Agate is a grounding stone that brings the emotional, physical and mental into balance. Being grounded means we're well connected with the earth. That helps us remain calm, rational and make better decisions especially when surrounded by chaos. This Heart shaped piece of Natural Agate measures 4.5cm x 3.3cm approx and is suspended from a 20 Inch 925 Silver chain. Agate was the traditional birthstone for May back in the days of the ancient Romans and Greeks, when birthstones were generally assigned to the astrological sign rather than the month. Agates are a form of chalcedony, available in almost any colour, and often banded, striped or spotted.
