TraOnyx is the commercial name for the small family of stones that sit between travertine and onyx — calcareous bodies with the linear bedding of travertine and the partial translucency of onyx. Synergy Rainbow Creme is the warm end of that family: a cream-to-pale-taupe field crossed by fine horizontal banding in soft caramel and oxidized rose, with the occasional translucent pocket where the stone reads as true onyx.

Leathered. The leather finish reads almost matte while still catching enough light to hint at the translucency underneath — the right finish for a project that wants the warmth and depth of onyx without the high-gloss formality of a polish. Cut at roughly 71" × 113", the slab is sized for fireplace surrounds, bar tops, powder vanities, or full-height bath wall cladding.

TraOnyx is softer than quartzite and harder than typical onyx — usable on light-duty horizontals as well as walls. On the floor in Los Angeles.
