"Spider web black fossil coral" is agatized fossil coral (a type of gemstone, not true coral) that exhibits a black color with white or gray intricate patterns resembling a spider web. It is valued for its unique aesthetic and perceived metaphysical benefits.
Origin and Formation
Spider web black fossil coral is not a type of living coral, but rather an ancient fossil where the original coral skeleton has been replaced over millions of years by minerals, primarily agate (a form of chalcedony). This process, called agatization, preserves the intricate skeletal structure of the coral as a durable, stone-like material.
Locations: Most high-quality commercial fossil coral specimens are found in specific locations, including Indonesia, and in the United States in Florida and Georgia. Florida even designated fossil coral as its official state rock.
Ethical Note: The term "black coral" can also refer to a different species (order Antipatharia) that is a living, deep-sea animal, the trade of which is heavily regulated and often illegal without specific authorization (CITES Appendix II). The material used in jewelry as "black fossil coral" is typically the agatized fossilized stone, not the protected organic black coral harvested from the sea.
Jeweler Uses
Jewelers prize spider web black fossil coral for its unique, natural patterns that add depth and a sense of earth history to a piece.
Jewelry Types: It is commonly used to craft a variety of items, including beads for necklaces and bracelets, earrings, and statement rings.
Cutting and Polishing: Due to its hardness (6.5 to 7 on the Mohs scale), it is durable enough for everyday wear. It is typically cut into cabochons (smooth, polished, dome-shaped gemstones) or polished as beads to highlight its patterns.
Design: Its distinct patterns make each piece one-of-a-kind and a popular choice for unique, natural, or bohemian-style jewelry. It is often paired with other gemstones or metals like silver and gold.
