Ruby

This is a wonderful thumbnail example of the well-known ruby specimens that come from the marble quarries in Pakistan, showcasing excellent quality. The specimen features a sharp, well-formed pseudo-octahedral (trigonal) crystal measuring 8 mm, with a rich pink-red colour and a subtle purple overtone. The crystal sits up high on the bit of white marble matrix. The ruby exhibits decent lustre with sharp, clean faces and good internal gemminess and translucency when backlit. No visible damage is apparent. Additionally, the crystal glows with an intense red fluorescence under long-wave UV light.
