Just as Kailasa is the abode of Shiva, ‘Sphatika’ is the gem of Mahadeva. Hence it is also called ‘Shivaratna’. According to the scriptures one side of the Kailasa is made of ‘sphatika’ (quartz). Pink/Rose quartz is especially energizing because it is embibed with the ‘blazing force’ of the Bhairava. Hence rose quartz mala is especially recommended for chanting of the Kailasa Mantra during puja.
