This is a piece of Aquamarine rough that is suitable for cutting. It has a nice open C axis which means the stone will be nice and bright when cut.
This piece has many fractures on the edges that penetrate into the stone. It will take some time to study this stone and perhaps cut it into a few small stones to get the best yield.
There is a crack half way down lengthwise down the stone approaching towards the centre of the width. It is a few millemetres deep.
