Agate is Known as nature’s banded beauty, agate’s mesmerizing patterns are instantly recognisable.

Origin&Supply of Agate

Agate is formed in cavities of volcanic rocks. It’s a variety of chalcedony, formed from layers of quartz which follow the cavity’s outline – this is what creates the striking banding. Agate measures 7 on the Moh's scale, meaning some varieties will be more prone to chips and cracks from daily wear than others.

The most well known ones are eye agate, which has ring-shaped bands with a pointed centre; and landscape agate which features moss like patterns.
