.... And for all it's worth , take a look at this. Whether the specific claims have any basis, I don't know; but I DO know, from experience, that GEMS DO HAVE HEALING PROPERTIES. Not sure how it works.

IMMUNE BOOSTING GEMS

http://www.daikomyo.com/HealingPropertiesofGemstones.html

The gems stressed for IMMUNE BOOSTING are

 QUARTZ,

CITRINE ( a yellow form of quartz),

 LAPIS,

MALACHITE AND

TURQUOISE.

Not expensive gems at all.

Interestingly, two of those, Malachite and Turquoise, contain COPPER.

Aryeh asks:

What are you supposed to do with the gems?


DS replies;

If you ask me: LOOK AT THEM, and HOLD THEM in your hands.

Just looking at them, I felt an effect, specifically from the CITRINE: it gave my body a desire to fight, it strengthened me.
