What is Pink Tanzanite?

For some time I thought the only pink Tanzanite was thulite the massive form of Zoisite, the parent mineral of tanzanite.  Recently I have seen fine pink facetted tanzanite, more properly call Pink Zoisite.  The color is light to medium saturation looking similar to fine Pink Tourmaline.  What I have seen is only in sub carat sizes at prices 10 times that of the comparably sized blue violet Tanzanite.  Due to extreme rarity the value is determined by the seller and not based on a market value.
