Loose Mexican Cantera Opal, dating from the 1980s-90s. This is a Mexican Cantera Opal, a unique type of opal that looks like it has captured neon colors within a fossilized egg. It exhibits the characteristic play-of-color of opals, and this particular stone has a prominent purple play-of-color, which reflects light and shimmers as you change the angle, offering a delightful visual experience.

About Cantera Opal: Cantera opal refers to Mexican opals that are still attached to their host rock. Their appearance, as if they were sleeping in the earth, evokes a sense of mystery. The vivid colors are a characteristic of precious opals, known as play-of-color, and the appearance of the stone changes as it is rotated. The color also changes depending on the type of light source, making it very attractive. Cantera opals do not have a specific color, but rather the colors created by nature. They are transparent and have a neon-like, vibrant iridescence that changes depending on the viewing angle and light source. Each one is unique, and no two are alike. #Mexico #MexicanJewelry #Opal #NaturalOpal #PreciousOpal #CanteraOpal #MexicanOpal #MexicanJewelry #MexicanOpal #LooseStone #Birthstone Color...Purple Accessory Decoration...Other Stones
