Mimetite

📍Mount Bonnie Mine, Grove Hill, Victoria-Daly Region, Northern Territory, Australia
Dimensions: 26 / 26 / 22 mm

This is a rare specimen of Mimetite from the famous Mount Bonnie Mine in Australia’s Northern Territory, a locality renowned for producing some of the world’s finest examples of this species. The larger crystal, about 1 cm across, exhibits the typical hexagonal form with sharp terminations and excellent symmetry. A smaller crystal nearby, though more modest in size, is equally well-formed and displays the same vivid lemon-yellow luster, making it a quintessential representation of this historic locality.

The crystals are firmly anchored to a contrasting limonite matrix whose warm reddish-brown tones emphasize the brightness and color of the mimetite, creating an especially attractive composition. On the back of the specimen is a small natural vug containing a few additional mimetite crystals—a delightful detail for collectors who enjoy exploring hidden features.

Mimetite from Mount Bonnie is highly prized for its sharp crystal form, high luster, and historical significance. Since production occurred only briefly between the 1970s and early 1980s, fine surviving specimens are exceptionally scarce, making this piece a classic and outstanding representative of the locality.
