To the naked eye, this ruby specimen is not very exciting. It does have a two dozen ruby crystals in a gray host rock, and the ruby crystals are a dark red and at least some of them are well-formed. They are only slightly translucent, and, for the most part, they have a dull luster. However, under long-wave ultraviolet, the ruby crystals glow with a bright laser-red glow (the first laser was a ruby laser, back in 1957). The fluorescent image does not do justice to these rubies, as they look a bright deep red under long wave ultraviolet.
