Well gem quality rubies currently sell between $300 and $700 ct according to GEM.

Unless you think high quality rubies are worth less than lower quality stones then by definition higher quality rubies equals higher value. Of course the total return per ton may be lower, but the quality of what is acquired should be higher and hence sell for more.

While not as good as an actual announcement of the quality mix, it is at least a hopeful sign that MUS should be finding good rubies. It would be better if we didn’t have to speculate about this.
