Graemite
1 in the gallery
Graemite is a hydrated copper tellurate mineral. It forms small, typically color-rich crystals with a vitreous to subadamantine luster and a pale blue to green hue that can be accentuated by light. Crystals are often tabular or prismatic, sometimes embedded in rock matrices, and can present a delicate, translucent to transparent appearance in well-formed specimens. Notable material comes from parts of the United States, where its tellurate chemistry and copper content create distinctive color characteristics that appeal to collectors seeking unusual copper-oxide influenced minerals.

About Graemite
Collectors prize Graemite for its rarity and the unusual combination of tellurate chemistry with hydration. Specimens displaying sharp crystal faces or well-preserved habit against contrasting host rock are especially desirable, as are samples that reveal clear color zoning or distinctive aggregation. While not among the most common minerals in broader collections, Graemite provides a striking example of tellurate chemistry and copper mineralogy, adding diversity to a mineral lineup and offering a window into oxide-influenced systems that collectors value for study and display.
