Antolini Thunderflash Quartzite slab in matte finish lifted on the crane against blue sky, soft seafoam-green field crossed by rust-red lightning veining

Thunderflash is one of the more theatrical quartzites Antolini quarries from Brazil, and this new arrival is a clean read of the material at its best: a soft seafoam to jade-green field, lit from within by chalk-white quartz drift, then cut by sharp rust-red and oxblood veining that branches across the slab like a lightning strike. The name is literal — once you see the diagonal bolt that runs corner to corner on this slab, you understand the brand.

Antolini's matte finish suits Thunderflash. Polishing it would push the green toward glassy emerald and overstate the red; the matte hand keeps the surface mineral, almost watercolor, so the rust veining reads as drawn rather than painted. It is the right finish for a feature island, a vanity, a fireplace cladding panel, or a bar front where the slab is the room's color story.

From the slab arrival, 2024

Cut at 2cm and measuring 76" × 129", the slab carries enough length for a single-piece island top or a long full-height vertical panel. The container included consecutive blocks, so bookmatched butterflies can be specified on request.

On the floor in Los Angeles this week. Walk it before it is reserved.
