Laser Ruby Facet Rough Lab Created Crystals

These are pieces of vivid pink-red ruby grown for use in lasers.  It has a rich base color that ranges from red to strong red-pink paired with strong red fluorescence. The stones are each labelled with their letter and weight and can be purchased individually.This is the most classic gem produced by science: laser ruby. In a laser it would be cut into a cylinder or pulled into fiber, charged up with photons from the sides and emit a beam of light out of the end--the very first laser was built with a ruby. As you would expect for this requires a very high standard of chemical purity and structural perfection--when energizing a crystal imperfections tend to heat up and explode. Unlike most classic laser rubies which are grown by czochralski pulling this material was grown by kyropolis pulling, which allows for the creation of much larger crystals.  We were really lucky to get our hands on some very fine material from contemporary laser production.  We don't know the full details, beyond
