A majestic amethyst geode with snow-white quartz crystals growing inside. An impressive curved section of a geode, with a sparkling bed of violet and white crystals. - Height: 445 mm - Width: 225 mm- 8878 g - (1)

We present to you a geological masterpiece from Brazil: a monumental section of Amethyst geode, weighing over 8.8 kg, distinguished by the rare and spectacular secondary growth of colorless quartz crystals. This specimen is not just a mineral, but a true natural sculpture, destined to become the centerpiece of any collection or setting. The piece’s form is extraordinarily dramatic. The basaltic host rock has been cut away to reveal a deep arched cavity, giving the specimen a dynamic and elegant appearance. This unique configuration maximizes the exposure of the crystal surface, allowing light to penetrate and dance among the countless points. The main bed is composed of thousands of amethyst crystals in a deep, saturated purple. Their brilliance is exceptional, and each crystal, with its perfect terminations, contributes to a sparkling surface that catches the eye. The deep violet hue evokes a sense of luxury and mystery typical of the finest Brazilian amethysts. What makes this specimen exceptionally rare and desirable are the magnificent “flowers” of colorless quartz (rock crystal) that bloom on the surface of the amethyst. These clusters of white-translucent quartz create a breathtaking chromatic contrast with the purple beneath. The quartz crystals are sharp, well-formed, and of notable purity, appearing as floating crystalline islands on a violet sea. This double crystallization tells a fascinating geological story: after the amethyst formed, a change in the hydrothermal solution conditions allowed the deposition of this splendid pure quartz, a rare event that adds substantial scientific and collecting value to the piece. With its imposing size and unrivaled beauty, this specimen is ideal for display as a centerpiece in a salon, a professional study, or a private gallery. It is a work of art created by the Earth, an investment in beauty and rarity that will continue to captivate for generations.
