his remarkable large cabochon of included quartz from the Kharan District of Baluchistan, Pakistan features one of the finest examples of a single prismatic brookite crystal in quartz we’ve ever encountered—an absolute pinnacle piece for any inclusion aficionado or connoisseur of mineralogical phenomena.

Weighing in at 103.47 carats and measuring 44mm x 30mm x 11mm, this gem-quality quartz hosts a strikingly sharp and well-formed brookite crystal, dramatically suspended in perfect clarity like a relic frozen in time. The brookite itself exhibits a metallic sheen and strong internal definition, set vertically within the stone like a cosmic antenna—an axis of crystallographic symmetry.

But what truly elevates this piece is the network of chatoyant, golden-to-coppery rutile needles growing epitaxially off the brookite on twinning planes. These fibrous rutile inclusions catch and scatter light in dazzling flashes, creating a cat's eye-like shimmer that dances across the surface of the cabochon as it’s rotated. The rutile displays classic epitaxial growth behavior—where one mineral grows on another in a crystallographically aligned fashion—enhancing the dimensionality and optical complexity of the piece. The result is a dynamic, living interplay between stillness and movement, between structure and chaos.

This type of formation—brookite with epitaxial rutile in quartz—is already rare, but the clarity, size, and perfection of this specimen push it into a category of its own. The quartz is nearly water-clear, acting as an ideal lens to observe the inner mineral drama in high resolution. It’s not only a showcase of nature’s precision but a metaphysical amplifier—a beacon for collectors who appreciate the inner life of minerals as much as their surface beauty.

This is a true masterwork of the Earth—raw material transmuted by time, pressure, and elemental elegance into a singular work of natural art.
