Physical properties
Hardness varies from 3-3.5 (Celestite) to 7 (Quartz family) and 9 (Ruby in Zoisite). Colors include purple, light blue, bright pink, blue-speckled granite, and deep magenta. Vitreous to dull polished luster, smooth tumbled forms.
Formation & geological history
Comprises various rock and mineral types from diverse geological settings: igneous pegmatites (Amethyst, Rose Quartz), hydrothermal veins (Celestite), metamorphic zones (Ruby in Zoisite), and high-altitude granites with azurite (K2 Jasper).
Uses & applications
Popular for lapidary art, crystal healing, educational rock collections, pocket stones, and decorative displays.
Geological facts
This photo shows a labeled assortment of small tumbled gemstones on notebook paper, including K2 Jasper (azurite in granite from northern Pakistan), Celestite, Amethyst, Rose Quartz, Ruby in Zoisite, and Que Sera Stone.
Field identification & locations
Collectors identify these by their distinct colors, inclusions, and patterns—such as the bright blue azurite orbs in K2 stone or the green-and-pink contrast of ruby in zoisite. Commonly found in specialty rock shops and gem shows.
