Narrative:

On final approach right main landing gear failed to extend. Low approach accomplished and tower confirmed right main gear not down. Captain accomplished go-around and declared an emergency. I complied with ECAM and QRH. Proceeded with left/G gravity extension checklist and got three safe gear indications (three green indications on front panel as well as overhead panel). Re-accomplished [approach] and landed without further incident. Maintenance met aircraft and towed us clear of the runway to parking. Great job by ATC.
