Global Royalties Limited review: buying/selling precious stones

Since March 2012, I have purchased several diamonds and emeralds from Global Royalties. I asked Global Royalties to sell what I'm currently holding back in August-September 2013 time frame. This is part of what they do, or so I was told. I was given a few excuses between then and now, the last of which was on August 27, 2014, by Robert Wilson, Director of Sales, having replaced William Brown. He said summer was a slower time, that things pick up after Labor Day, and we should touch back at the beginning of the 4th quarter. I was extremely busy in October and I didn't hear anything from Robert Wilson or Global Royalties. I tried to get them over about a week or 10 day period in the early November 2014 time period, to no avail. The website comes up as under construction, and the phone numbers are not in service.
