PYRROTHITE on DOLOMITE

ISSOM RL RENISON MINE TASMANIA

From the ren deep section of the mine and discovered in 1989. It was a big discovery. This is maybe the only specimen left on the market; at least it is one of the better specimens. Classic hexagonal crystals up to 10 mm.

Pyrrhotite is a common magnetic mineral made of iron and sulfur, known for its bronze-brown color that often appears tarnished. It is an important source of nickel and has played a key role in iron production throughout history. However, pyrrhotite is also notorious for causing problems in concrete, especially in areas like New England, where its oxidation can lead to expansion and cracking in foundations. Often called "magnetic pyrite," this mineral has a shiny metallic appearance, a grayish-black streak, and a hardness of 3.5 to 4. You can find pyrrhotite in igneous and metamorphic rocks, as well as in hydrothermal veins, where it usually occurs with other minerals like pentlandite, pyrite, and chalcopyrite.

HELLYERITE (discovered in 1958)

NiCO3·6(H2O) is a type of hydrated nickel carbonate mineral. It appears in colors ranging from light blue to bright green and has a hardness rating of 2.5. This mineral has a shiny, vitreous luster and leaves a white streak when scratched. It crystallizes in the monoclinic system, forming flat, platy shapes and mammillary encrustations on its surface. According to X-ray crystallography, it is classified as a pentahydrate, consisting of subunits made up of [Ni2(CO3)2(H2O)8] along with an additional pair of water molecules for hydration.

This specimen is from the typo locality (this is the locality where it was discovered): the LORD BRASSEY MINE in TASMANIA

BRAVOITE (A VARIETY OF PYRITE).

This specimen origintes from the MMG MINE in Tasmania. Bravoite was first classified as a separate mineral. But nowadays it is seen as a variety of pyrite with a high nickel content.

BUY ONE, GET TWO.

Isn't beautiful? Some minerals reveal a hidden world under ultraviolet light. When exposed to UV, they can fluoresce in vivid colours—greens, blues, reds, or oranges—caused by trace elements or structural defects in the crystal. What looks ordinary in daylight can become spectacular in the dark, showing that a mineral often has more to tell than meets the eye.

💎 Hidden Treasures of Tasmania: The Minerals of the Kara Mine 💎

Tucked away in the rugged, mist-covered hills of northwest Tasmania lies one of Australia’s most fascinating mineral localities: the Kara Mine. For collectors and mineral lovers, this site is nothing short of legendary.

The Kara Mine was developed in the late 1960s primarily as a tin mine, but what truly made it famous was what came with the cassiterite. As mining progressed deeper into the skarn system, pockets rich in beautifully crystallised minerals began to appear—many of them unexpected, and some of world-class quality.

✨ What makes Kara so special?
Kara is renowned for its superb cassiterite crystals, often sharp, lustrous, and sometimes beautifully twinned. Alongside them occur striking fluorite, scheelite, quartz, pyrrhotite, chalcopyrite, and a suite of rarer skarn minerals. The combination of tin mineralisation with complex contact-metamorphic geology created a mineralogical diversity that still excites scientists and collectors alike.

📜 A short chapter of mining history
During its active years, the Kara Mine produced not only tin concentrate but also some of the finest cassiterite specimens ever found in Australia. Many classic pieces entered museum collections and private hands during this period. When mining ceased, access to fresh material became extremely limited—making Kara specimens increasingly sought after and appreciated today.

🪨 Why collectors love Kara Mine minerals
• Strong aesthetic appeal
• Scientifically important locality
• Finite supply – no new production
• A cornerstone of Australian mineral collecting

At Crystals2Collect.com, we are proud to offer authentic mineral specimens from the Kara Mine, carefully selected for quality, character, and provenance. Whether you are an experienced collector or discovering Tasmanian minerals for the first time, Kara Mine pieces are true conversation starters—and pieces of Australian geological history.
