Description

Val Giuv is famous for it's excellent smoky quartz. But sometimes very unusual crystals were discovered, just like this naturally etched smoky quartz with 7,5 cm in diameter. The etching process was so intensive, the structure of this one is almost gone. But every face you see is natural and undamaged, what an interesting shape. And even now you can still see it's quality when you give it a little backlight - superb color and clearity
