Specimen # 102317
Mineral: Fluorite
Location: Fluorite, Mandrosonoro, Ambatofinandrahana, Amoron'i Mania, Madagascar
Size: 6.3 x 5.8 x 4.5 cm


Detailed Description

This large cabinet specimen is features colour-zoned fluorite cubes with prominent phantoms. The crystals are sharp with good lustre.  Strongly fluorescent under UV, as shown in the last photo. In excellent condition, very minor chipping. There are several ways to orient this piece for display. I would personally choose the one in the first photo (it lies down nicely like this, so would be good on a mid- or lower-level display case shelf, perhaps supported tilted up a little). In this orientation, the colour zoning and phantoms just jump right out – they look spectacular.

If shipped outside North America, there will be a small additional amount for shipping on this one.

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.
