Here’s a necklace rendered with blender internal
Please post your C&Cs
Looks to be all procedural based - is it? If so, incredibly skillful use of the internals 
Either way man, beautiful material you have there - I think I’d sell my soul for one =)
Very nice. It’d be interesting to see how you did the internal glow.
Here’s a .blend file with a part of the model and the materials(with packed textures)

If it was hanging, the chain would have more of a V shape to it, but perhaps this is lying flat on a cloth?
Nice lighting
Interesting pendant…is the design significant? Looks kind on Incan or something…
No the shape is just imaginary it is not a symbol or something else
very nice use of precedurals and light, this is fantastic and very skillful work.
4 stars from me!
Nice lighting and textures. Render looks a little jagged, so I’d try doing a higher quality render.

Beautiful render! Thank you for the .blend.
Very nice!
I never would have thought the “Clouds” texture could come in handy like that. Plus the file was a great addition.
