Narrative:
En route we were at FL450 in order to top weather and provide a smooth ride for passengers. The cabin pressure suddenly began to climb at approximately 1;000 ft per minute. We donned the O2 mask; dropped the mask for our passengers and began a rapid descent to the requested and assigned altitude of FL340. We performed the checklist in accordance with company SOP's and continued the descent to 10;000 ft and then with the company's input; diverted and made a normal landing.
