With the up-coming re-release of the original Spyro series I decided it would be cool to have some of the Gem Stones as 3D printable decorations. I may draw up the rest of them if this one prints out alright. I haven't done a huge amount of research so this is just based on the first few google image results and what my memory of the original game tells me. Feel free to modify or scale to your liking. If you print this, please post your results as I'm keen to see them!
