I am so happy with the way these came out, even better than I hoped and definitely better than I expected. (They're only two and a half inches square!) Before I started the amethyst prints I had completed a run of Tibetan clear quartz, but now seeing the quality of the amethyst I'm going to re-carve and print them.
Each print in this series (a third stone is coming, tangerine quartz!) will be printed with two blocks, one for the shape and one for the outline. I've already carved down the outlines on the Tibetan quartz so the line weight is thinner and I'll reprint it in black, the shape will stay white but maybe with a little pop of yellow somewhere. Lining up the registration on the amethyst prints was fairly easy because I made sure the carved images on both of the blocks were positioned identically, unfortunately I didn't make sure of this on the Tibetan quartz blocks and the images are positioned at slightly different angles making proper registration much more difficult. Hopefully I can find a way to compensate for this with out having to carve one of the blocks again. I've posted this image before, but here are some of the drawings that started these portraits.
