While walking through the geology section of the Museum Africa in Newtown, Johannesburg, I discovered these beauties. Agates are made up of layers of chalcedony, a type of quartz and are formed in rounded spaces in lava rocks called geodes. Playing around with the white balance and the ISO settings and not using a flash indoors was really exciting and a worthwhile experiment.
I'm definitely going back to discover more hidden treasures soon.
