Bomb Party Resort Wear ring, "Oceanic Dreams" (RG73779), size 10. New in the original Resort Wear box with the item card.
It's a bypass-style ring with two cushion-cut white stones set at opposite ends, connected by curved bands lined with sparkly clear CZs. It sits at an angle on the finger, so it looks bigger and more modern than a regular solitaire.
The stones are lab-created white quartz fused with genuine quartz, which gives them a soft, frosty look. Silver plating.
