Taj Mahal and Crystal White Supreme come out of the same broader quartzite family but sit at opposite ends of the temperature spectrum. Taj Mahal is the warm ivory benchmark — cream, beige, a soft inner glow. Crystal White Supreme is the cool, bright version — true white field, denser crystalline structure, more reflective in daylight. Same hardness; different mood.

On a kitchen island in a warm walnut palette, Taj Mahal disappears into the room as a quiet neutral. In a cool white-and-plaster bath with rift oak and brushed nickel, Crystal White Supreme reads cleaner and brighter than any Taj cut. Choosing between them is usually a question of how warm the rest of the scheme already runs.

Both come through Royal Stone in honed and leathered, in 2cm and 3cm. Walk both side by side in the yard if you're undecided — under daylight, the difference reads instantly, and selecting from photographs gets it wrong more often than not.
