I’ve tested it over and over and the highest gold testing acid I have is 22k. It doesn’t disappear on that test or any other under it…. Could be 24k gold I’m not sure? Sapphire and seed pearls with trombone clasp dating it to 1890s. Country of manufacturer unknown. Similar 22k gold jewelry shown in last pics what they sell for for an idea on value. Worth anywhere from $900-$6800. I would bet it’s somewhere in the $1500-$3000 value.
