The name opal evolved from the Roman word "opalus" which traces its roots from the Greek's "opallios " meaning to see a change of color. This Greek word is likewise a revision of the ancient Indian Sanskrit's "upala " which means precious stone. The development of this gemstone started millions of years ago when a mixture of silica and water flowed into cracks and holes in the ground. Over time it hardened and solidified to turn into opal.
