1. Square Diamond:
- If you have a square diamond, the formula for finding its area is:
```
Area = Side Length²
```
- This formula means multiplying the length of one side of the square by itself.
2. Rectangular Diamond:
- If you have a rectangular diamond, the formula for finding its area is:
```
Area = Length × Width
```
- For a rectangle, you need to multiply the length by the width.
Make sure you use consistent units of measurement throughout your calculations (e.g., millimeters or carats) to get the area accurately.
