Why do diamonds sparkle more than other stones?
Diamond is crammed with electrons – no substance you have ever seen has atoms more densely packed – so light pokes along at less than 80,000 miles per second. That’s more than 100,000 miles per second slower than in air. ‘
What is a demantoid Garnet?
Demantoid is the green gemstone variety of the mineral andradite, a member of the garnet group of minerals. Andradite is a calcium- and iron-rich garnet. The chemical formula is Ca3Fe2(SiO4)3 with chromium substitution as the cause of the demantoid green color. Ferric iron is the cause of the yellow in the stone.

Why do gems shine?
If you’ve ever seen a gem appear to glow, you’ve witnessed gemstone luminescence. This phenomenon occurs when electrons in certain atoms of a crystallized mineral absorb energy and then release it in small amounts over time. Some minerals glow or fluoresce under ultraviolet (UV) light, such as some shown here.
Which stone shines in darkness?
The luminescent Bologna Stone (impure barite), which was discovered by Vincenzo Cascariolo in 1602, was sometimes called “lapis lunaris” (“lunar stone”), because, like the moon, it gave out in the darkness the light it received from the sun (Kunz 1913: 168).
