Topaz from
Strickland Quarry (Eureka Quarry), Strickland pegmatite (Strickland-Cramer Quarry; Strickland-Cramer Mine; Strickland-Cramer Feldspar-Mica Quarries), Collins Hill, Portland, Middlesex Co., Connecticut, USA

Locality type:Quarry
Classification
Species:Topaz
Formula:Al2(SiO4)(F,OH)2
Comments:At least one recognizable crystal about 5 cm long was collected by Richard Schooner. Confirmed by Bruce Jarnot, Anthony Albini, and Harold Moritz. Schooner (1958) states that: "There have been reports of topaz...but most evidently refer to the gem quality citrine quartz (the 'topaz' of commerce) which was produced many years ago. Nevertheless, John Tweedy, former operator of the locality, told the author that his company geologist had identified the mineral there in 1953." Later, in Schooner (circa 1985) he says: "Topaz was supposedly verified from the Strickland quarry, at Yale University, a decade ago. It must be quite rare."
Colour:white
Quality for species:Poor for species, only of interest for locality collectors. (#)
Abundance at site:Very Rare
Confirmation
Validity:Confirmed
Confirmation Methods:Visually Identified
