About Ruby as a Gemstone
Ruby is the red gem variety of corundum, coloured by chromium replacing a small fraction of the aluminium in its structure. The same chromium that produces the red also causes fluorescence, which can make fine ruby appear to glow in sunlight. Stones too light in tone are classed as pink sapphire. You can read more via gemmological reference, mineral data.
Ruby forms in marbles produced where limestone is metamorphosed, and in basalt-hosted deposits. The chromium needed for red is rarely found alongside aluminium in nature, which is a large part of why fine ruby is scarcer than most other coloured gems.

The pear cut combines a rounded lobe with a sharp apex, creating a teardrop silhouette that elongates the finger when aligned along the band.
