Ideal proportions

With good proportions, you can obtain a diamond with a brilliance that highlights the precious stone. The point is not the size of the diamond, but how the diamond is cut.

It is the effort of the craftsman during every stage of the fashioning process that reflects the maximum amount of light back to the eye. Facets must be perfectly adjusted; a round diamond (brilliant full cut) has 58 facets.
