This is a single, doubly-terminated, Ruby crystal measuring 1.5 cm in length. The Ruby has a vivid, blood red color that is amazing, and the color saturation is as good as you can ask for. The luster is superb, growth habit complex, and the crystal ranges from gemmy to translucent. This is a high-caliber, 20 ct. Ruby with brilliant red fluorescence, to boot. This has the waxy luster of a truly typical Mogok ruby, that makes these stand apart from others.
