how big is a ct diamond
On the other hand, the size of a .5 carat diamond is approximately 5.2mm. Even though the carat weight is 50% of a 1 carat stone, it doesnât face up twice as small! Likewise, the physical size of a 2 carat diamond (8.2mm diameter) isnât twice as big as that of a 1 carat diamond (6.5mm diameter). Hopefully, this clears up the misunderstanding of carat weight and actual sizes.
