Antique gold, coral, and diamond ring

Antique gold ring (a mixture of 9k and 12k gold) originally purchased online from a UK-based seller, I have included photos of the original listing which include additional information about the ring’s condition and background. She thought it dated to around 1870. Coral cabochons surround a small rose-cut diamond in the shape of a flower, with lovely scrolled shoulders. British hallmarks visible inside the band. Since this is a true antique it’s a bit delicate and might not stand up to heavy wear and tear. Signs of wear in keeping with antique condition. It’s currently a size 7.
