Item #10558
Amethyst (scepters and reverse scepters)
Karur District, Tamil Nadu, India

This spectacular ring of sceptered and reverse sceptered amethyst crystals comes from a granite quarry producing road rock in India. Most specimens from this area are quite small, but quite attractive. This specimen measures 10.5 x 10 x 2 cm and is the largest single "pinwheel" I have heard of. It is in remarkable condition, with only one small ding.

All of the crystals originate from a single point in the center. In fact, if you look at the reverse, you can see that the crystals formed in a spiral upward, not just in a plane. And every one is sceptered on the end. I would really like to understand how this formed.

Reminiscent of the amethyst from Irai, Rio Grande do Sul, Brazil, but so much nicer for the symmetry and sceptering.
