When looking at the pavillion of a princess cut diamond at 15 power from the side opposite a black girdle inscription. Are the refractive properties such that you could read the inverted backward inscription reflecting off of a pavillion facet in the right lighting?

In a round diamond you often can see (from the side) a reflection of the girdle as a horizontal line part way down the pavillion. I imagine any inscription would be scrambled due to the faceting and not be able to be read.

jacksa Rough Rock Total Posts: 6 Last Post: 1/17/2004 Member Since: 1/15/2004	thanks for your thoughts. I could definitely read it--though inverted and backwards--confusing, although I don't consider myself even remotely competent in physics or light refraction. anyone know any good websites which discuss princess cut light refraction? Thanks.

The inside of a diamond is a lot like a room full of tiny mirrors all lined up symmetrically so that the light will bounce around within the diamond and then exit through the top... Thus inclusions and occasionally an inscription is likely to reflect. Todd L. Gray, President NiceIce.com
