Elbaite from
Gillette Quarry (J-J Mine; Haddam Neck Quarry), Haddam Neck, Haddam, Middlesex Co., Connecticut, USA

Locality type:Quarry
Classification
Species:Elbaite
Formula:Na(Li1.5Al1.5)Al6(Si6O18)(BO3)3(OH)3(OH)
Comments:Hundreds of crystals in some pockets, often "piercing" smoky quartz. Flawless crystals are rare; usually fractured. Large pocket crystals vary but are usually striated to silky, slender and elongated, from small needles up to 30 cm, but typically a few cm long. Color zoning is usually longitudinal, short and terminal in shades of green, pink, golden yellow and blue with up to 5 colors. Antilogous poles typically pale green, yellow, pink; analogous poles usually colorless, pale green, aqua. w/thin indigo cap, or sometimes with a narrow pale colored zone immediately beneath and parallel to the pedion. Tiny crystals may be any color throughout. Concentric “watermelon” zoning is not common. Some fragments of green prisms are overgrown by later pink zones. Also found frozen in matrix with beryl, fluorapatite, fluorite, muscovite, smoky quartz, lepidolite, microlite, columbite.
Habit:Elongated trigonal prisms, antilogous pole terminated with rhombohedral pyramids {1bar11}, analgous pole dominated by a pedion.
Colour:prisms mostly green, blue-green, rarely pink. Terms. green, yellow, pink, blue, combinations
Quality for species:Excellent - world class for species or very significant. (!!)
Abundance at site:Common
Confirmation
Validity:Believed Valid
