Beryl var. Aquamarine - $5500
Shigar Valley, Baltistan, Pakistan
6.7 x 2.9 x 2.0 cm

MMS-230 - Water-clear and pristine, this aquamarine crystal looks like the creation of some master architect. The bevelled edges and complex termination are beautiful, but the real wonder of the piece comes from the twisted look of the crystal. A bit of albite matrix is attached. The piece is undamaged with very minor contacting next to the existing matrix. A true natural sculpture the like of which we have not seen in our 25 years of working with fine minerals.
