Kalshadarlis's Necklace Reference

This is an iPad photo of what Kalis's necklace looks like. It is mainly for people who are drawing Kalis for me, but I thought I might as well post it. ^^
Yes, I know it looks green: it was drawn on a green paper. If you can't read what I wrote, it points out the golden chain, the bluish purple gem (see this image for the colours), and the claw-like thingies that hold the gem in place (they are attached to the metal part of the necklace that connects the gem onto the chain by a loop). It is a very shiny gem, but I haven't decided whether it glows or not. I believe it just shimmers. The chain is about as big as it's been drawn here or is a little smaller; and it is actually made of round—not squareish—links. I just haven't figured out how to draw chains well yet. ^^

Some other helpful points:
Kalshadarlis's horns (which have two spikes at the bottoms, with the second being slightly smaller than the first) are coloured at a gradient, but the tips are distinctly black and the part attached to her head is distinctly white or very light grey. She has light blue eyes and a white mane, her belly is white, and the the hair that goes from her head to the end of her tail (which is like that of a lion's) is also white.
