|For those celebrating a birthday in October, opal is the traditional birthstone. Opals are one of the most beautiful gemstones and can express every color in the visible spectrum.|

Opal is formed when silica rich water passes through the earth and settles inside cracks and voids within the earths crust. As the water evaporates, silica deposits are left behind. This process repeats itself over a long period of time and eventually and opal is formed. The play of fiery color seen in opal is attributed to light refraction and is due entirely to the uniform size and shape of the silica spheres. Gem quality opal deposits are sourced in Australia.

"October's child is born for woe,
And life's vicissitudes must know,
But lay an opal on her breast
And hope will lull those woes to rest"
