Uluru Truly is the Hearth of Australia

Uluru (Ayers rock) in Australia was a real Heart and the blood ran out and created the BEST OPALS in the world. The thumbnail is cardiac muscle that the blood eroded out. The chemistry is COLORFUL. 95% of Opals in the entire world come from right next to Uluru because blood contains transition metals that are very invasive (nucleophilic invasion) and the tissue types take on SPECIFIC COLORS (look them up).
