I have managed to source some of these beautiful rare Garnets direct from the mine in Kunar Province in Afghanistan . If you can not see what you are looking for please message me as I have a few different shapes and sizes available.
11.3cts Oval cabochon with a slight dome and a flat back. 12.7mm x 21.5mm x 4.3mm at the largest points.
This is a lovely deeper, natural green with a slight translucent tone with deeper green markings in the centre.
