Thanks to its crystal chandelier, sapphire blue sofa and amethyst accents, this modern Fifth Avenue penthouse looks as elegant as a precious gem. Tall windows and low-level furnishings fill the space with natural light and showcase the stunning city views just outside.

Blush-colored roses bloom on the opposite side of the space, creating a display that distracts from the sleek TV. A textured buffet below offers storage for DVDs and complements the room's metallic accessories.

For a truly polished look, architect Lauren Rubin continued those jewel tones into the open dining area. Here, four modern chairs with golden seats warm the white walls and create a luxe corner for entertaining.

Around the corner, large cabinets and wood floors comprise the galley kitchen. To help the narrow space feel more airy and open, architect Lauren Rubin introduced large windows, recessed lighting and all-white furnishings.
