Embark on an exciting journey to discover the beauty and wonder of coral! These unique and captivating organic gems have captured the imagination of rock hounds and collectors for centuries. In this article, we’ll explore the history, identification, characteristics, and tips for hunting and collecting coral specimens.
History & Origin of Coral
Coral has a rich and fascinating history, dating back to ancient times. Highly valued for its beauty and rarity, coral has been used in jewelry, art, and religious objects throughout various cultures. The name “coral” is derived from the Greek word “korallion,” which likely has its roots in the Hebrew word “goral,” meaning small pebble or stone.
Historically, coral has held significant cultural and spiritual importance in many societies. In ancient Egypt, it was believed to protect against evil spirits and provide strength to the wearer. The Romans and Greeks also valued coral, associating it with protection, luck, and wisdom. In Native American cultures, coral was often used in combination with turquoise and silver to create stunning jewelry and ceremonial objects.
Coral Identification & Physical Properties
To identify and appreciate the unique characteristics of coral, it’s essential to understand its physical properties. The following table provides an overview of coral’s key attributes:
| Physical Property | Description |
|---|---|
| Chemical Composition | CaCO3 (calcium carbonate) |
| Formation | Formed by marine organisms called coral polyps, which secrete calcium carbonate to create a hard skeleton |
| Luster | Vitreous to waxy, often polished to enhance appearance |
| Transparency | Opaque to translucent |
| Fracture | Conchoidal to splintery |
Coral Colors
Coral exhibits a diverse range of colors, including red, pink, white, blue, black, and orange. The most highly sought-after color is a vibrant red, known as “oxblood” coral. Coloration in coral is primarily influenced by the presence of pigments and the type of algae that live symbiotically within the coral polyps.
Coral Hardness
Coral has a relatively low hardness, ranging from 3 to 4 on the Mohs scale. This makes it a relatively soft material, which can be easily scratched or damaged if not handled with care. Coral’s hardness can vary depending on its composition and the specific type of coral.
Coral Types
Red Coral (Corallium rubrum)
Red coral, also known as precious coral or Mediterranean coral, is highly prized for its vibrant red and pink hues. It is primarily found in the Mediterranean Sea and is considered the most valuable variety of coral.
Black Coral (Antipatharia)
Black coral is a deep-sea coral known for its black, brown, or dark green color and unique, tree-like branching structure. It is often used in jewelry and has been designated as the official state gem of Hawaii.
Blue Coral (Heliopora coerulea)
Blue coral is a rare and beautiful variety known for its distinct blue color. It is formed by a unique species of coral polyps that secrete a blue-colored skeleton, which is later polished to bring out its vibrant hue.
White Coral (Balanophyllia elegans)
White coral, also known as ivory coral or angel skin coral, features a creamy white to pale pink color. It is often used in jewelry and carved into intricate shapes and designs.
Coral Uses
Coral has been used for various purposes throughout history, including:
- Jewelry: Coral’s natural beauty and vibrant colors make it a popular choice for rings, necklaces, earrings, and bracelets.
- Carvings: Coral’s softness allows it to be carved into intricate shapes and designs, making it a popular material for decorative objects and religious artifacts.
- Aquarium decorations: Natural or artificial coral is often used tocreate visually appealing and realistic environments in marine aquariums.
- Medicine: In some traditional cultures, coral has been used as a remedy for various ailments, such as digestive issues and skin conditions.
How Much Is Coral Worth?
The value of coral can vary significantly depending on factors such as color, rarity, size, and overall quality. Price ranges can be anywhere from a few dollars for small, lower-quality pieces, to several thousand dollars for large, high-quality specimens, especially those in the highly coveted oxblood red color. It’s important to note that the trade of certain coral varieties, such as red and black coral, is regulated to protect these species from over-harvesting. Always ensure that any coral you purchase has been sourced ethically and legally.
