This black agate was dug by our own team on the Nicomen Plateau near Boston Bar, British Columbia, where black agate nodules weather out of volcanic rock.

It forms when silica-rich groundwater seeps into gas pockets and cracks in volcanic rock long after the lava has cooled, depositing silica that slowly hardens into a dense, translucent stone. At 6.5 to 7 on the Mohs scale, agate is tough enough for everyday jewelry.\u003c\/p\u003e\n\u003cp\u003eIn crystal traditions, agate is often associated with balance, calm and steadiness. These associations come from spiritual and folk traditions rather than scientifically established properties.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChemical Composition:\u003c\/strong\u003e Chalcedony (microcrystalline quartz), SiO₂\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMohs Hardness:\u003c\/strong\u003e 6.5 - 7\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e Natural\/None\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1pc\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWith this product, you will receive the exact stone shown in the photograph.
