This was a quick sketch I did on Photoshop. It was really late at night. I shouldn't have drank coffee this night (It was quite a treat ^.^). I remember having a dream about this necklace and I later drew it in school one day. I'll try my best to describe this.
Everything you see with holes is like a shiny stainless steel metal. The spikes have like a shiny gold metal look, and the centrepiece or the gem on this necklace is an emerald that is somehow etched in the inside that makes it look, what reminds me of the Ballista's sniper scope while not in ADS from Black Ops 2. The necklace chain looks kinda like Raku Ichijo's pendant chain from the anime "NiseKoi" except that for every three or four chain links there's a large chain link.
Well I guess that's it. I'm recolouring it later, but for now I'm going to sleep (-.-) Zzz
