This example is noted for its "Flagstone-style Pattern," a rare and visually distinctive arrangement of color patches resembling the irregular shapes of flagstones. Such patterns make each opal unique and especially prized by collectors and designers. Certified by the International Gemological Institute (IGI), the gem's authenticity and type are verified. High-carat, vividly patterned opals are captivating souvenirs from nature's diversity and are treasured in jewelry and mineral collections worldwide.
