This is a charming antique, art deco period, 18ct gold and platinum blue sapphire and 0.36ct diamond cluster halo ring in a size P, US 7 3/4. The band measures approximately 1.5mm in width, and the head of the ring measures around 12 x 9mm, so is a fairly good size. The main stone measures around 5.5 x 4.5mm, and there are 12 x diamonds, each measuring approximately 2mm (0.03ct each, approx) with a total combined carat weight of approximately 0.36ct. I do not know the colour or clarity of the diamonds, but they are nice and bright and clear. The stones are set into a thin layer of platinum which compliments them beautifully. It is stamped with 18ct as pictured. It is in very good condition considering it's age and it weighs approximately 2.8g. Any questions please ask. Box for display only but alternative supplied.
