Central Gemstone: The ring features a stunning oval-cut gemstone in the center. Based on its deep, saturated blue color, it is likely a London Blue Topaz, an Iolite, or possibly a Sapphire.
Halo Setting: The central stone is surrounded by a "halo" of smaller, round, colorless stones, which appear to be diamonds or cubic zirconia (CZ). This halo accentuates the size and brilliance of the main stone.
Band/Shank: The band is made of a white metal, typically White Gold or Sterling Silver, and features further accent stones set into the shoulders of the shank, adding extra sparkle.
Overall Look: It is an elegant and classic design that offers a lot of brilliance and color. It's a popular style for both engagement rings and dress/cocktail jewelry.
