This is a pretty specimen, three central fluorite cubes are surrounded by a myriad of smaller lighter green cubes. Some of the crystals feature prominent phantoms, and colour zoning is evident in most. The crystals are sharp with good lustre, and are transluscent to transparent. Strongly fluorescent under UV, as shown in the last photo. In very good condition for the find, with some chipping. Stands perfectly for display as photographed – a nice cabinet piece.

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.
