your stones look very similar to some 'Crow Springs ( Tonaopah Nv.area)… the paleness of the green… is what makes me say that…?..
There is a mine called De’molly ( spelling?)… and it actually wasn’t a turquoise, but a vericite…but was sold as Turquoise and I suppose still is… ( one mineral difference)
Love those big chunky peaces…
