AQUAMARINE WITH ILMENITE INCLUSIONS
Leopard Aquamarine is a very nice gemstone from Minas Gerais, Brazil.
It is a variety of beryl deeply included by oriented black ilmenite inclusions.
Ilmenite crystals are responsible for a nice Schiller effect, similar to
that of sunstone. The Schiller is associated to a nice rainbow that rise
from oriented microfractures induced in the beryl by the ilmenite crystals.
This effect can be seen just at some angles. The material can be cut in
a variety of different gemstones that take different names. Leopard Aquamarine
refers to stones with evident blue color and black dots, Sunstone Beryl
refers to stones with strong Schiller, Black Beryl refers to stones very
deeply included. Some stones also show cat's eye effect.
