What is Green Tanzanite?

About twenty years ago vivid green Tanzanite hit the market for a very short time.  This material was similar in color to chrome Tourmaline and was very attractive and quite valuable.  Material that is available today has a mix of yellow and or blue with the green and is not as desirable or as valuable.  This material is valued at a much less than the comparably sized blue violet Tanzanite and will not likely increase significantly in value as is expected for blue violet Tanzanite.  Sometimes referred to as  party color Tanzanite.
