Antolini Platinum Black Label Stratos — Stratos Finish, in Los Angeles

Antolini Platinum · Stratos

The Plumber’s Stratos.

Quarried in Tivoli, Italy, and finished Stratos through the Antolini Platinum program.

The Antolini Platinum Stratos takes classical Tivoli vein-cut travertine and runs it through the Antolini Stratos process — a finely textured finish that emphasizes the linear striations of the stone. Plumbers and fabricators have long favored Stratos for working kitchens and baths: the surface reads matte, the lines read architectural, and the finish forgives everyday etching.

At 69″ × 119″, the slab sizes for working kitchen islands, primary bath composition, and fireplace surrounds. The Stratos finish delivers the line discipline of a contemporary architecture practice while keeping all the classical warmth of Pink Tivoli. Paired with blackened steel, oak, or terracotta, the slab reads as the room.

The right travertine when the brief is classical with working-friendly finish. Pair with blackened steel, terracotta, oak millwork, lime plaster, and a quieter marble or limestone elsewhere as counterpoint.

One Finish · Stratos

Stratos,
to keep the lines legible.

Antolini Platinum ships at the Stratos register. The Stratos process amplifies the linear striations of the travertine and keeps the surface contemporary, matte, and working-friendly.

The right surface for working kitchens, primary baths, fireplace surrounds, and any application where the slab is meant to live as architecture.

Stratos travertine, finely textured, matte

Stratos keeps the Platinum striations legible and the slab contemporary. The slab sits calmly against blackened steel, plaster, and oak — and any patina that develops with use reads as part of the lines rather than wear.

Common Questions

Questions,answered.

What is Antolini Platinum Stratos Travertine?
Platinum Stratos takes the Antolini Black Label Platinum cut of Tivoli vein-cut travertine and runs it through the Antolini Stratos finishing process — a finely textured finish that emphasizes the linear striations of the stone. The result is the most respected working-friendly finish on classical Italian travertine.
Is Stratos travertine good for kitchen countertops?
Yes — Stratos is the fabricator-favorite finish for working kitchens. The finely textured surface hides the small etching that develops with use on travertine, and the striations run consistent under everyday wear. Plumbers and stone yards have used Stratos on working kitchens for years.
Where does Platinum Stratos work best?
In the room where the brief is classical with working-friendly finish. A working kitchen island, a primary bath composition, a fireplace surround, a full-height feature wall, a dining table. Pair with blackened steel, terracotta, oak millwork, lime plaster, a quieter marble or limestone elsewhere as counterpoint.
Is Stratos available honed or leathered?
Both by special order. The slab ships at Stratos, calibrated to bring out the linear striations. Honed quiets the lines; leather brings them out softly. Bring drawings and we will lay the options.
How is Stratos different from leathered or honed Platinum?
Same slab family, three different finishes. Stratos amplifies the striations and reads as architecture. Leathered softens the slab with subtle texture. Honed brings the field to a clean matte. Pick the finish that fits the room.
How do I see Platinum Stratos in person?
Royal Stone is at 2303 South Sepulveda Boulevard, West Los Angeles. Designers and private clients are welcome by appointment Monday through Friday. Call (310) 477-3223 and we will pull the slab for you.

Walk Platinum Stratos,
by hand.

Stratos is meant to be felt. The slab behaves as material up close. We’d rather pull the slab and walk you through than describe it.
