1kg Tumbled Stones Bulk Mixed Crystals Gemstones S - M - L - 10-30mm Wholesale . Each 1kg bulk pack offers a variety of genuine grade A gemstones, meticulously polished to showcase their inherent luster and charm. These stones are categorised by size, ranging from small (S) to medium (M) and large (L), each measuring between 10-30mm, ideal for meditation, display or creative projects. Bags include: Obsidian, rose quartz, selenite, malachite, blue lace agate, cherry quartz, jasper, moonstone, labradorite, lepidolite, sunstone etc etc. Bags are mixed so some bags may contain more of one stone than another but I have tried to mix them as evenly as possible.
