When we bought these slabs they were labeled Flamewood.
The one in front is has poly on it, the two to the right have only been skipped planed.
Some searches have taken me to Siam rosewood but two things tell me it's not - 1. I paid about $11/bd.ft. for it and 2. Siam rosewood is very rare and on the CITES endangered list. I've seen prices for Siam rosewood comparable to Gabon ebony, sometimes even higher. But the curvature of a Siam rosewood tree matches the curvature of the slabs I have.
Flame box elder also came up in my search but that doesn't look like it either.
The only image I have found so far that looks close is this
They don't identify the wood only that it was salvaged from a yard in Pinellas County, FL. I bought those slabs in Sarasota County so there may be some connection to Florida grown woods.
I realize the term "flame" can be used for practically any wood that has figure. When I asked the sales rep about the wood, she told me it was very rare and it could be a year before they see it again, if ever. That they were selling it for $11/bd.ft. made me wonder about the "rare" status but I loved the figure so I bought it.
Any ideas?
