Description/Interesting Notes:

A historic, old time example of sphene with actinolite from Tilly Foster!!! This specimen consists of a solid matrix of deep green actinolite crystals in association with clinochlore that hosts a gemmy crystal of yellowish sphene!!! It is difficult to discern in the pictures, but there are actually two crystals of sphene right next to each other, one is a partial crystal, however the other one is complete!!! The actinolite crystals have deep green color with many of them having a certain degree of internal "flash"!!! There are also numerous areas where the actinolite crystals appear to be partial or complete pseudomorphs as well!!! This specimen retains an old University of Pennsylvania label from George Koenig (1844-1913) that notes he acquired it from "Landis" in 1891!!! The specimen also retains its original Seaman Museum label as well!!! The pics hardly do it justice!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!! STAY TUNED!!!
