ACTINOLITE
Mary Kathleen Mine, Mt Isa – Cloncurry Area, Queensland,
Australia
When these specimens arrived from Australia I opened the package and
couldn’t believe my eyes! These are very special examples of one of the
asbestiform minerals that actually, occasionally forms euhedral, prismatic
crystals. Detailed descriptions are not really needed for these very
special specimens, yet they do require a little introduction:
Item MI-1550
Very large non-terminated, dark greenish-black Actinolite crystal aggregate
measuring 6 1/2” long, 1 5/8” wide, up to 5/8” thick. No matrix.
Price: $95.00 SOLD
Item MI-1551
Intergrown, pale smoky gray-white Calcite rhombohedrons to near 2” on an
edge serve as the matrix for several large, dark greenish-black,
non-terminated Actinolite crystal aggregates. The Actinolite crystal in
View A is 3 1/2” long X 1 1/4” wide. The Actinolite crystal aggregate in
View B is 3 3/4” long X 2 1/2” wide. The Calcite is not fluorescent.
Overall specimen size: 3 3/4 X 3 1/2” across X up to 2 1/2” thick
Price: $75.00 SOLD |
