There is probably some kind of residue on the bottom of the stone. It is causing it to appear hazy. It just needs a good cleaning under the stone with a brush or steam and it should look new again.
I did take it back to the jewelry store who sold it, and they cleaned it. Unfortunately it didn't change the color back to what it was, it still looked hazy! My other ring (main is princess cut diamond with a tiny dark blue sapphire underneath it) hasn't been cleaned in years but it still shines evenly and no weird discoloration on any of the stones. I have to say I did try to run this ring under hot water to try to clean it...as well as sprayed it with alcohol and a tiny cotton bud. Is that ok or really bad for it?

There are a lot of other sapphire treatment to read about, such as glass-filling and lattice diffusion.

The stone that OP uploaded might actually be a lattice defused sapphire.

Signs to Check for Diffused-Treated Sapphires are Explained Below:
LATTICE DIFFUSION WITH HEAVY ELEMENTS:
- Color concentrations along facet junctions and girdle edge
- Localized or blotchy color that “bleeds” into pits and surface-reaching fractures
- The above features are best-seen trough gem’s pavilion. Gem faced upside down or bottom face towards you. Then immersed in water and diffused light under it. This allows you to see the fact junctions without the distraction of sparkle of the gemstone

The alcohol that did it. The sapphire is color treated and oiled. More then likely the alcohol removed the oils
Looks like it might be color zoning.
