Its deep black background, streaked with silver-grey crystals and bluish reflections, makes it one of the rare northern granites that combines strong visual character with real performance in Quebec's climate. No artificial primers: each slab is unique, stable, and designed to last decades without aesthetic compromise.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhere does Cambrian Black's aesthetic come from?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCambrian Black is extracted from the Canadian Shield, one of the oldest geological formations on the planet. Its dense black color comes from a high concentration of biotite and hornblende, two minerals that give it both its depth and its exceptional hardness. The antique finish reveals feldspar crystals that capture light without glare: a rare balance between visual richness and discretion. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy choose Cambrian Black over imported granite or black quartz?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eTraceable and local origin — extracted in Quebec by Polycor, Cambrian Black offers a significantly reduced carbon footprint compared to granites imported from India or Brazil, with provenance documentation available upon request.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eSuperior natural hardness — with a Mohs hardness rating of 6 to 7, it resists everyday scratches without additional chemical treatment.
