While en route at FL430; approximately 45 minutes into the flight; we received an amber 'RT WINDSHIELD HEAT INOP' CAS message. This was followed shortly thereafter with a 'LT WINDSHIELD HEAT INOP' message. My partner noticed some flashing of sparks in his windshield (right); then a few seconds later it shattered. We complied with the appropriate checklists and declared an emergency. I then advised the company and the passengers of the situation; and that we were diverting. We landed uneventfully.
CE750 Captain reports right and left windshield heat inoperative CAS messages at FL430; followed shortly by the First Officer's window shattering. An emergency is declared and the flight diverts to a suitable airport.
