Is it true that a crystal mounted in silver (ie, to be worn as jewelry) is better than mounted in gold, because gold 'blocks' its powers somehow? I heard that but am not sure if it is true. If it is true, then why?

Gold is called the devil's urine, but I'm not sure they mean it to be an evil thing. The only piece of gold I have hurts to touch, which is my ex's necklace.

Hurts emotionally or physically? Not sure what you meant.

I had a friend who turned gold black when she wore it, it was very strange!

Devils urine eh? Not a nice name Not heard that before.

I would think that your friend was wearing 9ct gold? That can easily turn black or even green depending on when and where it is worn because of the impurities included in it.

It is far easier and cheaper to wear almost pure silver like fine silver which is 99.9% pure or sterling which is 92.5% pure silver and 7.5% copper. Less impurities to cause allergies and a lovely product uncontaminated by more dangerous heavy metals.

When choosing a gemstone setting, 'gemology' asks for a precise measurement, weight and setting of gold or silver but crystal healing only asks that the stone be set happily, ideally for most, with an open back so the stone can touch the skin, and an open end so the crystal can breathe and save itself.

Jallious perhaps that is to do more with karma and negativity than the actual gold?

That is really interesting Gem. Thanks. You certainly know your stones!
