Vintage ‘J’ Gold Initial monogram Letter "J" Charm Pendant preppy coquette girl

Gold letter monogram charm 1"high x 1/2"wide. Great on a chain. I added a video trying to make the charm stick to a magnet, & it did not stick which is one indication of it being real gold. Also, I tried the vinegar test on it to see if it tarnished on an inconspicuous spot, & it did not change the color at all. I believe this is real gold because of its highly detailed workmanship, but there is no mark on the back. Weight= .95g. About 30 years old or more.
