I wish I knew. It may already have been done. Even if it hasn't been done, Meg's opinion is as good or better than any GIA report so I am sure our MD already knows the quality.
The slow down in the first parcel sale is a good sign I think. The original timetable was quite rushed as MUS was looking to raise cash to keep things moving. Now that the CR went well our MD has the time to negotiate the best deal, not the quickest, and to use the exceptional stones to build the brand. All good for the long term.
On the subject of branding I can't see Mustang being the brand (mustang does not say to me rubies) - I am predicting something African sounding.
