pink adjustable ring

So pink seaglass has an interesting history. Originally white , the glass was created around the 1st world war. Up to that point our glass was made using chemicals imported from Germany. When war broke out we had to change the way we made white glass. We used different chemicals but they had the same effect, turning naturally bluey green glass white. However , over many decades the new chemicals started to break  down inside the glass. Turning it pink. So as the years progress the likelihood is that this ring will become darker pink!
