Description: A specimen consisting of a prehnite ball (± 15 x 15 mm) sitting on a matrix of clear quartz crystals which, in turn, sit on a thin matrix of basalt rock. On closer examination, it looks like two balls of prehnite that had fused together to form one.
Apart from limited damage to the edges of the specimen, there are only a few extremely minute nicks (hardly visible to the naked eye) to a few of the lesser quartz crystals.
