So, my friend just purchased this tourmaline. The color is lovely and she loves how it is brighter blue green on one side and a more grass green on the other. What she's not sure about is the stripe (?) that is visible right down the center of the stone. Is is a window? Just the nature of the stone? The cut? We are both novices when it comes to CS, we like pretty rocks, but are definitely not experts. Is it something that might be corrected when it is set, or will it always be visible? Any advice would be greatly appreciated!
