Chrysoberyl -Classic, Co-type locale
Chrysoberyl Locality, Middlesex Turnpike, Haddam
2 x 1.7 x 1.5 (thumbnail)
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.
A classic form for Chrysoberyl showing an inverted V twin well exposed on matrix. From the finds in the 90's at Colatina, this is a sharp crystal in fine condition. Hard to find any of quality on the market now, this has textbook form. Perfect by naked eye, some micro contacting (mostly on the back side) is evident with magnification.
3.6 x 3.3 CM (small miniature/ large thumbnail (toenail))
A very fine prismatic central prism is joined by 2 other smaller "wing" crystals forming one half of the classic sixling twin. The crystals are all glassy yellow-green and gemmy with many inclusions. The central crystal is big at 3.3 CM in size and has minimal damage on the display side. The back of the specimen is contacted and broken but it is not in view from the display side. This is a good piece showing lots of form and character!
