Constellation (864) #2 is a sparkling, golden pewter with a metallic finish. It is the sparkliest shade out of the five, but it binds well together and applies smoothly without causing fall out. MAC Greenluxe #2 is lighter, more golden. MAC Antique Diamond is darker, cream. See comparison swatches. I thought it was going to be easier to dupe, but shades I thought would be similar were much darker.
