Nondalton

"Nondalton" refers to a classification of minerals, specifically in the context of gemology and mineralogy. It describes gems or minerals that do not exhibit strong or distinctive optical effects such as color change or pleochroism, which are characteristics seen in some other stones. In gemological terms, a nondalton mineral typically has a more uniform appearance under different lighting conditions and does not show the vibrant shifts in color that can be typical of certain stones. Understanding whether a gemstone is nondalton helps gemologists assess its quality and value in comparison to more visually dynamic minerals.
