This genuine 4.5 ct Natural Ethiopian Opal is offered at an unbeatable price! A phenomenal opportunity for jewelers, collectors, or anyone seeking a mesmerizing, statement-making center stone for a bespoke piece. 💍 Exceptional Cut & Rarity: Features a perfectly smooth Oval Cabochon cut. What makes this a masterpiece is the breathtaking phenomenon! The eye-clean, clear "crystal" body acts as a perfect window for a vivid, full-spectrum rainbow "rolling flash" that sweeps across the dome as the stone moves in the light. 🌈✨ Gemstone Specs: Measuring an impressive 14.8 x 11.5 x 5.7 mm, this stone offers an incredible face-up spread. Because opal is a lightweight mineral, this gem faces up much larger than other stones of the same carat weight. It is an ideal size (roughly 15x11mm) for a dramatic, high-end cocktail ring or a substantial bohemian pendant! 🛠️ ⚠️ Massive Discount & Incredible Value! Estimated Appraised Value: Premium crystal-body Ethiopian opals with full-spectrum rolling flash of this massive size typically appraise between $450 and $675. ✨ Significance: Opal is celebrated as a stone of pure inspiration, enhancing imagination, passion, and creativity. 📈 Authenticity: Guaranteed 100% natural Ethiopian Opal.
