An aesthetic toenail cluster of sharp, glassy, zoned, honey-yellow, pseudo-hexagonal sturmanite crystals from the famous N'Chwaning II Mine of South Africa. The prisms are on a thin complimentary crust of manganite and the contacting of one crystal in on the back, out of sight. Excellent material from the Charlie Key Collection.
