Hello! I know next to nothing about gemstones and I’m hoping to find some guidance on whether or not these are windows and if I should have the stone replaced. It troubles me that I can see through the stone at different points and it isn’t reflecting light in those spots. From what I’ve read online these are windows but I’m not experienced in identifying them and I was hoping to get an opinion on this specific stone. This is my engagement ring so I really want it to be perfect, and I kind of hoped/expected that it would be blue all over. If these are indeed windows and you know of a trusted place where I can order a loose sapphire, please recommend! Thank you in advance for any help you can offer!
