Birthstone of the month: Opal & Tourmaline

October's birthstone is considered one of the most desirable because it has two stones to choose from - opals which are famous for their "play on colours", and tourmaline known for its wide array of colours.  

Through the ages, Monarchs have treasured opals, both for their beauty and their protective powers.  Traditionally set into crowns and necklaces they were worn to repel evil and protect the eyesight.  The opal has certainly had a reputation over the centuries from the time of The Black Death, when they mainly believed the gem to be the cause of death, thus losing its buying appeal. Then in the Elizabethan period it was deemed a treasured beauty, which was further expressed during Queen Victoria's reign when she gifted opal  jewellery to her children, thus recreating an increase in popularity again.  However, the stone continued to have a mixed reputation, no thanks to the novel Anne of Geuerstein - written by Sir Walter Scott in 1887 - who depicted the opal as an evil stone.

Tourmaline, the alternate birthstone for October, is a gemstone that displays a vast spectrum of colours and is often misidentified as ruby, emerald or sapphire.

Here at Grays you will find a wonderful display of opal and tourmaline pieces waiting to be discovered.
