Is it true that wearing gemstones actually has an effect on health and luck and improves them?

Yes, it is true that gems really do have an effect and possibly improve health. But first you have to see your horoscope. If the horoscope says that gems have an effect on life, then it is sure that gems are helpful for your life.

Gemstones only improve the health and condition of both the seller and the wearer possibly.
Yes, it acts as a placebo, which in turn has a positive effect. But this cannot be attributed to the gem, it would be effective in the form of a ring or pendant made of precious metal, which in turn is being worn by a person with positivity and hopefully it is really helpful.
Gems do not attract gravity from Saturn or Jupiter, nor do some cosmic rays. If diamond is effective, then other gemstones also .

We followed the advice of astrologer and taken one Pearl ring. Felt a positive change in few days of wearing. It had effect on the mood after wearing.

Possibly gemstones have an effect if taken advice from astrologer.
