Must one believe in the images found on gemstones, and is it permissible to pray while wearing them, especially since some of them contain images of creatures or nude women? Are these images real and depicted by God, and what is the ruling on the agate stone that is said to bear the image of the Virgin Mary?

The question does not clarify the nature of the images engraved on the gemstones, but if they symbolize false deities, then it is impermissible to believe in them; rather, they must be disbelieved. It is not permissible to pray while possessing these stones if the images are of living beings. Furthermore, it is not permissible to wear or keep them if the images are of naked women. The images engraved on these stones are man-made, and the fact that the stone is an agate does not confirm the existence of an image of Mary, peace be upon her. Indeed, the image of Mary that Christians depict today is incorrect and distorts her chaste image.
