Shopping for Healing Crystals

Since a lot of my jewelry and inspiration for my shop is based around healing crystals, I thought I should post a little about how all of that works. I'd like to state that I'm but a beginner on all of this, and am still learning my way around. If you have any questions I will of course try and answer them to the best of my ability, but may have to direct you elsewhere.

To go out and buy healing crystals without knowing their function/how they heal, or without having some type of pull towards them is essentially going to turn into you collecting rocks- in which case that's totally cool, because we've all been there, but for the purpose of collecting healing crystals, it's much more than that.
When you're buying healing crystals, focus on how you're feeling. Do some research prior to shopping and see which stones mean/heal what. Getting stones that pertain more to how you're feeling will help you more in the long run compared to just buying stones because they're pretty. Another thing you should focus on when purchasing crystals to help you, is to see which ones you have a natural pull to. When simply viewing the crystals, or holding one in your hand, you may have a certain energy expend from the stone to you, and this is a good sign and something you should look for when investing in stones.
