Description

The crystal shows exceptional luster, it is water-clear and shows an elongated aesthetic habit. On one side is partly covered with intense red-brown siderite, which gives a spectacular contrast to the piece. Not only a stunning alpine crystal, also a rarity - material from the locality is very hard to obtain! No significant damages to report.
