No reserve price White, Multicolour Opal - 7.23 ct - Antwerp Laboratory for Gemstone Testing (ALGT) - Fine Color Quality

Opal is celebrated for its unique play-of-color, which refers to the gemstone's shifting rainbow-like hues visible within a white or multicolor background. Formed from hydrated silica, opals can display a kaleidoscope of colors due to the diffraction of light caused by the stone's internal structure made of microscopic silica spheres. White opals, often called milky opals, serve as a classic type displaying a light, translucent body color with flashes of various colors. Opals are prized both in the jewelry world for their iridescence and by collectors for their fascinating natural patterns and formation. Their delicate nature requires careful handling to preserve their dazzling effect.
