The Franklin mines in Sussex County, New Jersey, exploited one of the most complex orebodies on Earth, famed for its diversity of mineralisation and the word capital of fluorescent minerals.  The Franklin mining district is host to 273 recognised species and is type locality to an amazing 49!  This superb small miniature Zincite forms deep cherry red to rich orange red crystals and infillings, all aligned to the foliation of the matrix.  The two crystals form elongated prisms to 1 cm long with parallel prism faces and pyramidal terminations. One of these crystals is more complete than the other and neither are sharply defined.  Despite this, it must be recognised that natural Zincite crystals are extremely rare.  Zincite has two co-type localities, one here at the Franklin mine and the other at Sterling Hill mine at Ogdensberg, at the opposite outcrop end of the syncline-hosted deposit.  The matrix is a mixture of what appears to be white Calcite, although this does not fluoresce, granular black Franklinite and patches of massive green-fluorescing Willemite.  This is a lovely old-time specimen accompanied with three labels.  One is that of Dr Otto Runge of Delaware, dated August 23, 1941 and one is ex. The A.E. Seaman Museum at Michigan Technological University.  This small miniature is mounted on a small bevelled clear acrylic base.
