White Fire Opal round stone rings are beautiful pieces of jewelry that feature white opal stones with iridescent flashes of color, often set in various metals like silver, gold, or platinum. The "fire" in the opal refers to the play of colors—blues, greens, reds, and other hues—that can be seen when the stone catches the light.

1. Stone Shape: Typically, these rings feature a round-cut opal, which showcases the stone's unique play of colors effectively.

2. Metal Choices: Common metal settings include sterling silver, white gold, yellow gold, and sometimes rose gold, depending on the desired aesthetic.

3. Designs: Designs can range from simple solitaire settings to more elaborate ones with additional accent stones like diamonds or cubic zirconia.
