Found only in the Poncio Mine, Amethyst Geodes with Crown formations are a very rare form of Amethyst where the crystal points form a regal crown-like structure, elevating them from the usual druzy formations, a rare and highly regarded amethyst that is ready to find a top spot in your collection, decor, or gallery. The crown Amethyst is the main highlight of this specimen, the points face forward and are naturally decorated with tiny Golden Goethite needles, creating an overall sparkly brilliance that dazzles the eyes. Another special characteristic is the exquisite beauty of its Amethyst matrix, which has been expertly polished to accentuate its natural colors and drawings. It is a double-sided slice and we chose a 360º rotating base, that way you can easily see the beauty of both sides. A project that started with the raw amethyst agate geode...

17th century Italian 'Florence Fragment' mounted with fossil agate coral and adorned with red phantom quartz crystals, and chalcedony rosettes on polished agate base. This fragment is originally from a historical church in Florence. It was found and saved from the historic Florence Flood of 1966. It is part of a very important and rare collection called The Florence Fragment Collection which previously exhibited with Museo de’ Medici in Florence, Italy. This is a collection of historical fragment artifacts found and saved from the infamous Florence flooding of the Arno River in 1966 which was the worst flood the city had faced since the Renaissance. Fossil agate coral is mounted on top of the artifact. Fossil agate coral is Florida's state stone and is known for its unique formation that can take place over 20 million years. It's a natural gemstone that is created when prehistoric coral is gradually replaced with agate. It is adorned with coordinating red phantom crystals and chalcedony rosettes that resemble the color and texture of the piece. The piece has been naturally distressed from the flood. It has been preserved and transformed by Jean O'Reilly Barlow, the creative director of Interi. The date of manufacture reflects when she created the piece and the period shows that the Italian fragment is originally 17th century. The story and history of this piece and Interi's collection of Florence fragments...

A Superb Blue Lace Agate with a Rarely Seen Combination of Colors and Drawings ▫️ Description A superb slice of agate, this delicate specimen displays geological artistry. This Soledade Agate showcases intact banding in rare blue, bronze, and clear color hues—a truly artistic expression from Mother Nature. Over millions of years, layers of agate formed continuously. Hundreds of tiny bronze and deep blue bands create a frame, while the clear crystal provides the necessary empty space for the agate's central drawing to emerge. Special mention must be made of the central drawing, where rare blue, black, and cream colors form a microscopic landscape, reminiscent of icy terrain or coral formations, with sparkling druzy accentuating its intricate details. This thin slice of agate is translucent, and as you can see in the pictures, backlighting enhances and alters the color perspective of the agate, bringing out a blossoming golden hue. It is a perfect display specimen to place near a window, allowing you to witness the agate's transformation from an icy, cold appearance to a fiery, rich landscape throughout the day. With no cracks and no treatment at all, the agate is of super-extra, gallery grade. This breathtaking blue lace agate slice is a true collector's piece. With details visible from both sides, it's sure to become a part of your crystal collection. Check out the close-up photos to admire the intricate banding and delicate color hues. Have questions? Feel free to send us a message! Have you ever wondered how these mesmerizing blue lace layers formed? Agates typically form within gas bubbles or cavities in igneous (volcanic) rock like basalt. Over time, these cavities fill with layers of silica-rich water. As the water slowly evaporates, it leaves behind a layer of silica gel, which eventually hardens into a solid layer. This process repeats, with each layer potentially containing different impurities that contribute to the variation in color we see in the agate's bands. It's a remarkably slow process, and the result is truly fantastic, right? ▫️ Blue Lace Agate Slice on Stand...
