Just bought the pride of my collection! The seller told me it was unearthed in 1992!

Just bought this beautiful tea caddy for 15$, it’s about 12cm tall (4.7 inches), Geiger counter says it’s 0,98 uSv max. The seller told me she got it from one of the builders who dug it up while building a stadium nearby back in 1992, I’m thinking it’s cream uranium glass, what do you guys think?
