I KNEW SEA WASHED CORALS BUT WHEN I SAW IT AS A FOSSIL FIRST TIME I WAS BLOWN AWAY !THIS IS A GENUINE CHRYSANTHEMUM FOSSIL CORAL SET IN 925 SILVER THAT I HAVE TEXTURED USING A SEA WASHED CORAL THAT I FOUND WALKING IN A BEACH. SO THE PATTERN ON THE SILVER MIRRORS THE PATTERN OF THE STONE ALSO ADD A FEW LEAVES MANIFESTING A BEAUTIFUL UNIQUE HANDMADE HARMONIZED PENDANT. ITS 8 cm LONG x 5 cm WIDE AND COMES WITH A SILVER CHAIN 45 CM
Fossil coral is a natural stone that is formed when ancient coral is gradually replaced with agate. The proper name for this material is agatized coral or agatized fossil coral. The fossilized coral typically appears as small flower-like patterns in the stone.
They may vary widely within a single stone depending on weathering and oxidation and the original mineral content.
Corals are among the most colorful animals in the sea. Most corals live in warm, shallow, tropical seas and feed on plankton. The oldest fossil corals are from the Ordovican period, over 450 million years ago. Corals are marine animals with a sac-like body, mouth, tentacles and skeleton. It is the skeleton that survives in the fossil record. Corals may be solitary or found in large colonies.
It is important that people understand “fossil coral” is a natural stone formed from ancient corals. It should not be mistaken for protected and endangered coral reef from the modern oceans of today. Of the varieties of fossilized corals found throughout the geologic record, exquisitely detailed specimens from the mountains of Indonesia are most unique and beautiful. Corals have been growing in the oceans around the world for almost 500 million years. The corals thrived in warm shallow marine waters and over time were buried in sediments as the land surface was juggled by crustal plate movements or the oceans rose and fell. Temperature and pressure from compaction during burial, resulted in those deposits, in time, becoming rock and part of the present day geological record. Decorative coraline limestone and marble are popular building materials and have been used for centuries.For many years, ancient coral deposits have been mined for their high quality calcium, potassium, magnesium and sodium content which is used in health supplements. Fossil coral has also been used in fertilizers. Fossil coral has even been used in filters to remove impurities such as chlorine and formaldehyde from water.
In some cases corals were buried in sediment as the land surface was affected by crustal plate movements or the oceans rose and fell. Temperature and pressure from compaction during burial resulted in those deposits becoming rock and part of the present day geological record.
