The design is a small (3" square) sunk dish with some chasing on the inside. Originally the design was to have been repoussed but I felt that it would have looked odd, the raised design inside a small sunk area. The final decision was to just chase the design and it looks good.
What it took:
1/2 hour for design
1/2 hour for inserting into pitch pot and doing the initial lining
3/4 hour for forming/annealing, repeat a few times
3 hours put back in pitch pot and the chasing design
1/2 hour to anneal and get back into shape
1 hour to file, sand and shape corners
1 hour initial polishing
1 hour to make and attach ring base on bottom
2 hours of hand polishing.
Total: 10.25 hours and a good feeling of accomplishment
