Crown Angle (5.10)

At 34½˚, the angle of dispersion is at its greatest. At 30˚ one would have to look in a more parallel direction to the table of the diamond to observe...

Pavilion Angle (5.09)

The original ideal pavilion angle is 40.75˚. A steep pavilion angle will allow the light to fall within the  24.5˚ critical angle therefore exiting unnecessarily.

The Critical Angle (5.08)

  The critical angle in a diamond is 24.5˚ which allows that approach of the light to enter the diamond. After the light enters the diamond the 24.5˚ is avoided so it...

Single and Double Refraction (5.05)

Diamond is singly refractive -- but some gemstones are doubly refractive such as alexandrite, aquamarine, citrine, kunzite, corundum (ruby/sapphire), spinel, tourmaline, moissanite etc. Light in doubly refractive gemstones travels at...
