Has anyone seen a Chinese ring like this?

Supposedly bone and say “horse” on the back with Chinese zodiac years of the horse from 42’-90’. I assume that would mean they were made pre 42’? Marked “sterling” inside band. This is only photo for now

 

Those horses are recent. They're more likely post-1990 than pre-1950. The cross ring they're with is magnesite, so it was made within the last 20 years.

 

Ah ok, thanks. Just added more photos while you were posting. I saw them in someone’s post somewhere and thought they looked cool so I asked for more photos. I guess they aren’t as interesting as I hoped.

 

From the back they say resin.

 

The back of the horse appears to have capillary lines(bone).

 

Sorta-kinda, but I've seen things with those channels made out of resin before.

 

My first impression is resin too. And I agree, post-1990 rather than pre-'42. Someone in or after 1990 made a list of the horse years since their birth in 1942.
They don't look Chinese made to me, some people in the West also use the Chinese zodiac. To me they are someone's personal mementoes. Cute but very personal.
