GR9-Here is a good example of a Tanzanian color change sapphire. According to gemval (0413452540 gemval1@gmail.com) the color change was tested to go from a light olive to a deep pink under incandescent light& is considered to be 100% color change. While they consider the cut good there is some chipping on the girdle & facets. This stone would be excellent for those like us who are fanatical collectors & love their sapphires. Sapphires provide such an excellent range of color & unusual properties & inclusions, as well as excellent hardness (moe’s scale (9)., the king of stones. This was evaluated by Gemval $3477Aust.…our price…$1150 USA. .  There will be postage costs, depending on where it will be going. will have to work that out when sold.  please feel free to check Gemvals credentials. After we listed this stone the gemologest had a second look at it and we found it also fluoresces when a laser light is pointed at it {see photo}. We are yet yo test it under a black light to see if the same thing happens!
