2PC-0HUManganite Mn3+O(OH) , Rhodochrosite MnCO3
Dimensions: 4.2 cm x 2.2 cm x 1.5 cm
A rich specimen with dark black lustrous short crystals of manganite on both sides, resembling specularite. However on one side there are small lustrous crystals of pink rhodochrosite. Crystal Vine specimen.
538-494Chalcoalumite CuAl4(SO4)(OH)12·3H2O , Ajoite ? (K,Na)Cu7AlSi9O24(OH)6·3H2O , Native Copper Cu , Cuprite Cu2O , Brochantite Cu4(SO4)(OH)6
Dimensions: 2 cm x 1.5 cm x 1.1 cm
A rich and unusual mix of minerals on such a small specimen. We have small spherical druses of the rare sulfate chalcoalumite, rare silicate ajoite [not or wrongly analysed, could be a cyanotrichite-group mineral] along with brochantite on native copper and cuprite. Crystal Vine specimen, Sara Giller photograph.
EHV-0PUCalcite (Var: Manganese-bearing Calcite) (Ca,Mn)CO3
7 x 4 x 4.5
A fabulous new find from this classic locality, this manganocalcite is formed of a mass of light pink sprays. The pink calcite seems to have attached itself to white string like crystals which could possibly be quartz or calcite. This is an amazing looking specimen, which fluoresces under UV light too.

DV9-2H7Feitknechtite Mn3+O(OH)
Dimensions: 7.5 cm x 4.2 cm x 3 cm
A rare oxide, Mn3+O(OH). Shows as the red/brown xln throughout with braunite and hausmannite. 7.5 x 4.2 x 3 cm Sara Giller photograph, Crystal Vine specimen.
Y55-QWRFluorellestadite Ca5(SiO4)1.5(SO4)1.5F
Dimensions: 5.7 cm x 4 cm x 2.4 cm
A very rare silicate Ca5(SiO4,PO4,SO4)3(F,OH,Cl) from the apatite group. Usually blue in colour. 5.7 x 4 x 2.4 cm. ara Giller photograph, Crystal Vine specimen.
HF2-FAWStishovite SiO2
Dimensions: 6.3 cm x 4.5 cm x 4.4 cm
This is a very rare oxide SiO2 and is polymorphous usually with coesite, cristobalite, quartz and trdymite. From the tetragonal crystal system and is usually colourless or transparent. 6.3 x 4.5 x 4.4 cm. Sara Giller photograph, Crystal Vine specimen.
HP0-6DACassiterite SnO2
Dimensions: 4.5 cm x 4.3 cm x 2.6 cm
Bright dark brown fairly lustrous small cassiterite crystals on a mottled matrix with possibly some bluish apatite. The largest cassiterite measures 4mm long. Unusual locality. Sara Giller photograph, Crystal Vine specimen.
TAX-J33Pyrolusite Mn4+O2
Dimensions: 4 cm x 3.3 cm x 2.5 cm
4 x 3.3 x 2.5 cm
Pyrolusite specimen which shows scale formations of metallic half discs in an open vugh measuring up to 3mm across.
