Diamond size, often confused with carat weight, is more accurately represented by its dimensions (length and width in millimetres). While carat weight indicates how much a diamond weighs (1 carat = 0.2 grams), the visual size of a diamond can varies based on its shape and cut. Understanding both carat weight and dimensions is crucial for making informed decisions when selecting a diamond.
Carat vs Size:
- Carat: : Refers to the weight of the diamond, not its physical size.
- Dimensions (MM): Represent the length and width of the diamond, providing a better indication of its visual size.
Diamond Size Charts:
- MM to Carat Conversion: Diamond size charts typically correlate millimetre (MM) measurements with carat weight for different diamond shapes.
- Example: A 6.5mm round diamond is approximately 1 carat, while a 7.3mm round diamond is roughly 1.5 carats.
- Shape Variations: Diamond shapes (round, oval, etc.) have varying MM to carat ratios. For instance, an oval diamond of the same carat weight as a round diamond will appear larger due to its elongated shape.
