Diamond Round Brilliant

An ideal cut diamond is a round brilliant cut diamond that’s cut to such precise proportions that the light entering through all sides of the diamond is sent back out of the diamond through the table with maximum reflection and refraction. If a diamond is cut too deep, the light will leave the diamond through the sides and if a diamond is cut too shallow then the light will also leave through the sides and bottom of the stone.

An ideal cut diamond is not possible all of the time, in many cases, the rough diamond’s natural inclusions make it impossible for diamond cutters to apply ideal proportions during the cutting process.
