About Berilo
Beryl is a beryllium-aluminium cyclosilicate. The aquamarine variety owes its blue colour to traces of iron.
About the locality
We don't see many aquamarines from the pegmatites of Myanmar (Burma), Mogok is not as known for aquamarines, as it is for ruby and spinel and other fancier gem crystals. However... from time to time great gemmy pieces like this one appear among those others.
