The wispy inclusion in the larger shield cut are hard to see. The green is brown down a bit, but it is still a bright flashy gemstone for a medium dark tone level. It weighs 6.23 carats.
The wispy feathers in this larger medium plus toned shield cut are hard to see (best from the pavilion) and do not effect the flash. The green is taken down a peg with a brown overtone in daylight, that is much less apparent in yellowish light. But if we are going to count pegs, this is a cuprian tourmaline and that does bring it up a peg in my book. I did not know this gemstone was copper bearing when I bought it and only discovered the fact with my spectrometer. I have no idea whether its copper content is actual making a significant contribution to the gemstones color. I does help make the shield cut unique in the collection.
The bottom line with this stone is a complex mixture of wispy feathers that are common in cuprian tourmaline, a fine tone level of medium plus with a nice yellow green color slight modified with a brown overtone. At 6.23 carats it is a fine sized for a shield cut.
