NMM 2582 is a large ~0.3 mm olive green V-type (vitreous, glass).
NMM 2582 - Nesodden
In the front, a huge golden nickel-iron metal bead has triggered conical crystallisation, covering approximately one-third of the stone. The metal is surrounded by a thin sulfide rim, so this stone is fresh from Space!
The large metal bead has colourful oxidation (Newton rings) on one side, and the glass has several circular pit erosions, so this stone has it all!
