What a cool colors! What is difficult to see in this image is that there are beads on the side of the shawl. You can crochet this shawl with one ball of Scheepjes Whirl (very nice yarn by the way). The pattern is very well explained and there is also a chart available.
You can find the free crochet pattern of the My Voyage Shawl on the website of Look at What I Made.
