Firstly, welcome to the wonderful world of crystals! Secondly I would hope to be of some assistance to you.

I have a few websites that I trust that use as a reference for gemstone's metaphysical properties. Note, that neither of these have every type of stone listed that you may come across. This is a terminology catalog of various gemstones, and this one is a very comprehensive guide on metaphysical properties. There are of course more out there, but I use these two more frequently.

Crystals are helpful for spiritual, mental, and emotional healing which impacts the overall physical body in a holistic manner. I have used my crystals for all of the above, mostly for meditative purposes to deal with my anxiety. I also have used my crystals for ancestral healing, intuition work, etc.

I wouldn't say that crystals are really either new age or a part of hinduism, but knowledge on their use and some concepts come from hinduism and also come from new age ideology, (most notably the chakras, the divine feminine, and how crystals have energy and even aura).

This isn't just a hobby, but in fact a spiritual practice, at least for me.

So you want to visit Sedona, AZ before you move out of the state entirely? Why are you still with this boy if he is mentally abusive? You are worthy of so much more OP, more than someone who intentionally hurts you. Sedona is a very magical place, it wouldn't be enjoyable with someone who will only perpetuate your trauma.

It sounds like your heart chakra is out of alignment and wants comfort. For this, a lot of green and pink crystals namely rose quartz and moss agate help with moving on and establishment of abundance and self love. For negativity repel, black tourmaline and shungite are the most powerful in this sector.

As for your attraction to moonstone, it only makes sense with regards to what you have disclosed above. Moonstone is a feminine stone of healing, fertility, and spiritual growth. It is a stone of creativity, intuition, and empathy, with radiant moon energy. Moonstone is gentle in its work and some specimens, in particular, rainbow moonstone have been known to showcase blue flashes of light with specific angles.

I hope this helps!
