These were first discovered in 2001 and are found mostly of industrial quality. Though they don't get very large, the color is spectacular. The GIA has written a nice article about these crystals published in Gems & Gemology, Fall 2019, Vol. 55, No. 3.

LL803 - Pyromorphite $ 1200 Mexico Mine, Roughton Gill, Caldbeck, Allerdale, Cumbria, England, UK miniature - 4.5 x 4 x 3 cm ![]() ![]() ![]() ![]() ![]() 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.'
