This wonderful cross pendant is marked 750 at the top but is hard to read. I tested it with nitric acid and a "kee" tester to be solid 18k white gold and it weighs 8.0 grams. With the bale it measures 1 1/2" x 1" . The cross holds 61 red round natural rubies with an approx total weight of 1.83 cts. Set in the center on the cross are a total of 13 round brilliant cut natural diamonds . They are VS quality and have an approx total weight of .32 cts. The bale at the top can accommodate up to a 5 mm chain. This piece is in excellent condition.
