"Carat"

“Carat” is the unit which is used internationally to measure the diamonds weight, a carat is 200 milligrams (0.0004409 pounds), and many times the professionals will refer to a diamond which is less the one carat in “points”, meaning 0.37 carats will equal 37 points etc.

It is also important to know that the bigger the diamond is the more expensive it is, not just because it’s bigger, but also because it’s rare, so a 1 carat diamond will be more expensive then 10 diamonds which are 0.10 each (not like gold for example that 10gr have the same per Gr price like 1 kilo).

It is also important to notice that 2 diamonds which are each of 1 Carat can be in 2 different sizes. Just like you can have 2 friends that weight the same, and yet one is taller than the other )because he is skinnier(, so to diamonds have diameter and height, and even if the diameter is the same it is possible that the height is different, therefore the height and diameter have to be equal for two diamonds to be the same (this subject will be discussed more in the “Cut” subject).

The Carat unit is also used to determine the purity of gold, but we’ll leave that for later.
