Crystal obelisks so very sleek!

I think any obelisk can work in contemporary decor, but there is no doubt that clear crystal looks very modern.

Clear obelisks almost seem like ghosts in the room. They are there, but they don't take up any space. They look mysterious in a darkened room, and add glamour to a coffee table, the entryway, or on top of a book!
