Thanks Civ; I am always fascinated by tales of megalithic-sized semi-precious stones. A few years ago I visited a turquoise deposit and the engineer told me they frequently remove 'refrigerator and pick-up sized chunks'. They mined one single piece that was made into a boardroom meeting table. Nothing like that for my visit, but they did let me fill a couple sample bags, all that would fit in my carry-on. :)
I wonder how much a turquoise refrigerator would weigh? ;') Cool color scheme, that would be.
