Total Diamond Weight
The carat is the unit of weight of a diamond.
Carat is often confused with size even though it is actually a measure of weight.
One carat equals 200 milligrams or 0.2 grams.
The scale illustrates the typical size relationship between diamonds of increasing carat weights.

Diamond Cut
The quality of cut is crucial to the diamond's final beauty and value.
Depending on its shape, a diamond’s five parts must have exact mathematical dimensions and
proportions in order to achieve maximum diamond light performance.

Fluorescence
Because of all the uncertainty around fluorescence causing haziness in sunlight,
we generally will not recommend any diamonds with fluorescence above medium.
The exception is clients who are looking for investment quality diamond like a D IF. In those cases,
we recommend none to faint fluorescence to make sure these premium gems hold their value.
We don't recommend paying a premium for strong fluorescence in I and J color diamonds because
in most cases you won’t see a beneficial effect on color.
