1.Weathering Marks are signs of aging. They best represent the age of a Dzi. If we examine a Dzi under magnifying glass, we will discover tiny lines of different thickness running irregularly and spontaneously on its surface. These are weathering marks. They resemble either fish scales or phoenix claws.
2. Sheen:- Age and natural weathering might result in a slightly rugged patina that confuses the reflective light. We can see with our naked eye that there seems to be a layer of oil on the surface of the Dzi. We can call this "oily sheen". Some particularly bright oily sheen can be called "waxy sheen".
3. Cinnabar Dots "Cinnabar Dots" are in fact red speckles that grow from within the body of the Dzi to its surface. Not every Dzi has cinnabar dots, and dzi with such dots are not necessarily good qulity Dzi. This is the often used as a criterion to identify old Dzi beads.
4. Crystal and Natural streaks Although the Crystal and natural streaks will affect the grade and price of Dzi bead, but its a rarity among new dzi.
5. Dig marks for medicinal useDzi bead is a precious medicinal ingredient in Tibet, they chipped off in the corner for medicinal use. Usually, the new dzi bead are perfect in condition, they never spend time to do this. If dig marks are not doing well, the result is break.
