Discovered in November 2018 within the Southern Flats. This pocket is characterised by 1 cm + cubic crystals of gemmy, mossy emerald-green fluorite. Crystals which are not gemmy are often shades of moss-green with cream to pale creamy-green crazed centres. When crazed, the faces are typically crazed also, but with gemmy corners reminiscent of the Green Hill pocket (2017). Fluorite is present as both single and twinned crystals and the larger crystals exhibit magnificent deep mauve-blue daylight fluorescence. The gemmy cubes typically measure from 0.7 to 1.4 cm and are occasionally distorted with one of the three crystallographic axes longer (i.e. a1=a2<a3).
The Fluorite is often coated with creamy-white Calcite either as undulating botryoidal coatings or delicate platy rosettes to 4 mm across. The largest fluorite is a 2.6 x 2.0 x 1.8 cm cube with smaller interpenetrant twins set in a bed of off-white, creamy Calcite in the form of rosettes.
Named for the gem quality green Fluorite discovered in November 2018. For the gem-quality Fluorite single and twin crystals and its month of discovery.
Figure: Fluorite with Calcite. Excellent light emerald-green, semi-transparent interpenetrant twinned crystals contrasting beautifully against drusy mounds of snow-white Calcite. In this pocket the larger Fluorite crystals are naturally not with Calcite whereas the smaller crystals tend to be completely obscured. November Gem pocket, 9.3 x 7.7 x 3.3 cm.
Figure: Fluorite with Calcite. Gemmy emerald green crystals as interpenetrant twins surrounded with a thin veneer of Calcite coating smaller Fluorite crystals. November Gem pocket, 7.9 x 6.7 x 6.5 cm.
Figure: Fluorite with Calcite. Gemmy emerald-green Fluorite crystals heavily coated in drusy snow-white microcrystalline Calcite. November Gem pocket, 10.1 x 9.0 x 3.7 cm.
Figure: Fluorite with Calcite. A stunning cabinet specimen of smaller cubic Fluorite crystals coted in drusy snow-white Calcite with larger twinned Fluorite crystals remaining uncoated. Although the larger, interpenetrant twins do not appear to be epigenetic (post) with the Calcite, they are often seen in Diana Maria mine to be left uncoated by the Calcite phase, save for the lower edges of where the crystals are attached to the matrix or adjacent Fluorite crystals. Such specimens have not been treated in any way to remove the Calcite from the bigger Fluorites and are totally natural. The Fluorite forms as rich emerald-green crystals with sharp edges, mirror-like faces and display good blue-lilac daylight fluorescence. November Gem pocket, 11.1 x 10.9 x 4.7 cm.
Figure: Fluorite with Calcite. Single cubic Fluorite crystals cover an altered limestone matrix, between which pinkish-creamy tan platy Calcite crystals nestle. Standing proud of the specimen is a gemmy, deep emerald-green twin Fluorite. The smaller Fluorites have cloudy and frosted milky-green centres with some transparent edges and part-faces. November Gem pocket, 10.2 x 6.5 x 4.4 cm.
Figure: Fluorite with Calcite. Detail of interpenetrant Fluorite twin showing the clarity of the crystals and their intense and beautiful colour. The horizontal crystal measures 2.2 cm on edge. November Gem pocket, FoV 3.2 cm.
Figure: Fluorite with Calcite. Gemmy deep emerald-green crystals of Fluorite with razor-sharp edges and highly reflective faces surrounded with snow-white micro-botryoidal Calcite. The Fluorite crystal faces either exhibit concentric growth patterns or mirror-bright faces that enhance the transparency of individual crystals. November Gem pocket, 10.3 x 7.2 x 4.3 cm
Figure: Fluorite with Calcite. A very fine large cabinet specimen of Fluorite coated by a thick botryoidal layer of snow-white Calcite and large gemmy single and twinned Fluorite crystals in two focused clusters. The Fluorite is extremely fluorescent in UV and daylight with the crystals here seen to be emitting a rich blackberry-purple. November Gem pocket, 22.0 x 10.9 x 4.8 cm
Figure: Fluorite: A small cabinet specimen of intergrown sea-green Fluorite crystals, some gemmy and some with frosted centres, crowned with a magnificent deep emerald-green gemmy interpenetrant twin. November Gem pocket, 7.0 x 4.5 x 3.6 cm
Figure: Fluorite with Calcite. Another specimen from this pocket with a thick, drusy coating of snow-white Calcite with individual interpenetrant Fluorite twins punctuating the surface. The Fluorite is gemmy and of a superb rich lime to almost chrome-green with all crystals tinged with purple-blue daylight fluorescence. November Gem pocket, 9.3 x 7.7 x 3.3 cm
Figure: Fluorite with Calcite. Another example of thick, drusy, snow-white Calcite with individual gemmy interpenetrant Fluorite twins. The Fluorite’s colour is stunning deep leaf-green. November Gem pocket, 13.0 x 8.4 x 5.7 cm
