The Ultimate Guide to Opal Color: Shades, Meanings, and Stunning Hues You Need to Know - RTA

Understanding the Context

What Is Opal?

Opal is a hydrated amorphous form of silica, formed when water dissolves silica and deposits it in rock fissures over millions of years. Its signature feature is play-of-color—the shifting display of flashes of red, green, blue, gold, and violet that dance across its surface when light hits it. This phenomena make opal distinct and highly prized in jewelry.
