Here's a jewellery pet peeve I never knew I had: when people mix 14k goldfill and 22-24k vermeil, goldfill and brass, or sterling silver and pewter components. On the same piece.

Sure, it's nice when you mix metals for a contrasting difference, but with these combinations, it's like looking at two different shades of turquoise instead of looking at turquoise and blue. I feel really uncomfortable when things are almost the same but not quite. What's more, these different metals are going to oxidise at different rates and change the look of your jewellery.

Is it so hard to find a matching component?? I just don't get it.
