CE525 flight crew experienced a pressurization anomaly during descent to FL320. The flying captain continued the descent without advising ATC while the first officer had his headset off while donning his oxygen mask. Eventually ATC was advised and the descent was continued to 10000 feet with the cabin never exceeding 14000 feet.

Narrative:
This was a charter flight with 2 passengers. Our cruise altitude was FL430. When center gave us our descent for landing we experienced a loss of cabin pressure. Around FL320 we started an emergency descent and communicated that with center. At 10;000 feet the emergency was over and we asked for the RNAV GPS approach. The weather was clear with 10 miles visibility. The landing was uneventful the passengers were safe. The aircraft was taken for repair at the [maintenance center]. The outflow valve was replaced; we then flew it to home base at FL410 without incident.
