Clark & Coombs 10k gold filled ring jade stone green center size 9 <C&C>

It's stamped 10k gold filled. The <C&C> stamp is the brand Clark & Coombs. Outer part is excellent condition. Not sure if the stone is actual jade or some other green colored stone. No size listed, but it fits my index finger, and I wear a size 9 on it. Listing it in women's, but I think this ring is unisex IMO
