1TD-HU5Azurite Cu₃(CO₃)₂(OH)₂ , Malachite Cu₂(CO₃)(OH)₂ , Willemite Zn₂SiO₄ , Sphalerite ZnS , Quartz SiO₂ , Hematite Fe₂O₃ , Magnetite Fe²⁺Fe³⁺₂O₄

Andover Iron Mine, Andover Township, Sussex County, New Jersey, USA

Dimensions: 80 mm x 40 mm x 60 mm
Weight: 263 g

Colorless willemite crystals, green malachite, gray-brown sphalerite mixed with colorless/milky massive quartz. In left/center-bottom part of the specimen is a tiny amount of deep blue azurite. Hematite is very visible on the back (not pictured) as an orange-brown area. The magnetite was detected by sticking the magnet to the specimen.

The willemite is fluorescing in SW UV from pale-yellow to orange-yellow to pale greenish-yellow - all are phosphorescent. Not much under LW UV - it is rather very weak (UVGL-58 6 watt lamp).

Excavated from the wall by Mr R.G.Braun in 1970s.
