Mark.,
As always very beautiful bows.
Thank you for posting.
HatchA,
There are various other woods that are known as rosewood or have rose in their name, if you cannot find Brazilian have a look for Indian Rosewood we even a have a gum in Australia that goes by the name of Rose Gum, it is not that hard and fairly low in density only 620 Kg/M3 but probably would make an inner lam.
Hope you find your wood.
Craig.
