right|thumb|palm islands with the world and the universe archipelagos design view the palm islands are two artificial islands, palm jumeirah and palm jebel ali, on the coast of dubai, united arab emirates. as at november 2014, only palm jumeirah has been completed. this island takes the form of a palm tree, topped by a crescent. when complete, palm jebel ali will take a similar shape; both islands will be host to a large number of residential, leisure and entertainment centres and will add a total of 520&nbsp;kilometres of non-public beaches to the city of dubai. the creation of the palm jumeirah began in june 2001. shortly after, the palm jebel ali was announced and reclamation work began. a third island was planned and construction started, but this project was later remodelled and renamed to deira island. ==construction==  the palm islands are artificial islands constructed from sand dredged from the bottom of the persian gulf by the belgian company, jan de nul and the dutch company, van oord. the sand is sprayed from dredging ships, guided by a global positioning system, onto the required area. the spraying process is known as rainbowing because of the rainbow-like arcs produced in the air when the sand is sprayed. the outer edge of each palm's encircling crescent is a large rock breakwater. the breakwater of the palm jumeirah contains over seven million tons of rock; each rock was placed individually by a crane, its position signed off by a diver, and given a global positioning system coordinate. the jan de nul group started working on the palm jebel ali in 2001 and had finished by the end of 2006. the reclamation project for the palm jebel ali includes the creation of a four-kilometer-long peninsula, protected by a 200-meter-wide, seventeen-kilometer long circular breakwater. there are 210,000,000&nbsp;cubic meters of rock, sand and limestone that were reclaimed (partly originating from the jebel ali entrance channel dredging work). there are approximately 10,000,000&nbsp;cubic meters of rocks in the slope protection works. ==palm jumeirah==   the palm jumeirah ( coordinates:  ) consists of a tree trunk, a crown with 16 fronds, and a surrounding crescent island that forms an 11&nbsp;kilometer-long breakwater. the island itself is five kilometers by five kilometers. it adds 78&nbsp;kilometers to the dubai coastline. residents began moving into palm jumeirah properties at the end of 2006, five years after land reclamation began
