This beautiful ring the has a natural 1/2 carat deep blue sapphire as the main stone with a four small natural diamonds as the secondary stone, with one being on each corner of the face of the ring. When I first bought the ring I thought the stone was onyx as it was so dark but when I held it up to the light I noticed it was actually a deep blue that is when I realized it was a dark blue sapphire and after having it checked.it was!
