Buy Opal Gemstone Online at the Best Prices in the USA
Opal is a unique gemstone that is known for its iridescence and play of colors. Opals are found in a variety of colors, including white, black, gray, brown, and blue, and their colors can range from a deep, vivid hue to a subtle pastel shade. The most valuable opals are those with a strong, vibrant play of colors, which are caused by the diffraction of light as it passes through the tiny spheres of silica in the stone.
