Epidote, Ca₂Al₂(Fe³⁺;Al)(SiO₄)(Si₂O₇)O(OH).

The anisotropy, or directional asymmetry, of epidote causes the stone to appear different colors from different directions. The crystal structure bends light differently depending on the path, appearing to you as a color change.

This picture shows a bluish-green for the crystals on the left, and a more yellow-green on the right.

Today, famed architect I.M. Pei turns 96. Born in Guangzhou, China, Pei came to the United States in 1935 to pursue higher education. He graduated from MIT with his Bachelors in Architecture in 1940 and from Harvard’s Graduate School of Design in 1946. Pei’s work is distinctly modernist with cubist tones and often features distinctive sweeping glass facades. He is perhaps best known for the glass and steel pyramid at the Musée du Louvre in Paris, France—a controversial project completed in 1989 that has since become one of the most iconic modern buildings in France.
