Duftite is a colorful mineral found in the oxidized and weathered zones of Sulfur ore deposits. Its color is certainly green, but apparently there is great confusion as to what shade of green. I have come across the following descriptors: pea-green, apple-green, gray-green, olive-green, lime green and dark green. So we know it’s green, and I’ll leave it up to you to determine the exact shade! Its luster is also varied, including sub-vitreous, resinous, waxy and dull. This green mineral is often associated and paired with Calcite, Dioptase, Cerussite, Malachite, Azurite and Quartz to name a few.
The crystal system for Duftite is orthorhomic, usually in botryoidal aggregates or microcrystalline crusts. Other forms include small tabular crystals.
Duftite specimens are fairly common. Notable localities include Australia, Germany, France, Namibia and the USA (Arizona).
