Did you know Crystal Grey Quartzite started out as sandstone? 💭

Millions of years of heat and pressure turned this rock into Crystal Grey Quartzite, which is why no two slabs are ever alike. That same process gives each block its own unique gray, crystalline veining, and it's also what makes this one of the toughest natural stones for a kitchen. ✨

Bold, ink black veining flows across a pure white canvas in Calacatta Panda quartz, a pattern where no two slabs ever repeat quite the same. ✨

From that same striking veining comes this island countertop, becoming the true centerpiece of the room and a standout from every angle. 🤗
