No supports or brim needed.
I reduced the gem in slicer to fit. 97% was perfect after painting both pieces.
This was a rushed project for a last minute Halloween costume and could certainly be improved. I designed it to resemble the in-game icon rather than how it may look in reality.
The photoed print was spray painted. I think it could look great in Yellow Gold and Gloss Purple filament (or just a decent paint job).
Thank you for your attention.
