Green tourmaline is awesome. It is like - like standing in hip deep water, by a dock; it has this kind of swirling, loving, emotive pull to it. It does deepen one's heart sensors; you may feel like you are feeling more, and more deeply.
Lovey stone. Works super well with pink tourmaline, if you are planning to open heart chakras, as pink guides self-love, or lower heart chakra, and green guides compassionate love for others, or upper heart chakra
And of course, black tourmaline will work well with it too, as a grounding stone - so you don't get caught up in emotional tailspins...
I love tourmaline in all forms, for emotional work. It is like the Cups suit of the tarot

Enjoy yours, Eva!
