I’m looking to get an 8-10mm Hawaiian heirloom bangle in the near future. I’m really struggling with 14k vs 18k yellow gold. My main concern is that 18k will be too delicate and warp/scratch with daily wear. Anyone have thoughts? I know things like the Cartier love are 18k and they seem to do fine with daily wear. I’m just hoping this is true of a larger and somewhat thinner piece (1.5mm thickness).
