Portoro Gold Tempest is a dramatic reinterpretation of the classic Portoro family. Instead of the tight black-and-gold banding the name traditionally calls to mind, this cut reads like weather — billowing slate and charcoal clouds shot through with wide rivers of molten gold and ochre, threaded with fine white quartz veining. It's a slab that wants to be seen at full height.
Polished to a high gloss, the surface deepens the gray field, lacquers the gold passages into something closer to amber, and makes the white veining read as bright filament. The pattern is large-scale and directional — it earns a feature wall, a long island, or a single-piece fireplace surround far more than a chopped-up application.
“Polished to a high gloss, the surface deepens the gray field, lacquers the gold passages into something closer to amber, and makes the white veining read as bright filament.”
Polished marble, 78" × 126" — fresh on the floor at Royal Stone. Also available leathered (see installed shot below), which mutes the gloss, deepens the gray field, and gives the gold passages a drier, more tactile read — a strong option when the polished version feels too much. Calcareous and acid-reactive; best specified for vertical features, vanities, fireplaces, and lower-traffic surfaces. Walk the yard to see the movement in person before committing to a layout.
In a completed kitchen at 8671 Clifton Way, Beverly Hills, CA 90211, Ryan Saghian Design carries Portoro Gold Tempest across the island, perimeter counters, backsplash, and range wall. The gray field settles into the light oak cabinetry while the gold movement picks up the brass fixtures.
