The custom made ring is marked 14k and is solid yellow gold. It weighs 4.5 grams . Set at the top is a golden natural precious topaz. It measures 13.5 x 5.7 x 3.9 mm which makes it approx 2.00 cts. Set above the topaz is a blue stone that I have not been able to identify . The ring wears to a size 6.5 and can be resized by your local jeweler.
