No aroma that I could tell. Weight between light and heavy.It appears too dark compared to all of the redwood burl I've seen. I would expect more pink within.
It should have had a wonderful aroma while turning—sorta cinnamon and yet pine or cedar at the same time.
Is it heavy or light weight?
If heavy, unlikely it's redwood.
I think you're right. I'll go with thuya although my blank is a little darker than the ones I googled.Still say Thuya
