamond.
Size Diameter
Visual size is mainly affected by the diameter, which is closely related to the cut.
Price Index Growth
Double the weight and the price may increase several times, as rarity determines value.
Make good use of non-magical dimensions
Buying a diamond slightly below a round number is a smart choice for both your eyes and your budget.
