Ludlamite - classic USA locale
Blackbird Mine, Lemhi County
3.9 x 3 x .9 CM (miniature)
new year 2021
A small miniature plate sprinkled with many sharp yellow-green Ludlamite crystals and tiny Pyrites as well. An older specimen from the Blackbird Mine (Idaho) with a label from Dawson's Minerals (California) dealership from the 1961-1979 era. In fine condition the tiny Ludlamites are gemmy and look great under magnification. An affordable example.
Ludlamite - fan crystals
Santa Eulalia, Aquiles Serdan
4.7 x 4.1 x 3.1 CM (miniature)
Late Summer 2018
A rare miniature sized and very fine Ludlamite from the classic locale of Santa Eulalia. Excellent color, condition and with the desirable fan aggregates of crystals standing above the matrix. Most of what is seen from Santa Eulalia are thumbnails (which can be superb) but those too are very uncommon, they were found before 1985. This is a very large (miniature) specimen with fine form, luster and presentation. Between Santa Eulalia and the later Bolivian Ludlamite finds, these are the worlds best for the specie. Many of the Ludlamites from both locales have a rather unstable Sulphide matrix. This one seems to be very solid, stable with no rotting pyrite or other issues.
A choice, very well crystallized plate of green Ludlamite crystals from the classic Blackbird mine. Several old labels (included) date this back to 1960, which was the period when the best Ludlamites in the US were found. The Ludlamites are deep green, sharp, translucent and in clusters, balls and rosettes. A choice US classic of the quality that is almost never seen on the market today. No damage and the matrix has been stabilized to prevent crumbling of the soft Sulfide base.
Outstanding example of the specie from the old classic Idaho locale of Blackbird mine. These are considered to be the best specimens for the mineral and this one is especially choice. Sharp and gemmy crystals are well exposed and nicely perched on the contrasting matrix. No damage seen even under 20X magnification, the crystals reach up to 1.7 CM, and have fine luster. Micros of Siderite and another mineral are noted on a reddish druzy quartz matrix that sets off the green Ludlamites well.
