What are these!?

[Alicia728]

I have been given a few different opinions. Tanzanite, sapphire, or treated diamond. One jeweler I had glance at them dismissed them as being glass, yet offered me $20 the larger stone has 2 inclusion visible to my untrained eyes..any opinions or input are welcome!

The color looks like tanzanite. If you place it on a white cell phone screen and rotate the stones on each side you see change in colour in different direction should be tanzanite

What is a white cell phone screen? Like when I opened a new page of Chrome?
