Galena pseudomorphs after Pyromorphite (sexangulite variety)
Aerial prismatic crystals of Pyromorphite pseudomorphed by Galena (variety sexangulite), on matrix. An old specimen, a rarity with "pedigree" and subjected to numerous avatars, as evidenced by the extensive accompanying labels. From the collection of Ferdinand Gonnard it went to the École de Mines in Paris, and from there to a German collector whose name was not preserved, to be, later, commercialized and passed successively to Frédéric Bonnet, Maxime Tomljanovic, Thierry Buléon, and Benjamín Carballo. This type of specimen is so difficult to obtain that it is not surprising that it moved through so many collections.
Huelgoat, Châteaulin, Finistère, Brittany/Bretagne France
Specimen size: 3.6 × 2.6 × 1.8 cm = 1.42” × 1.02” × 0.71”
