The internal cracks that you see in the rose quartz egg are normal to the material. If, however the egg start to chip, or peel, or external cracks (the cracks you can feel with your finger) start to emerge, then the stone’s integrity has been compromised (this is likely to happen if the crystal was dropped on a hard surface). In this case please stop using the egg immediately.
Please also keep in mind that we do not treat our crystals with fillers or resins and due to the nature of the rose quartz crystal most stones will have surface level indentations. Shallow surface level indentations and cosmetic scratches are ok if they clean easily with water and if they do not have sharp edges.
