There have been only two really decent batches of these gorgeous irai calcites over the past couple of years, and we were able to cherry-pick both of them. This is from last years batch, A really significant WHOPPER specimen, with fine silky crystals pointing in all directions. The specimen is a cast of calcite, concave on back, which still retains the impression on the back of the rock surface on which is formed. Big, showy and impressive! 29 x 14 x 4 cm
