What Is a Nat Thew Crystal?
"Nat Thew" is a Burmese term for these naturally formed spinel octahedra. Spinel is one of the few minerals that reliably crystallises into near-perfect octahedral forms — eight smooth, triangular faces meeting at precise vertices. In Mogok, these crystals hold cultural significance and are collected by mineral enthusiasts, gemstone specialists, and jewellery designers who want to work with spinel in its most natural state. Each Nat Thew is unique and cannot be replicated. They are suitable for mineral collections, display pieces, and increasingly as raw elements in contemporary jewellery design.
