Raw crystal have either been broken or cut off of a larger geode/ form and may appear rough as that is how the earth made them. Polished Crystals have been shined and smoothed to enhance each piece's features. Some prefer the natural look and some the latter, but "to each their own!".
Our "Crystals" collections include pieces that have fully formed into a single crystal, a cluster of crystals, such as our Cut-Base Amethyst, and crystallized minerals such as Malachite.
