It’s 18ct gold, with platinum details, made by S.H. & Co, and it has a patent number. The platinum is usually the setting or decoration, not the whole band.

75% pure gold & platinum by: Yvonne
Maharba,
Thanks for reaching out, I am so glad you found us!
Let's work this out together -
s.h & co. is the maker or retailer’s mark. Likely S.H. & Co. 18 ct gold. That’s 75% pure gold. "plat" means Platinum. Usually this means platinum accents, trim, or mounts. Not the whole piece unless it also says 950 or 900 Pt.
The number "32" could be a size, batch, or even an internal model number. "pat 202580" refers to the Patent number. British patents from that era often look like this.
