Narrative:

I was the pilot not flying while on the descent and flying a heading. ATC notified us that there would be an opposite direction embraer flying through our altitude; and asked if we had it in sight at 12 o'clock. The captain and I noticed a bright light in the distance; but it appeared to not be moving. So; we called negative on the traffic. Monitoring TCAS; we began to watch for traffic climbing towards our route of flight. ATC frantically asked us if we had the traffic. At that time we had the traffic in sight and began a right turn and received a 'climb; climb' RA. I notified ATC of the RA and that we were turning right of course. The other aircraft stated on the radio that they had an RA as well and were descending. Per the TCAS the closest we got was about 800 ft vertically and something less than a mile horizontally. ATC then assigned us a heading again and said to continue the descent to 8;000 and to contact approach.
