WHAT IS OPAL

Opal is believed to have originated in India, which is where the first opals were brought to the Western world, and  was known as Upala, or "precious stone" in Sanskrit. It was called Opalus in ancient Rome. Most Opals are valued for their rainbow-colored shifting hues, known as "play-of-color."

Opal Description (gia.edu)

Play-of-color is a fascinating display of flashing rainbow hues seen in opals. Opals are divided into two categories: precious and common. Play-of-color is seen in precious opals but not in common opals.

Because the precious opal is made up of sub-microscopic spheres arranged in a grid-like pattern—like layers of Ping-Pong balls in a box—it exhibits play-of-color. Light waves diffract, or bend, as they pass between the spheres. As they bend, they split off into spectral hues, which are rainbow colours. The end effect is a colourful kaleidoscope.

WHAT IS TOURMALINE

The newer birthstone for October is tourmaline. Because it typically contains various hues in one crystal, the term tourmaline?? originates from the Sinhalese word toramalli, which means "stone with mixed colours." Tourmaline has a stunning variety of hues that few other stones can equal.
