Diamond of Istanbul is the tallest building under construction in Istanbul, Turkey, being built on the Büyükdere Avenue in the city's Maslak central business district of Sarıyer. It is also the country's first steel skyscraper. When completed, it will rise 63 floors above ground level and reach an above-ground height of 311 meters. Its design, by Dome Architecture of Istanbul, comprises three steel wings connected to the central (concrete) elevator core. The three wings (towers) will house a luxury hotel (the tallest tower), A-class offices (the second-tallest tower), and rental skyscraper apartments (the shortest tower.) The tallest of the three wings (the hotel tower) will have an overall total of 63 floors above ground (three retail facility floors, 48 hotel tower floors and two panoramic restaurant floors above the hotel floors, at heights of 249.10m and 263.10m, respectively), and reach an overall structural height of 311m from street level. The steel wings rise from the common podium of a shopping mall comprising five floors - three above-ground and two below. The complex also has a five-floor parking garage situated in the bottom-most basement floors of the building (with a total of eight basement floors below ground level.) The panoramic restaurant on the top-most floor will be at one of the tallest man-made points in Istanbul and Turkey.

Maslak is one of the main business districts of Sarıyer, Istanbul, Turkey, located on the European side of the city. It was formerly an exclave of the municipality of Şişli, though being far north and actually closer to the municipalities of Sarıyer and Beşiktaş. Therefore, a legislation was approved by the Interior Commission of the Turkish Parliament on October 18, 2012, that shifted the jurisdiction of the Maslak district from Şişli to Sarıyer. Maslak is in direct competition with the nearby Levent business district for new skyscraper projects. At the present, the tallest completed skyscraper in Maslak is the 47-floor Spine Tower which reaches a structural height of 202 meters; while the tallest skyscraper currently under construction in Maslak (as well as Istanbul and the rest of Turkey) is the Diamond of Istanbul, which comprises three centrally-connected towers, the tallest of which will have 53 floors above ground and will reach a structural height of 270 meters (thus surpassing the current tallest completed skyscraper in Istanbul, the 54-floor, 261 meters tall Istanbul Sapphire in the nearby Levent business district.) The Diamond of Istanbul will also be the first steel skyscraper in Turkey, where (as opposed to the situation in the United States) constructing with steel costs more than constructing with concrete. The reason for choosing steel was its relative strength in resisting earthquakes (Istanbul is located along the North Anatolian Fault), whereas concrete is more fire-resistant. The stations İTÜ-Ayazağa and Atatürk Oto Sanayi of the M2 line of the Istanbul Metro serve the Maslak business district and its surrounding neighborhoods.
