Finishing Morado (aka Bolivian Rosewood)

DAGS found one article indicating that Morado "reacts poorly to some
oil finishes". No more info given. The same article indicates that the
wood color may fade on exposure to sunlight (UV I assume).

I've put together a ring box of Morado and qulited maple (kind of a
spectacular contrast) for my wife for Xmas. I'd like to avoid any
fading of the Morado but still get the maple grain to jump out. Plan
was to use Waterlox until I read the article as I've had good luck
with it on other figured maple works.

Any experience with finishing Morado or thoughts on finishing the box
would be appreciated.

Regards.
