Hello, I’m trying to identify this specimen. It was found in San Juan Cty UT in an area where petrified wood is common. The left end (large end) appears to be where a stem attached. There is a seam the full length. It looks like a large petrified seed pod. The specimen was broken. I attached pic of broken end.

I found this last year at the Sunnyside mine, Eureka mining district, San Juan county Colorado. My initial thought was this is Lapis, however I have seen specimens of lapis that do not look quite like this. Thank you for any input.
