This is an indentation in glass made with a pyramidal diamond tip (called a Vickers indenter) as part of a lab in CEE 364 Materials in Civil Engineering. The goal was to make a flaw of controlled size and measure its effect on the strength of the glass—but the result was a thing of beauty. The color results from crossed polarizers that indicate the shape of the stress distribution.
