Vintage Sarah Coventry Jewelry Ring Gold Tone With Amber Marquise Stone Signed

This is a vintage Sarah Coventry signed fashion jewlery ring. It has a ribbed gold-toned band and an amber colored marquise-shaped rhinestone. It’s adjustable as it squeezes in and out and is currently about a 7-7.5 ring size. Ever so slightly mis-shapen due to being adjusted but otherwise nice condition for its age. My educated guess is that the ring is from the 1970s. Thanks for looking
