Estate Mexican Contra Luz Jelly Opal & Diamond Ring

In Spanish, “contra luz” means “against the light” and refers to Mexican jelly opals with a particular type of fire or play of color, such as the gem in this ring. As with most of the kind, this opal has been cut into a high dome cabochon, allowing the gem to capture the light. As the gem moves, the crystal structure of the opal interferes with the light, breaking it into its prismatic colors. It comes alive with a kaleidoscope of pastel blues, greens, reds, and more vibrant colors. At some angles, the opal has a milky, moonstone-like glow; at others, you can see every color of the rainbow. This Mexican opal is set in an estate three-stone white gold ring with delicate diamond accents, crafted in Japan, where rare gemstones are highly valued. If you’ve been looking for an unusual opal, look no further.
