Tourmaline in Quartz is probably one of the widest know and most available of inclusion focused gems. There are many of these from Brazil with Tourmaline in a variety of colors. This gem has two interesting characteristics, the first being the green Tourmaline crystal is exceedingly wide and very transparent in its own right. More often than not, the Tourmaline is rather thin.
And no doubt you have already noticed the second, and absolutely fantastic, quality of this one. There is a broad flash of interference color from the point where Tourmaline meets Quartz inside the stone. The most intense and dazzling iridescent flash we have ever seen one of these have. Easily seen from most angles on this large (1.8 inches in length) gem - many times better in-hand as well. What else can be said? A large and remarkable stone.
