This specimen is made up of a deposit of Sturmanite discs that are slightly fatter and much more saturated in colour compared to the March 2005 find. These come from a pocket in Nov 1998, the Sturmanite discs have a good lustre and very nice deeper colour and are deposited onto a thin host matrix which also has a deposit of fine-grained Hematite. The largest crystal reaches up to 7mm. The specimen can be displayed from both the back and the front and overall in great condition. There are a couple of minor contacts around the edges of the specimen.
