Sterling Silver 925 Blue Topaz Aquamarine Halo Pear Oval Gemstone Ring Sz 8 – 5g

The exact type of gemstones is not marked on the piece. Given the style, cuts (oval + pear), quantity, and typical construction of similar sterling silver jewelry, the blue stones appear to be high-quality simulated or lab-created blue gemstones (possibly cubic zirconia / CZ, glass, or synthetic aquamarine/topaz) rather than natural aquamarine, blue topaz, or tourmaline.
