Description from the seller
Approximate place of discovery
23°17' North
11°14' West
Despite its size, the translucency is good, which is what makes this ruby distinctive.
The color is blood red....
All of this makes this ruby a truly exceptional piece
This large ruby crystal (corundum) comes from Mauritania, (Tiris Zemmour region) about 100 km from the town of Zouerate.
I found this ruby during research and reconnaissance in the Mauritanian desert
I am offering it as I found it; I have not subjected it to any heat or chemical treatment, just cleaned with soapy water.
All photos were taken in natural daylight.
For some of them I placed the ruby on the lit flashlight of my mobile phone
To show the strong fluorescence reaction characteristic of corundums (ruby and sapphire) under ultraviolet lighting, I additionally illuminated this ruby with a small lamp that emits ultraviolet light.
I photographed this gem as honestly and as precisely as possible using daylight.
Please note that differences in screen settings and ambient lighting can lead to variations in perceived color, saturation, and tint.
The ruby you will receive is, of course, the one in the photos.
I ship quickly, securely, and discreetly in a sturdy C5-size envelope (162mm x 229mm) via La Poste, France, by registered mail.
Shipped with a tracking and traceability code.
