The pair of antique earrings do not have a metal mark but were tested with nitric acid and a "kee" tester to be 10k solid rose gold. Together they weigh 4.4 grams and measure 1/2" x 1/2" . The earrings are horseshoe in shape and each holds 9 round blue persian natural turquoise ranging from 2.5 mm to 3.5 mm. They are for pierced ears and come with large earring backs. They could use a light cleaning and are in good shape.
