Photographing Glass

My wife is an amazing glass artist, and has decided to build a portfolio. This is one of her smaller pieces.

I've been tasked with photographing the glass, and I gladly accept the challenge. I chose not to use a completely enclosed cube, opting instead for indirect lighting (to prevent glare) and lighting underneath to illuminate the glass. This particular bowl was shot on a plain white background, but that look just didn't do it for me. After changing the background to (what I think is) a "more sophisticated" look, something still doesn't feel right to me. I'd greatly appreciate any cc on how you would make this bowl really stand out.
