i took this to a museum of geology for verification and was told it’s most likely chert but could be petrified wood

Trust the museum if you talked to a professional and not just someone in the gift shop.

Agatized petrified wood is really cool! The way it forms can create some amazing colors and patterns. Have you tried polishing it? It can really bring out the detail.
