9.12ct Mexican Contra Luz Opal

Mexican Contra Luz Opals are a unique variety of opals known for their mesmerizing play of colors and stunning optical phenomenon called "contra luz." "Contra luz" is a Spanish term meaning "against the light," and it refers to the way the opal displays its colors when held up to a light source.
Unlike traditional opals, which showcase vibrant colors when viewed from certain angles, Contra Luz Opals exhibit their play of colors when the light source is positioned behind the stone. This creates a captivating and ethereal effect, with the colors seemingly glowing from within the opal.
What makes Mexican Contra Luz Opals particularly special is the mix of colors they display. They often exhibit a range of warm tones such as oranges, yellows, and reds, with occasional hints of green and blue. The play of colors can vary from opal to opal, making each stone a unique and one-of-a-kind treasure.
This big stone weighs 9.12ct and measures 19x15.5mm. It would look absolutely amazing set in platinum or white gold.
