Ruby And The Sun's UV Rays
Many rubies can shine when exposed to
sunlight. Strong beliefs in many societies thought it was due to their magical powers. We
would have loved this answer to be true but they actually glow because of ultraviolet rays.
The sun's UV rays make the chromium shine within the gem. Certain rubies, particularly those
found in marble (from places like Burma or Vietnam), exhibit a strong red fluorescence in
daylight, intensifying the color of the stone and giving it the appearance of glowing red.
Let's have a look at what makes this particular aspect of the ruby so
gorgeous.
The
intensity of ruby's red is determined by the amount of chromium present: indeed, the
more chromium, the greater the red color is. Chromium can also induce fluorescence,
which amplifies the red color.
THE QUESTION
So How Does It Work?
To understand why we have to look into the
internal composition of a ruby. When electrons are excited by a source of radiation, they
jump to a higher degree of energy around the nucleus of the atom. The excited electron stays
in this excited state for a brief period before it slips back to its initial state. When the
electron returns to its ground state, it releases energy either as heat or as visible light.

With over ten years of marketing
experience, I finally decided to settle down in Bangkok to work in an area that I have
always been interested in: the gemstones industry. I'm still learning how the market works
on a daily basis, and I enjoy sharing my experience with those who are interested in
learning more about gems in general.
