Steph, it's a 3/4 marble.
And, you can tell by the glass like Kevin mentioned.
And, I don't think there were that many flames made.
And, I like marbles because they're pretty and kewl and fun and I don't care who made it or when they made it, I just like the 'world' it takes me to (it's like calgon take me away...lol)...and...well, they're just awesome!
