| Phenakite strongly resembles fractured quartz and is named from the Greek
word for a DECEIVER. The shape is in the form of the
mystic Pentagon, the grand symbol of constancy and durability. It
is found in pegmatites with quartz, beryl, and chrysoberyl. It is nearly
always colorless or white. An uncommon mineral, especially in crystal forms.
Fine crystals have come from pegmatite in the Crystal Peak area of Park
and Teller counties, Colorado; Anjanabonoina, Madagascar; Sverdlovsk, Ural
Mountains, Russia; and especially at the São Miguel de Piracicaba
mine, Minas Gerais, Brazil in euhedral crystals up to ten centimeters. |
