I like the white background. How is the shadow done?
Use a separator to create two gem pathways and on one of them [scaleXYZ] to 0 in the y dimenson and expand slightly in the x and z, and then color everything black. I have an abstraction to do this automatically but it's a bit fiddly and doesn't always work 100% correctly. You can see that the shadows aren't "real" if you do certain things, like their size and position should be dependent on the height of the geom, but they aren't. With a vertex shader it would probably be much easier to do this still of shadow and make it look good (e.g. set the y component of verticies to 0 and then stretch the x and z componentents depending on the original y value).
Best,
Chris.
