Although I don’t actively collect buttons and buckles any more, I still buy them when I come across examples that I really like (assuming that the price is right, of course). A while back, I found half a glass belt buckle. It was this fantastic shade of zingy lemon yellow, with contrasting silver-coated bars. What on earth do you do with half a Deco belt buckle though?

It actually makes a rather nice pairing with a ring of a similar vintage:

The band and setting are made from brass and the ring would have been the cheapest of the cheap when bought new. But it still looks great.
