We have three sizes of rough ruby. The medium is approximately 1.5-2.5cm across the widest points. The medium is approximately 2.5cm -4.5cm across the widest points. Some are flatter, some are chunkier. Some contain a spiritual key, others don't. They are mainly hexagonal but as they are rough, they do not form perfect hexagonal shapes. Some are deeper than others and slightly less regular.
