Agatised Geode Slice with Rare Central Calcite Formation and White Quartz

About the Item

Bordered by a thick, blueish agate layer, this wonderful slice preserves an interior of large white quartz crystals with a prominent central calcite. The calcite itself is overlaid in amethystine quartz, in another example of epimorphism, with further pinkish “frosted” quartz projections. This piece was legally and ethically sourced directly in the prestigious mines of Uruguay, South America. Uruguayan amethyst is internationally recognized as being the finest and most aesthetic amethyst in the world, due to its intense deep purple coloration, the large size of its peaked crystals, and its durability. These crystals were formed over 120-140 million years during the Cretaceous period, and as all of our pieces are formed naturally, they are completely unique and unrepeatable natural wonders of art.

  • Studio Greytak 'Lava Mirror 1' White Amethyst, Agate Wall, and Mirror Inset
    By Studio Greytak
    Located in Missoula, MT
    LAVA MIRROR 1 Millions of years ago, volcanoes unleashed rivers of molten lava. As the lava raced around trees and other obstacles, cavities were formed. Air pushed its way into the mass, liquid laced with iron spilled inside, and in one of the slowest dances, the atoms moved into formation then froze, over time, into magical rhombohedrons. Studio Greytak’s Lava Mirror pays homage to one of nature’s most glorious creations with a stunning slice of rare white amethyst, still encrusted with its protective rock shell. Inside the natural cavity left at the center of the original geode, a polished mirror reflects back through its sparkling crystal frame. In eastern and western cultures, the amethyst spins a path to the divine. The six-sided crystal provides a “shield of spiritual light” and aids in communion with sacred realms. Religious leaders, royalty and those seeking enlightenment have always held it close. Buddhists wear rosaries made of amethyst, a stone once sacred to their sage. Bishops in the early Christian church wore rings set with amethyst, and gem-cutters still describe the most precious jewels as “Bishop’s Grade.” The high priest of Israel wore a breastplate with 10 stones engraved with the names of the tribes, the ninth an amethyst.? Peruvians carved...
