Help needed with Cads of heart ring

[ElizabethR]

I just got the cads of two rings. I'm not sure I understand the top-width part. Does that mean the width of the halo surrounding the wire-like bezel? Both would be 2.60mm.
Sorry don't know why the first picture doubled.

My question has been answered. It's the width at the top of rhe shank.
