Ludlockite is another of the very rare mineral species for which the Tsumeb Mine is renowned and the Type Locality. This very fine thumbnail has superb sprays of bright coppery red-orange, felt-like, acicular ludlockite needles on germanite matrix. A super accessory mineral, a glassy, red zincian siderite rhomb is on the lower right hand corner of the ludlockite. Ex. Ed Ruggiero Collection, who purchased this rarity from the Zweibels in 1976.
