I may be wrong, but in general, if something fire-like is added to a stone type or gem, it increases its potency or at least purifies it. So a regular sapphire is not as strong as a star sapphire. Opal vs. fire opal, ignoring the rarity part, of course. I happened on some mahogany obsidian with these beautiful ribbons of rich brown/red -- for me, it worked differently than regular black obsidian, it was more accepting, almost like a sponge.
Another point, I often work from the largest amount of the mixed mineral. So it might be the Sodalite with the feldspar as a helper. A tourmilated quartz has more quartz with the other mineral acting as a directional element. But that's my experience. I hope you have fun with your new stone.
The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.
