Agatized Fossil Coral formed when the skeletons of prehistoric marine lifeforms on the ocean floor became fossilized through hardened deposits left by silica-rich waters (this is called “silicified”) in a process that took around 20-30 million years! Agate, a variety of chalcedony (microcrystalline quartz) slowly replaces the existing mineral while retaining its original form, a process referred to as a “pseudomorph”. Most agatized fossil coral exhibits a dull to waxy luster and interesting skeletal-like ancient coral patterns, often appearing in flower shapes.

Interestingly, fossil coral deposits are used for the making of health and drug supplements because of their high calcium, potassium, magnesium and sodium content. Agatized Fossil Coral is also the official state stone of Florida, USA. It is said that Native Americans in the Florida region traditionally utilized Agatized Fossil Coral to make tools and weapons.
