I have another beautiful mystic topaz available! This one is called a "twilight" or "Salmon" topaz. These are genuine topazes that have been coated by a vapor disposition process that causes these color changes. This one measures 9x7 mm (2.5 ct) and is primarily coral colored with flashes of green, yellow and blue. In addition to the topaz there is .01 ctw of round, genuine diamonds for accent. The setting is solid 14k yellow gold. The crown of the ring measures 13x12 mm (9/16x1/12). The ring weighs 4.3 grams and is a size 7, easily sizable by your local jeweler.
