Description

Two aquamarine crystals between bright shining feldspar crystals. The aquamarines show a fantastic shine all around with an intense blue color. This creates a very good contrast in color to the bright feldspar. The termination of the aquamarines is also brilliant. Additionally, they show a slight skeletonization at the ends. The darker blue zoning in this area is clearly visible on the photos. Both crystals are undamaged; the big crystal is 5.2 cm high and measures 3.5 cm in diameter. An excellent piece of perfect aesthetics!
