Dyed Black Agate is a natural agate that has been color-enhanced to achieve a deep, uniform black appearance. The base material is chalcedony (a variety of quartz), often treated to highlight its structure and improve color consistency.
With a hardness of 6.5–7 on the Mohs scale, it is durable and suitable for jewelry and decorative use. The polished finish gives it a smooth, glossy surface.
Each piece may show subtle banding and natural variations, making every stone unique.
