Specimen # 102314
Mineral: Fluorite
Location: Fluorite, Mandrosonoro, Ambatofinandrahana, Amoron'i Mania, Madagascar
Size: 9.2 x 7.3 x 4.7 cm


Detailed Description

A beautiful specimen, with green fluorite crystals contrasting against light matrix. The fluorite crystals are sharp, translucent to transparent, and colour-zoned with good lustre.  Strongly fluorescent under UV, as shown in the last photo. In very good condition, with one chip and some very minor rubs. In the one photo, I’ve specifically photographed the one chip to highlight it, but you don’t see it unless it is angled to catch the light (it reflects a spotlight located overhead to the right of the specimen, but it is not visible with a spot overhead, or to the left of the piece). This is one of the best display specimens from the lot – displayed supported as photographed, it stands out from across the room with great colour and contrast.

About These Madagascar Fluorites

Discovered in 2017, this Madagascar green fluorite is from Mandrosonoro, Ambatofinandrahana, Amoron’i Mania. The green varies in darkness from specimen to specimen, and the hue is reminiscent of the specimens produced at the Rogerley Mine (Frosterley, Durham, England).

The apparent colour of these fluorite specimens varies depending upon light source – these photos are adjusted to basic daylight, shade (same as all specimen photos on the website), and this is the lighting that brings out their colour the best. However, in actual daylight, these fluorites exhibit varying degrees of fluorescence, from faint to obvious blue (not as strongly as with Rogerley fluorites). Under UV lighting, they fluoresce bright blue-purple.

The Mandrosonoro fluorites are collected by local inhabitants and the quality of the first pieces I saw (in 2018) was very poor. On the whole, the quality of almost all pieces available to date has remained poor with lots of damage – the specimens in this update are of exceptional quality for the find.
