Rosewood is most likely a real wood inlay / laminate in this application. The cracking would be caused by the substantive wood, normally a soft wood so easy to absorb moisture, being subjected to the " real world " humidity rather than your homes settled temperature + humidity.
My guess, as you have not submitted a picture, is the carcass wood has swelled and split the inlay.
First thing is to let the wood settle down over a few weeks in your home. Even though this time of the year most of us are not using air con, your home will have a " drying airflow " unlike the sealed box container it traveled in, which has , in effect acted like a sauna.
If the end result is that the cracking is still obviously evident then its a job for professionals like french polishers, who will fill the gap and stain to watch the tenor of the wood.
There are no FP's in Yellow Pages but there is Furniture-Repairing & Refinishing and that would be a place to start.
