"There is in them a softer fire than the ruby, there is the brilliant purple of the amethyst, and the sea green of the emerald - all shining together in incredible union. Some by their splendor rival the colors of the painters, others the flame of burning sulphur or of fire quickened by oil." ~ Pliny, On Opals.October's birthstone; the opal in its best quality form is more valuable than diamonds. It is said to be the a symbol of hope, happiness and truth. All I know is that I love to watch the dancing iridescent green, purple and gold flecks in the creamy white stone as I wear this ring on my hand.
