Agate is the obvious stone for autumn jewellery. It forms by filling a cavity in its host rock, known as a geode. The result is round nodules, with bands like the rings of a tree trunk, looking like eyes, often with crystals in the centre. Rock Crystal, Amethyst and Citrine are just a few crystals that are found in the centre of a geode.
The necklace shown is Botswana Agate which is always shades of browns.

Agate was highly valued as a talisman in ancient times and has been used as a traveler’s amulet for centuries. It’s believed to bring fortune, health, wealth and long life. Some call its strange patterns ‘cosmic caterpillar tracks’. Others’ swear that wearing these beads can heighten the spiritual consciousness and balance the body’s physical and mental states.
