From a find of this spring, this is an unusual yellow-green titanite that changes the yellow/green balance of its hue depending on lighting and in any case is more yellow than traditional Brazilian sphenes have been. The major faces are clean though chlorite is ingrown into the twinning planes as is the case on most other Brazilian sphenes from previous finds. My understanding is that this small pocket yielded under a dozen really good specimens. This particular specimen is very large and impressive visually, and features a perfect, 3-inch (8 cm) twinned crystal perched vertically atop smaller crystals with twin planes shooting in every direction! That large twin has a minor amount of the rightmost termination missing, or contacted (I honestly cannot say which), and hence the low price. It displays very nicely despite that small defect and LOOKS like a much more expensive specimen 10 x 8.3 x 7.1 cm
