DESIGN PROCESS: Silver or Black Chain

Here's a sneak preview of some necklaces I've been working on. These two are for me, but I have made many others in similar styles to sell. Before I start adding the metal bits to finish them, I need help deciding which one looks better...the silver or the black. Leave a comment below letting me know your choice.

If you are curious as to what the designs are, the left is a sun and the right is a rainbow galaxy. These are my fantasy versions, but who knows, they could really exist like this somewhere in the vast space we float in.
