RM2716 Davidite-(La)
Radium Hill mine, Olary, South Australia, AustraliaSpecimen formed by several interpenetrating davidite-(La) crystals. We can observe various curved, shiny facets of this rare species, from the crichtonite group, and of a complex formula with an unique combination of elements: La(Y,U)Fe2(Ti,Fe,Cr,V)18(O,OH,F)38.
It belongs from the type locality for the species: Radium Hill. To confirm the species we have carried out SEM-EDS analysis with results consistent with expectated. It is not easy to find specimens of the type locality and less with facets.

RM2600 Twinned gypsum with inclusions
Lake Gilles Gypsum Deposit, Corunna Station, Iron Knob, Eyre Peninsula, South Australia, AustraliaGroup of twinned "hourglass" and "fishtail" gypsum crystals. Specimen with very good transparency, colorless and doubly terminated. It comes from the famous Lake Gilles in South Australia. The crystal is floating and its transparency allows us to see the inclusions of arrow-shaped clay particles. Lake Gilles produces some of the most unusual gypsum crystal shapes in the world.
Size: 6.2 x 3 x 2.2 cm.
Found in ±1984

RM2580 Scholzita and Chalcophanite
Reaphook Hill, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia, AustraliaScholzite is a rare calcium zinc phosphate, with a type locality in Germany, although the richest and most aesthetic specimens have been found in this Australian mine. This sample shows us, on both sides, numerous aggregates of prismatic crystals, almost acicular, transparent and brilliant. They are accompanied by globular aggregates of chalcophanite (analyzed by SEM-EDS).
Size: 6.6 x 6 x 5 cm.
Main crystal: 1 cm.
Found in ±1985.
Analyzed specimen with report

RM2579 Scholzite and chalcophanite
Reaphook Hill, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia, AustraliaScholzite is a rare calcium zinc phosphate, with a type locality in Germany, although the richest and most aesthetic specimens have been found in this Australian mine. This sample shows us, on both sides, numerous aggregates of prismatic crystals, almost acicular, transparent and brilliant. They are accompanied by globular aggregates of chalcophanite (analyzed by SEM-EDS).
Size: 8.8 x 5.8 x 3.8 cm.
Main crystal: 1 cm.

RM1623 Scholzite
Reaphook Hill, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia, AustraliaVery rich scholzite specimen, an unusual phosphate of Ca and Zn, with elongated prismatic crystals, transparence and brilliance. It comes from a classic Australian locality for the species as is the Martins Well area, about 40 miles SE as such indicates this old label. A zinc and phosphorus-rich deposit in dispirited breccia. It is as mined for a few years for mineral specimens (mostly scholzite).
Size: 6.4 x 4.4 x 3.2 cm.
Main crystal: 10 x 1 mm.

RM1367 Ilmenite with epidote
Arkaroola Bore, North Flinders Ranges, South Australia, AustraliaThis specimen is really interesting not only for the quality of the crystal but the locality it comes from. Few specimens are represented in collections. This sample shows a brilliant metallic luster and sharp faces and edges. Located in a gully, this locality consists of outcropping hydrothermally-altered and weathered Wooltana volcanics containing veins and pockets of zeolites, calcite and crystallised ilmenite.
Size: 5.3 x 4.7 x 2.8 cm.
Main crystal: 27 x 20 x 8 mm.
