Beautiful blue stone on a .925 sterling silver setting, NWOT size 6

NWOT, I believe this is by Ring Bomb Party, but no original tags or info available, was an estate sale item. Stamped .925 Size: 6 Reasonable offers are always welcome! Brand new item, with only size tag attached from a smoke free home. Your business is appreciated .Due to the difference between different monitors and lighting, the picture may not reflect the actual color of the item. Thank you! BX2A2
