Item Description
A colorful and impressive large combination specimen from the famous N"Chwaning Mines. Lustrous, translucent, lemon-yellow, hexagonal, ettringite crystals are aesthetically clustered on the hefty ore matrix plate covered with creamy bultfonteinite, a rare silicate. The doubly terminated ettringite on the left is 3.8 cm and the larger crystal on the right is 4.7cm. This crystal is contacted on the front, but has no damage, per se. Most excellent large material from the Charlie Key dealer stock. Fairly valued at $1750-2000. 6.6 pounds or 3 kilos.
