Pyromorphite (Ref: LL803)

Specimen composed of densely grouped crystals of yellow/green Pyromorphite (nothing but crystals without matrix). Good colored, large Pyromorphites are rare from England. Some information on the locality from MINDAT: 'This property is adjacent to the Roughton Gill mine and exploits the eastward extension of the Roughton Gill (South) vein. It was begun in 1845, and three crosscuts were driven south to cut the vein. Although promising shoots of pyromorphite and cerussite were found early on, the mine proved to be a financial disaster. In the mid-1970's the Cornish mineral dealer Richard Barstow opened a vein exposure near the High Level of the Mexico mine and made a find of excellent pyromorphite of "old time" quality. The locality was subsequently worked by other collectors and further good material was discovered. The site is now backfilled.'
