GEMSTONE EDUCATION SIZE
Carat and Size
When speaking about the size of gemstones, it is common to refer to the carat weight.
However, this does not give an accurate picture as some gemstones may have a high carat weight but still be quite small.
This is because some gemstones have a higher density than others (mass per unit volume.)
The dimensions of a coloured gemstone are a good way to compare sizes accurately.
The Diamond Exchange will provide you with all the details relating to your gemstone so you can compare with confidence.
