These two are made out of a transparent blue resin that are similar in appearance to sea glass. I painted them with a super thin layer of metallic paint that appears gold at regular light conditions but if you hold them up to a bright light the entire die glows blue like ice. It's a pretty cool effect. The sides of the dice are the coils of a snake and the 1 side is the head chasing the tail. Dicenarok

Available in raw resin $10 and painted $20 (last picture is an example of a random unpainted dice)

All my dice are made from solid 3d printed resin. The painted versions are sprayed with 3 layers of clear coat so they are usable but I would suggest rolling them on a soft surface to avoid chipping or wear and tear on the paint job.
