Lavender jadeite from Turkey, also known as "turkiyenite," is a highly uncommon stone that has only gotten harder to come by over the years. Material from this particular locality contains between 40% to 60% jadeite jade (as opposed to the often less valuable "nephrite" jade), with the remainder a still unknown combination of quartz, orthoclase feldspar, epidote, and other trace minerals. AA grade material and better (with the scale starting at D and going up to AAA+) will have a higher jadeite content.
Turkish purple jade has a unique quality called "photoluminescence," meaning a stone's color can actually shift to different shades depending on the light source. Included in the last photo slot is an example of the same several stones under different artificial lighting conditions. No filters or color correcting techniques were used. In direct natural sunlight, the material can exhibit a magenta "glow." In artificial white LED light (such as a phone flashlight), the stones tend to take on a ghostly marbled blue.
