A top gem with an excellent size, perfect for a centerpiece, and outstanding luster. The laboratory has also recognized it as a “Fine Color Quality” gemstone.
Unique to opal, the “play of color” refers to the attractive flashes of colorful brilliance that change depending on the angle of observation. An opal displaying three or more hues in its play of color is called a “multicolor” opal. October’s birthstone, opal derives from the Greek word “opallios,” meaning “to see a change.”

IMPORTANT: The pictures were taken under white and yellow light, with magnification and on different backgrounds, to display the gemstone as accurately as possible. We have done our best to capture its true colors and luster, but slight variations may occur. Kindly review all pictures carefully for a better impression.
