Elegant Blue and Gold Women's Ring

This is a beautiful genuine 10K yellow gold ring with London blue topaz and diamonds. The Gold, topaz and diamonds have all been tested and are genuine. Ring is in very good basically new like condition. I do recommend a proper cleaning and polishing. It hasn't been worn and has been in storage since early 2000. Ring is a size 8 and the markings are 10K and the letters PR or RP (see pics) Weight of the ring is 4.0g. Estimated value from a jeweler is between 550 and 650. Feel free to ask any questions. Thanks
