A New Game

I've been playing a new game online & since I'm "hosting" this months edition of it, I thought I'd share it here with you to see if any of you are up to the challenge.

In the empty space on that table in the picture is placed a "Mystery Item". It cannot be fully concealed if you held it in both hands, but it isn't much larger than that.

Please feel free to guess the item by using the comments feature below. Good Luck!
