Item Description

Some of the most well known Jelly Opal in the world comes from Mexico. These stones are among some of the biggest, brightest and most intense color Opals from North America. There has been a surge in the price of fine quality Fire Opal / Jelly Opal from Mexico in the last few years, as the material seems to be more and more difficult to obtain. This "Oval Cabochon" cut gem is a beautiful, bicolor (orange and colorless) stone with great "jelly" appearance, but the most impressive aspect of the stone is the fact that it shows the highly desirable and seldom seen color flash or "Contra Luz" effect! Now the color flash is best seen in sunlight or with a strong flashlight against a black background. We tried our best to get the color flash to show up, but it's not there in the photo, but please know it's there in person. When strongly lit, the stone shows flashes of green, red and gold.
