Krennerite is an orthorhombic gold telluride mineral that may contain varying amounts of silver within its structure. Its formula is AuTe2, although specimens with up to 24% of the gold replaced by silver have been discovered ([Au0.77Ag0.24]Te2). Unlike the chemically similar gold-silver tellurides calaverite and sylvanite, which are monoclinic, krennerite is orthorhombic.

Its color ranges from silver-white to brass-yellow. Krennerite has a specific gravity of 8.62 and a hardness of 2.5. It is typically found in high-temperature hydrothermal environments.

Care

It's important to know that many minerals can be effectively cleaned with water. However, before using any cleaning methods, such as dissolvers or ultrasound, please take the time to research online. Improper use of these techniques could potentially harm your specimen.
