OCTOBER BIRTHSTONES.

October is counting already and I just thought to myself, why not just write about her birthstones?? So that’s exactly what I’ve decided to do. Individuals born in October get to choose between two birthstones – opal and tourmaline.
The name opal originates from the Greek word ‘opallios’ which means ‘to see a change in colour.’ This October stone occurs in a wide variety of colours and in its most valuable forms display a play of colours that is unlike any other gemstone. Opal’s classic country of origin is Australia. Seasonal rains soaked the parched outback, carrying silica deposits underground into cracks between layers of rock. When the water evaporated, these deposits formed opal. Although opals come in a wide variety of colours, five of the main categories are: white or light opal, black opal, fire opal, boulder opal and crystal or water opal.

Tourmaline comes from the Sinhalese words ‘tura mali’ which means ‘stone of mixed colours.’ This October stone stands apart from other gems with its broad spectrum of colours in every shade of the rainbow. One of this gem’s most impressive traits is its ability to become electrically charged through heat (pyroelectricity) and through pressure (piezoelectricity). When charged, tourmaline can act as a magnet by oscillating and by attracting or repelling particles of dust. Tourmaline is of diverse forms such as: schorl (or black tourmaline), dravite (or brown tourmaline), elbaite.

Opals and tourmalines form a broad range of colour choices and combinations that are sure to dazzle in the month of October. These unique birthstones can be fashioned into beautiful necklaces, rings and bracelets that create a sense of heritage and identity.

Which one do you prefer? Feel free to share your thoughts.
