When you choose Brazilian Rosewood, you are, in a sense. investing in  a piece of history.
This type of wood, Dalbergia Nigra, as it is technically classified, has been on the endangered species list since the early 1990s, and becomes increasingly rare as time goes on.

As you can see in some of these images, it can be strikingly beautiful.
It was the wood of choice, when it was readily available, for most classical guitar builders.

The more exotic the grain patterns, however usually mean that the wood has been slab cut, and if not care for properly, the wood will sometimes crack.

Make surre you are aware of this especially in the cold weather when there a heaters on, beacause the  heat dries ou the air and the guitar along with it.

Take extra care to humidify your guitar and be mindfull of the Relative Humidity.

I do not guarantee against cracks of any kind.  I will do my best to fix a crack, but will not take responsibility for a crack.
