Crown Angle

The crown angle is the angle that’s formed where the bezel facets meet the girdle plane. Most diamonds have crown angles range between 25 and 35 degree angle. Diamond with crown angles shallower than 25 can be quite bright, but they are more susceptible to damage than stones with higher crowns.

Diamonds with shallow crowns should be set in mounting that protect the girdle area, like bezel setting, which surround the sound with a rim of precious metal. Diamonds with lower crown angle are better suited for use in jewelry where they’re less vulnerable to damage, like earrings and pendants.

It has been a challenge for a diamond cutter to cut in a shallow crown & pavilion angle in other to get largest girdle diameter and the highest possible weight retention. They also tend to have larger table percentages and thin girdles.
