An unusually distinct and sharp Ferberite that has completely replaced the original Scheelite crystal, retaining the original shape perfectly. From the classic locality at Trumbull, Connecticut that was worked at various time going back to the early 1800's. The entire area is now a park and collecting is not permitted. The locality was the first to be operated for Tungsten in North America and it seems was the first site where Tungsten ore was found in the Americas. The Ferberite here is all tested as nearly pure Fe type (Ferberite). This crystal is unusually sharp and has a tiny bit of adhering mica. A choice old classic USA pseudomorph.

Chrysoberyl Locality, Middlesex Turnpike, Haddam

Late Summer 2018
A small but significant Chrysoberyl from the Haddam Connecticut locality that was the first place the mineral was found in situ in 1810. Mindat offers a detailed report on this long closed locality that makes great reading.
The main Chrysoberyl on this matrix is .8 CM and is sharp, translucent and a good yellow-green. Ex Larry White collection, these old Chrysoberyls are not often available. The collecting was most active in the early to mid 19th century and it seems by 1901 the original spot was no longer accessible. A choice classic thumbnail for this important locality.
