This amazing pear shaped stone is a new find from a mine in Africa, and only a limited number of these stones have been found, therefore it is quite valuable as a collector's stone! It will make a gorgeous solitaire in a ring or pendant.

Originating from near the Masasi district of Tanzania's Mtwara region, it measures 7 X 5mm and is a minimum of .75 Ct. The faceting is wonderful and catches the light giving it a scintillating sparkle!

The deep and mysterious color is difficult to describe and even more difficult to photograph, as it changed several times as I was taking pictures, and what I saw with my eyes was not always registered on camera. I had to take over 100 shots to come up with 5 that come close to what it looks like in-person.

In some ways it behaves like a natural Alexandrite. It ranges from a purple to blue and at times in the right light you may even see it turn greenish! Sometimes it appears almost black.

It is definitely dichroic, as you can see flashes of blue and violet purple in it at the same time when viewing it from various perspectives!

The supplier I got it from reports that their gemologists were really blown away when looking at the material, that until very recently no blue Garnets were known, and certainly no blue color-change garnets! In some respects this limited stock they aquired defies what had been well-accepted gemological principles.

The material is so new that its make-up is not yet fully understood.

I was lucky enough to be at the right place at the right time to get some of this beautiful stuff!
