Well, the specific color you used won't matter too much as the NES has a 64 color-only palette, so I'd have to use what's closest to any submissions.
As for the graphics, I like the red and green ones. The blue one looks neat, although I don't think I'd call that a jewel... Looks more like a snowflake. The orange square-like one could use some tweaks to the highlights, but that is a shape I'd want. The purple one looks like an hourglass, so that one is a nay. The yellow one is alright, although I think like the orange one it could use a tweak to the highlights.
A good start though.
I attached a file of what the gems from the original Columns looked like. They obviously won't be this detailed on the NES, but it could help.
