This matrix of arsentsumebite, which features lively apple-green color, is full of tiny twinned crystals in striking contrast to azurite, and this combination is one of the most famous and attractive from Tsumeb, and justly so. They make magnificent display specimens and only come from Tsumeb, with an ultimate showing of dramatic color contrast. When placed in a case next to other specimens it really has overwhelming POP and GLOW by comparison.
