It does come from Brazil and it is a Rosewood but it's not Dalbergia Nigra.
It's Dalbergia Cearensis; Kingwood.
What you show is highly figured but there is no burl.

Same specie as this one.
Brazilian kingwood and Mexican kingwood are both superb and underutilized cue woods. I prefer the darker varieties of each.
