I did simple crown, take her if You want ;)
I will use it at http://growlution.net once I finish my buffer :) Will update by end of august.
However, I did have to do some major cleaning up for edge flow and proper rendering. It's a very well-designed model so please understand. I do not want to discourage you but this is what I had to do. I had to delete the pearls and replace them with uv. You want clean crisp lines no triangles if possible and don't be afraid to separate the pearls from the points as you did with the ruby. You want to be able to alt-click and cave a edge loop all the way around the section, including the edges of the base. In the end, I just used yours as a 3d reference and duplicated it because I need to highlight the detail in freestyle by adding lines and I cannot do that if the molded bumps do not have a solid edge loop. I'll upload my version and give you full credit for the inspiration.
Thanks for your comments, I appreciate it.
