Dimensions: 60 mm x 45.4 mm x 23.5 mm
"Rutherford Moonstone"; white albite displaying that beautiful, electric blue schiller. Lapidary quality material available on the dumps became harder and harder to find over time. but we still managed to find enough rough to cut and polish...
Collecting there at that time was limited to Labor Day Weekends, in conjunction with a little show that the Amelia Academy hosted, and we always looked forward to those trips.
Smallest piece measures 33.85 x 21.1 x 13.8 mm.
6VW-NHWAlbite Na(AlSi3O8) , Albite (Var: Albite Moonstone) Na(AlSi3O8)
This is a shirt-button sized cabochon of peristerite albite from a little brooklet on Dennis Hill in Litchfield, Maine. Field view 1.5 cm. It shows the whitish blue adularescence typical of the locality. I cabbed this in 1995 using a leather lap and cerium oxide for the final polish. The very small greenish laths are biotite.
J88-AURNepheline Na3K(Al4Si4O16) , Albite (Var: Albite Moonstone) Na(AlSi3O8)
A 2 cm polished section of the sodalite/cancrinite phase of the Litchfield nepheline syenite pluton at Dennis Hill, Litchfield, Maine. The gray mineral on the left is nepheline, which grades towards the right into pale blue albite. At the far right, the albite displays a schiller effect, which is very common in the Litchfield syenite and makes it good for cabochons. The black specks are tiny slivers of biotite.
