UV Reactive Opalized Ammonite Matched Pair, 4" Fossil Set Beautiful matched Ammonite pair with intricate spiral chambers, warm brown and reddish tones, and beautiful natural mineral detail throughout. The outer shell has an opalized appearance with subtle iridescence, adding another layer of color and dimension to these fossils. The combination of the matched halves, fossil structure, opalized outer shell and UV reaction makes this a particularly fun piece for both fossil and UV-mineral collectors. Ammonites are traditionally associated with cycles, transformation, growth, evolution and moving through life's changes. Their spiral form is often viewed symbolically as a reminder of continual growth and the cycles of nature. A great choice for fossil collectors, geology lovers, UV-reactive mineral collectors, or someone looking for an unusual matched display piece.
