This remarkable completely natural and unpolished Lemurian Quartz comes from the Alegre Mine in Brazil. It was the only naturally double-terminated crystal found within an approximately 400 kg lot of Lemurian Quartz.
Its elongated form, terminations, and surface features are entirely natural—this crystal has not been cut, shaped, or polished. Characteristic horizontal growth striations extend across its faces, preserving the natural growth patterns associated with Lemurian Quartz.
What makes this specimen especially notable is the context of the find. Among approximately 400 kilograms of Lemurian Quartz, this was the only crystal found with this naturally double-terminated formation.
Elegant and unusually slender, the crystal retains its original growth surfaces, natural terminations at both ends, and subtle internal character—a fascinating example of natural quartz formation from this Brazilian locality.

This vibrant ammolite specimen showcases the spectacular iridescence that has made this gem one of the most coveted fossilized organic materials in the mineral world. Layers of naturally transformed aragonite create a dynamic play of color—rich reds, golds, greens, and occasional flashes of blue—each shift revealing the intricate structure of the ancient ammonite shell from which it formed.
Sourced from one of Canada’s most renowned ammolite-producing regions, this specimen displays exceptional color intensity, clean surface structure, and a striking mosaic pattern that responds beautifully to light. Its polished face enhances the depth and saturation of the chromatic layers, making it an eye-catching choice for display or collection.
Ammolite forms through the mineralization of ammonite fossils over millions of years, resulting in a rare gemstone valued for its geological heritage and visual impact. This piece stands out for its luminous sheen, strong color play, and refined presentation—ideal for collectors of rare minerals, fossil gemstones, and natural display material.
A Certificate of Authenticity is included to verify that this ammolite was ethically sourced and legally harvested. As a protected Canadian resource, genuine ammolite requires proper permits for both extraction and export, ensuring only documented and responsibly obtained specimens reach the market.
