Early Birthday Present, Gold Stylus

I always get my presents early, and this year, my husband bought me this 24K gold stylus for metalpoint drawings. The paper is a clay-coated paper from silverpointweb.com. I don’t know if it’s any particular brand. It picks up marks from pretty much everything but appears to erase well, thank goodness.
I’m looking forward to using gold on different surfaces. It looks like a warm gray but has a gold reflection when the light hits it just right.
