Wow! quite an ordeal, dealing with bad energy in stones!
Good choice of stones @onetree, for both are very protective and always 'good' for you even though they may feel exhausted from time to time. I once asked one of the best crystal healers about the one stone she would choose for herself. She said 'smokey quartz!'
For laboradite, this is also my favourite crystal. Highly protective and magical. I always have them close to me.

Good job, you got rid of the bad agate! Stones have memories of their owners and surroundings. I almost threw up in a Chinese man's storage room full of unwashed stones; I could hardly breath and felt an acute headache. I had to run out of the door to breathe and recollect myself. Then, with conscious determination I entered the room and did something to stop their disrespect! It did work and I stayed there for almost three hours.
Another time was when my friend proudly showed me the latest imported stones. As soon as he opened the brown package, I ran outside the shop to throw up! I told him where the stones came from and the conditions or surroundings under which these stones had been handled. He was shocked as I was correct about the source of these stones. I told him to wash these stones at once. He took some time to clean these and came back to show them to me again; all the negative vibs were gone.

Always listen to your inner voice and intuition; you are very sensitive and psychic, and so is your family. Some stones are just beyond our ability to help them, some are just too nasty and aggressive. I always stay away from bad stones. It's funny how I only go into some crystal shops; there used to be lots of crystal gurus and shops in Bangkok a few years ago. Nowadays, crystals business is very slow and prices have become more affordable.

I think you know how to handle the stones with bad attitudes very well. Stay away from 'mad dogs'.

Cheers.
