Framed pair of fir cones cut and polished from Patagonia. Showcasing particularly nice contrast of colours from beige-greys to soft pink-reds, separating the core and seeds where the fossilisation process has materialised over millions of years. Finished with a white frame mahogany border mount.
Petrification involves replacement of the tissue within the Fir cone, which is replaced by surrounding solutions, usually silica or calcium carbonate. The crystallisation of silica is a combination pressure & heat, resulting a crystal transition. It is often impossible to attribute silicified or similarly preserved woods to particular plants or trees. Usually a softwood which explains the attractive colours these fossilised Fir cones produce from the Araucaria family, commonly the Ginkgo and Monkey Puzzle tree.
