So, 30 years ago a 19 year old Diana picked a large blue sapphire ring out of a tray because she thought it was pretty. Does it really matter whether it is now considered top quality or not? The Queen's diamond (3 carat) came from a busted up tiara, and she's fine with it. There are PS'ers with more far more expensive rings. I just find all this dispute kind of funny. Sure there are connoisseurs here on this board, but 30 years ago this was not an issue. I'm sure it was top quality something for the time period. Tastes also change over time. If I had a choice, I would pick a Kashmir, but at 19 I probably wouldn't have cared too much. Surely it is a stunning piece regardless of whether it's too dark for an individual's taste today.
