Exquisite specimen of Plancheite on specular hematite and quartz. The radial growth of the Plancheite forms lovely blue spheres larger than any I have ever seen - the largest here being a full 1 cm across! The robin's egg of the species. There is even a nice cluster of three smaller spheres tucked away in a vug on the opposite side.
