✨ October’s birthstone: Opal ✨
One gemstone, so many personalities. From the deep, electric colours of Australian black opal to the soft glow of white and crystal opal, earthy Boulder opal, translucent jelly opal, Ethiopian opal and fiery Mexican fire opal — October has a beautiful spectrum to choose from.
Opal is a hydrated form of amorphous silica, and its famous play-of-colour is created by the diffraction of light through microscopic silica spheres. Its body colour and pattern can vary dramatically depending on its type and origin, making every opal wonderfully individual. 🌈
Which type of opal would you choose?
