There are certain stones which I feel belong in every crystal collection. These include clear quartz, amethyst, and rose quartz.
Amethyst is a color which many people consider to be that of spirit.
Self-love is important for everyone, but it is especially vital for people who are interested in spiritual development. Any negative feeling is a kind of psychic glue which attaches us to that about which we feel negative. So with ourselves. When we don't love ourselves fully we are wounded inside, and a wound will always cry out to be healed. Rose quartz is an instrument of that healing.
