AI-assisted summary
Description from the seller
Approximate location of discovery
23°17' North
11°14' West
Huge 300-gram ruby crystal
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 thermal 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.
In order to show the strong fluorescence characteristic of corundums (ruby and sapphire) under ultraviolet light, I additionally illuminated this ruby with a small lamp that emits ultraviolet light.
I photographed this gem as honestly and precisely as possible using daylight.
Please note that differences in screen settings and ambient lighting can lead to variations in the perceived color, saturation, and tone.
The ruby you will receive is, of course, the one shown in the photos.
I arrange fast, secure, discreet shipping in a tamper-evident C5 envelope (162mm x 229mm) by French La Poste registered mail.
Shipped with a tracking and traceability code.
