I fell in love with this opal as soon as I saw it. Its pattern is exquisite, sometimes it reminds me of an amulet with an eye that sees everything, other times a mountain with its rocks and snow. Undoubtedly it will be beautiful in any jewel you want to make with it. Gemstones 100% Ethical and Natural.

The Opal is associated with good luck, it is the birthstone for October and the gem fo 14th wedding anniversaries.

The name for the opal comes from the Sanskrit word "Upala", meaning precious stone or stone par excellence. The Greek word "opallios" means "to see a change of colors".
