When you put a nephrite, or a jade, a jasper, a quartz, a tourmaline, an agate, an amethyst, a shungite, an Herkimer diamond, a malachite, or a chrysocolla, and many other less audio-wise efficient stones, like ruby, labradorite, fluorite etc., on a Schumann Generator, located in the room, the effect on the sound is VERY SPECIFIC, and none of these stones will act only passively by solely absorbing and transforming vibrations... Some like shungite or lava beads are not even piezo-electric crystals and their working effect is similar in power and they are in fact more powerful, and they must be used with some cautions to be positively effective...
Each stones seems to lend to the S.G. or near the gear where the stones are located, some VERY SPECIFIC quality inherent to their own structure...This quality work actively like a filtering action potential at the acoustical and electronical and electro-magnetic level, all at the same times... This observation of mine is there to convey my impression and is absolutely not science nor scientific, only metaphors...But anyway nobody has never explained to me the facts discovered in these experiments with sound...Perhaps there is a scientist that can, unbeknownst to me; probably, but for the moment I need to hear from him...
