World-class crystals and exquisite mineral specimens.

Powell Minerals is a premier destination for museum-quality crystals and exceptional mineral specimens, founded by Grant Powell—a lifelong collector whose passion for geology began at the age of five. Raised in San Diego, California, near the legendary Pala mining district, Grant was immersed early in one of the world’s most storied mineral regions. That proximity to extraordinary tourmalines and pegmatite formations sparked a fascination with the natural world that has deepened over decades of dedicated collecting.

Though Powell Minerals operates with the discipline and expertise of a world-class firm, its philosophy is distinctly collector-led. Grant Powell does not view himself primarily as a dealer, but as a steward of rare natural objects. Each specimen is sought, evaluated, and acquired with the eye of a collector—valued for its authenticity, geologic significance, and aesthetic power rather than market trends.

Powell Minerals is grounded in a profound respect for true rarity. Unlike man-made collectibles, minerals are shaped by irreversible geologic processes spanning millions of years. Every specimen represents a singular convergence of chemistry, pressure, time, and chance—an unrepeatable artifact of the Earth itself. This understanding informs the firm’s uncompromising standards and its focus on pieces that embody both scientific importance and natural artistry.

The collection specializes in museum-quality minerals sourced from renowned localities across the globe, each hand-selected for exceptional crystal form, color, and overall visual impact. Whether serving serious collectors, institutional buyers, designers, or investors, Powell Minerals offers a carefully curated portfolio intended to inspire, endure, and elevate the spaces in which these specimens reside.

Operating from a private gallery in Austin, Texas, Powell Minerals provides an intimate and considered experience for clients. The firm offers personalized consultation, custom sourcing, professional appraisal, and comprehensive collection management, as well as museum and trade services including exhibitions, luxury installations, and white-glove global delivery. Ethical sourcing, full provenance, and expert guidance are foundational to every acquisition.

At its core, Powell Minerals exists to connect people with the timeless beauty of the natural world—preserving and presenting Earth’s most extraordinary creations with care, discernment, and reverence.
