Tourmaline var. Indicolite from Coronel Murta Mine, Brazil

Size: 8.1 x 14.1 x 6.3cm 

Weight: 822g

Here is a large, blue Indicolite Tourmaline from Brazil that has a really unusual termination shape. The tourmaline crystal is a dark blue and very thick, so light does not penetrate the main body.  However, the outer layer is transparent enough that the edges do illuminate when lit from behind, and when lit from the front it does cause it to show the blue color as it appears in these photos. The top has a ~1cm cap that is an even darker blue. The termination is nice and flat, and has a really unusual shape as you can see in the closeup photos.

The tourmaline was found in November, 2019. 

The lab work was done by Nimeral Minlab in Italy in 2020 where they cleaned the specimen and created the included custom acrylic base.
