Dad said no and said he’s seen ones exactly like that at a local brick shop where they can be bought buy the bucket, rather than $3.50 per crystal.

Would these be suitable for crystal healing? Would they have the same effect?

Useful answers only thanks, no skeptics. Anything rude and your answer will be reported.

Otherwise please help, i don’t know whether they’d have the same effect, thanks in advance.

The energy fields present in a crystal were formed during the crystal’s creation in the earth. There should thus be no difference between the one bought from an expensive shop or one that you pick up in the street. The only difference is knowledge. A crystal shop of good reputation would help you choose a crystal that is right for you and fit for purpose.

Choose a crystal by holding it in your hand and sensing if it makes any difference to you. If it feels energising or warming, it would indicate that the crystal is "in tune" with your own frequencies. Take it home, soak it in salt walter overnight to clear it from any previous contamination. Start working with it. You will soon know if it is the right crystal for you. Treat the crystal with good intent, cleaning it occasionally to clear any negative energies. They become your friends forever.

New Age – rhymes with sewage!

To find out if a crystal is alright to use, hold it in one hand. With the other hand, take your thumb and index finger and gently rub them together. If they glide smoothly over each other, the crystal is ok. If your fingers feel sticky as you rub them, don’t use the crystal. This can change on a daily basis. One day it might be fine and the next day it won’t. You may use this method to see if your body likes other things such as fragrances, jewelry and even food.

He’s seeing a physiotherapist because he’s a drummer and has been getting really painful wrists – it’s improving now since he got his neck cracked to align the spine and nerves, but maybe there might be a crystal he could have by him whilst he’s sleeping to help it from getting worse again?

Keep with the physiotherapist. He also might want to begin taking a glucosamine/chondroitin/MSM supplement. This is awesome for joints as it lubricates the joints, repairs the joints, and stops the inflammation. For a crystal, you might want to get a Tiger’s Eye with some turquoise. These are often made into awesome jewelry for men, so he wouldn’t need to know your purpose in the gift.

Black Onyx – it works especially well to help keep a person stay grounded within themselves regardless of what is going on around them.
When people at my work are trying to get me to do things for them all the time [when they could think things through for themselves with a little bit a thought ], wearing a black onyx bracelet helps to keep me grounded and focused on what I think is important to spend my time <except when the boss asks me for help, of course…lol>

Together:
Gemstones are vibrationally strong, and will align you gently but surely to "their energy". So wearing them together won’t change their separate effects. Try experimenting

I hope the above helps
