What are the 4 C’s of Diamonds?
The 4 C’s of diamonds are a set of criteria used to evaluate the quality and value of a diamond. These four characteristics are:
H1: Carat
- What is Carat?: Carat is the weight of a diamond, with larger diamonds being more valuable.
- How to Calculate Carat: The carat weight of a diamond is calculated by dividing its weight in grams by 200.
- Significance of Carat: A larger carat diamond is more valuable, but it also means more weight, which can be more expensive to cut and polish.

|---|---|---|
| 0.25 | $300-$500 | 0.25-0.5 carat |
