Well - this isn't exactly a gorgeous thing, but this was me experimenting with a stamp - and then encasing in one shot, trying to trap an air bubble in the shape of the stamp.
I think it might be more interesting if it was stamped into clear or a light transparent, and then encased with the same colour, for a more floaty effect.
Clearly, I was working with not enough oxygen, as witnessed by the red streaks in the turquoise. Although, you could argue that the red streaks tie into the skull and crossed bones pirate theme of the stamp.
I was thinking this was pretty icky, but maybe it's worth another shot.
