I used a mold of one of the original stones to cast these replicas. The level of detailing in the Ancient writing is amazing considering how few close-ups were shown on screen.
These were painted so that the color would reflect light. They are very dark normally, but under light they are a dark purple.
Will have photos soon of the custom matte board displays that I am making, and also some nice display box options. In the mean time they are available for order at sg1props.com/store/stone.
