^ It's graphite calfskin from the batch of Italian leather that they had at one point. It's a pretty interesting colour; looks black under natural light, with purple/grey undertones under white lighting or brown undertones under yellow lighting.
A word of advice: I owned an Intarsia in a slightly thinner lambskin and although the leather was really great, I didn't like the floppiness of the collar (it was hard to maintain its shape), so it's probably better to look for one in a thicker material. Also, size up - the size small I had was from FW10 (Gleam) and it was basically skin tight on me. I think recent season Rick fits even smaller
