I read about open C-axis in tourmalines but did not realize the effect it had till I saw two tourmalines side-by-side, one with open C-axis and one with closed one. My question is, if one of my stones has beautiful, deep, saturated color but definitely has closed C-axis. I was trying to read about it on another forum, and there was such a divergence of opinions about closed and open C-axis in darker tourmalines... Can something be done to remove the effect? A recut? I have very few tourmalines, but many of you like these stones, and have many, so I hope someone here can give me an advise...
