Fluorescent Mineral Gallery 2 NOTE: The SWUV photos were taken using a SuperBright SW2000 from www.uvsystems.com and the LWUV photos used a UVLS-26P from www.uvp.com. Depending on the type and power of the lamp you use, the fluorescence you get from these specimens may differ from the photos.
TPZ5-03 Topaz,
Fluorite (yellow in SWUV!) and Un
San Mine, Hunan Province, China
A shard of matrix is enveloped on both sides by beautifully developed
(some doubly-terminated) Quartz crystals, accompanied by a single colorless
2-cm Topaz (Al2SiO4(F,OH)2),
and about one dozen small green octahedral Fluorites (CaF2),
half of which are inside the Quartz crystals. Regardless of whether
they are inside the Quartz or not, all of the Fluorites fluoresce bright
canary YELLOW under SWUV! The only locations for
bright yellow fluorescence by Fluorites that
I have found in a table from the Fluorescent Mineral Society are Norway
and New Mexico, and I have never before seen it. (This is
not at all the same as the cream yellow that comes from petroleum inclusions
- see the previous Gallery for one of those.) Besides containing
Fluorites, the Quartz also has inclusions of Phlogopite and dark-brown
needles of some unknown. This is a one-of-a-kind piece for a collector
of rare fluorescents or rare Chinese minerals.
WOL10-1
Wollastonite with Barite on Calcite $145 SOLD Franklin, Franklin Mining District, Sussex Co., New Jersey 12 cm x 8 cm x 7 cm
WOL10-2 Wollastonite with Barite on Calcite $85 SOLD Franklin, Franklin Mining District, Sussex Co., New Jersey 6.2 cm x 6.8 cm x 4.3 cm
RU10-1 Corundum variety Ruby, on Marble $48 SOLD Jegdalek Ruby Mine, Sorobi District, Kabul Province, Afghanistan 7 x 5.5 x 4 cm; Ruby crystal = 6 mm There
is nothing that glows in LWUV like a Ruby (Al2O3),
and these specimens from Jegdalek are even brighter than most. The
matrix is primarily marble, but there is a seem of powdery white that
fluoresces blue-white and feels like Talc. About half of the Ruby
crystal (an octahedron) shows above the matrix.
RU10-2 Corundum variety Ruby, on Marble $42 Jegdalek Ruby Mine, Sorobi District, Kabul Province, Afghanistan 4.5 x 3 x 2 cm; Ruby crystal = 5 mm There
is nothing that glows in LWUV like a Ruby (Al2O3),
and these specimens from Jegdalek are even brighter than most. The
matrix is primarily marble, but there are a couple small patches of
powdery white that fluoresce blue-white and feel like Talc. About
half of the Ruby crystal (a distorted octahedron) shows above the matrix.
RU10-3 Corundum variety Ruby, on Marble $48 SOLD Jegdalek Ruby Mine, Sorobi District, Kabul Province, Afghanistan 5.5 x 4.5 x 3.2 cm; Ruby crystal = 12 mm There
is nothing that glows in LWUV like a Ruby (Al2O3),
and these specimens from Jegdalek are even brighter than most. The
matrix is primarily marble, but there is a patch of powdery white around
the Ruby that fluoresces blue-white and feels like Talc. This
crystal is contacted, but gives the most fluorescence of the 3 Afghani
specimens, as it is the largest.
RU10-4 Corundum variety Sapphire on Marble $65 SOLD Neelum Valley, Muzaffarabad district, Azad Kashmir, Pakistan 6 x 4.3 x 2.7 cm; Sapphire crystal = 10 mm I'm calling this one Sapphire (Al2O3) because it is distinctly purplish. Nevertheless it glows in LWUV like a Ruby, and this specimen from Neelum Valley has more fluorescence than any of the other Corundums on this page. There are multiple crystals on this specimen; some of the crystals are contacted, but many show classic Corundum forms. There are also some very interesting, unidentified, dark shiny crystals on the back side. They look like Graphite, but I can't scratch it, so ...?
HAU10-1 Haüyne,
Scapolite, Chrome Tremolite, Talc & Lazurite $95 Balmat,
Balmat-Edwards Zinc District, St Lawrence Co., New York This rare piece is a combination of many of the minerals found at the Zinc mines at Balmat, and would make a good companion to the famous Balmat cubic Magnetites (I have a few small inexpensive ones available.) The Haüyne ((Na,Ca)4-8[Al6Si6(O,S)24](SO4,Cl)1-2) fluoresces orange in LWUV; the Scapolite (a series with end members Ca4(Si, Al)12O24(CO3,SO4) and Na4(Al, Si)12O24Cl)) is yellow in LWUV; the Chrome Tremolite ([Ca2][Mg5][(OH)2|Si8O22]) is green in ordinary light and yellow-orange in SWUV; the Talc (Mg3Si4O10(OH)2) is whitish in SWUV; and the Lazurite ((Na,Ca)8[(S,SO4,Cl2)|Al6Si6O24]) does not fluoresce, but is dark blue in ordinary light.
VINO10-2 Vinogradovite
and Aegerine $30 SOLD, Rasvumchorr
Mt, Khibiny Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region,
Russia Pale fibers of Vinogradovite : (Na,Ca,K)4Ti4AlSi6O23(OH)·2H2O are accompanied by green-black Aegerine and some other unidentified minerals. The Vinogradovite is easy to identify because it fluoresces strong yellow in SWUV. The alkaline plutons of the Khibiny Massif produce minerals similar to the alkaline pegmatites of Mont St-Hilaire, so this is a way for Alkali-Nuts to get some cross-training. VINO10-3 Vinogradovite and Aegerine $28 SOLD Rasvumchorr
Mt, Khibiny Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region,
Russia
Pale fibers of Vinogradovite with green-black Aegerine and an unidentified
white, bladed mineral. The Vinogradovite fluoresces strong yellow
in SWUV. VINO10-4 Vinogradovite and Aegerine $30 SOLD Rasvumchorr
Mt, Khibiny Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region,
Russia
Pale fibers of Vinogradovite with green-black Aegerine and an unidentified
white, bladed mineral. The Vinogradovite fluoresces strong yellow
in SWUV.
Jajarkot District, Bheri Zone, Nepal 2.3 x 1.7 x 1.7 cm A nice chunky Dravite with flashes of honey-brown, turns an unlikely mustard-color under SWUV - who would have guessed?
STRON9-2
Strontianite $26
SOLD Faylor-Middle Creek Quarry, Winfield, Union Co., Pennsylvania 4.5 x 4.5 x 1.5 cm Well-separated balls of spiky white Strontianite (SrCO3) on limestone fluoresce and phosphoresce cream-blue under SWUV.
HY9-14
Hyalite $42 SOLD Sierra
de la Candelaria, San Pedro Corralitos 12 x 11 x 9 cm A
large geode half with many flower-like sprays and masses of bubbles
of Hyalite Opal (SiO2·nH2O) that fluoresce
bright green in SWUV.
HY9-10
Hyalite $14 SOLD
Sierra de la Candelaria,
San Pedro Corralitos 7.0 x 7.5 x 4 cm A pretty geode section with a flower-like spray of water-clear Hyalite Opal (SiO2·nH2O) that fluoresces green in SWUV.
Darre Pech, Nangarhar Province, Afghanistan 9.7 x 4.2 x 1 cm A good-sized Kunzite that fluoresces magnificently. Good terminations on three edges with a partially cloven bottom edge.
