Description from the seller
Opal Oval-Shaped Cabochon – Fine Color Quality
Weight: 7.45 ct
Size: 15.33 × 11.99 × 8.10 mm
Color: Light orange base with a vivid play of colors
Luster: Multicolor
Treatment: No indications of treatment
ALGT Certificate Report No. 85608951
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.”
Shipment will be handled by a reliable service provider, fully trackable and insured.
Duties and taxes are the buyer’s responsibility.
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.
