Karaköy Restaurant is a restaurant or bar in Karaköy, Istanbul designed by Interior Design: Ypsilon Design, opened in 2021. Hospitality interiors like this one specify stone for atmosphere as much as durability — the surface has to look good under the exact lighting the designer chose, at 9pm, not at noon. To be clear: this is not a DIJA project, and we did not supply the material — it is included here purely as a documented reference.
What the record actually lists, surface by surface: floors: bosphorus grey marble; bar counter: skyline marble.
For bosphorus grey marble, we do not carry that exact quarry block, but a very close relative is Bianco Carrara CD. For skyline marble, the closest thing we sell to it is Calacatta Oro.
The original project write-up, with full photography and credits, is linked below — we do not reproduce it here, only the facts.
