Opal is recognized as the queen of all gemstones and is one of the oldest gemstones since ancient civilization. The term opal is thought to be taken from the Sanskrit Upala, which means “precious stone,” and after the Greek derivative “Opallios,” which means to see a change of color. The stone can be found in gray, blue, pink, yellow, and brown colors and looks transparent to opaque in appearance. Ethiopia, Brazil, USA, and Australia are the primary producers of the best quality opals. Opal is a stone for intuition, balancing emotions and purifying our mind and soul soothingly. In addition, Opal is celebrated as a June birthstone and the luckiest stone for those born under the zodiac sign of Libra.
