"To those who are able to explore their secrets, precious stones relate to story as interesting as that of the huge pyramids erected by the Pharaohs at Memphis, and it would seem that their sublime internal spheres might be called, The Fingerprints of God" and also he called them "The usurpers from the factory".

Edward J. Gübelin Inclusions as a Means of Gemstone Identification, 1953.

I think the best way I have to show my customers that my stones are natural is by showing them their interior, which is unique and beautiful. The scale of microphotography can be up to X50.

The Spinel is the latest stone to become part of the list of birthstones. In 2016, the American Gem Trade Association included the Spinel as the birthstone of August.

In antiquity, Spinels have been owned by kings, princes and emperors; have served to fund battles, people have been killed for them, and they have been used as war booty.

As a result of all these fabulous stories, Spinels have adorned the most beautiful crowns that can be found today in the best museums around the world, although under another name: Ruby (an example is the Black Prince's Ruby, which is actually a red Spinel).

In recent years the gray spinel are being used for engagement rings, the mount being made with a dark spinel, surrounded by a halo of diamonds.

We took several photos:
We take photos with daylight (no lightbox and no extra lighting at all).
And we take photos and videos on mirror in a light box with extra lighting (this kind of photos clearly show the quality of the cut and the clarity of the gem).
