What appears to be a white calcite or limestone is the matrix for one of the largest and most well-formed Rubies that I have ever examined. The stone's visible dimensions measure 0.7 x 0.6 x 0.4" (1.8 x 1.5 x 1.0 cm) and it is in excellent condition, showing no human-induced damage. The part of the crystal that is still buried in the rock probably is malformed or incomplete, but what is visible has flat, relatively smooth faces and very well-defined edges that accentuate its pearly luster. It has a deep ruby-red coloration with a tiny hint of violet, and is cloudy and translucent. It glows a rather bright red under longwave UV light, but there was too much interfering "glow" from the host rock to get a good image of this. There are 4 or 5 other visible rubies trapped in the matrix, two of which show considerable damage, but none of these exceeds 0.3" (8 mm) in any dimension. There is also part of a damaged, dark-gray metallic mineral visible that I cannot identify, and a large amount of muscovite, some of which permeates the host rock in thin, parallel veins. It is a beautiful Ruby that is well-exposed and easy to examine.
