Colourful October: Month of Opal and Tourmaline

Whether you live in the Northern or Southern hemisphere, October is a month full of colours, and to celebrate it we have two beautiful birthstones: Opal and Tourmaline. These may not be the most famous or popular gemstones, but they have some unique characteristics.


Opal, the kaleidoscopic gem, is known for its peculiar play of colour, the colours of the rainbow and other gems together in one stone. Many writers have compared opals with firework and galaxies.

Mostly found in Australia, and its national gemstone, opal contains around 5 to 20% water. The colours are a result of the reflection of light through the silica spheres that form precious opal.

It is a delicate stone ranging from 5.0 to 6.5 points in hardness; therefore, it is not the best choice for an engagement ring but a great choice for a cocktail ring, pendant or earring studs.

Opal is also the gift stone for the 14th anniversary of marriage.

Tourmaline exists in almost every colour, that is why in ancient times it was mistaken with other best known gems.

Its roots go back to the 1500s, when a Spanish conqueror in Brazil found a green tourmaline but confused it with emerald.

It can be found principally in Brazil, the area of Paraiba is famous as a source of spectacularly intense tourmaline colours. The US still produces in the area of California, and red tourmaline is supplied by Afghanistan and Madagascar.

It ranks 7.0 to 7.5 points in hardness making it a good option for a cocktail ring.
