Again a good sized cabachon packed with small honey coloured calcite ammonites (Promicroceras planicosta). The cabachon has been hand worked by a professional lapidarist and has a high shine which really brings out all the tiny details. A wonderful piece for jewellery. Approximately 200 million years old.
This beautifully hand crafted cabachon is a very large size and would make a wonderful addition incorporated into a piece of jewellery. This iconic fauna is approximately 200 million years old, in which billions of these small ammonites (Promicroceras planicosta) met their sudden demise, either through volcanic activity from the Mendips or a poisonous algal bloom. A totally unique piece. This cabachon is GRADE A material.
A beautifully preserved example which is complete and has an immaculate centre. This is an uncommon ammonite in the oolite of the south coast. An important addition for the collector of rare UK oolithic ammonites. Approximately 167 million years old.
