Introduction of red coral
Red corals grow in the ocean, often resembling branches and flowers, which led people to mistakenly believe they were marine plants for a long time. It wasn't until the 1920s that scientists recognized corals as coelenterates—organisms that secrete calcium carbonate skeletons. With an incredible diversity of species, corals vary greatly in quality, and red coral is one of the eight-shot corals, known for its vibrant color and radiant texture.
As an organic gemstone, red coral is cultivated deep underwater, typically between 100 to 2000 meters below the surface. It is considered one of the three organic gems alongside pearls and amber, and it also holds a sacred place in Eastern Buddhist texts as one of the seven treasures. Historically, red coral has been seen as a symbol of wealth and good fortune. Naturally formed by polyps, it grows very slowly and cannot regenerate, making it extremely rare. Red coral is found only in three major straits: the Taiwan Strait, the Japanese Strait, and the Baltic Strait, further limiting its availability.
Due to its scarcity and beauty, red coral has become highly sought after, especially among collectors. Fine specimens have seen a rapid increase in value over recent years. The word "coral" comes from the Latin "corallium," and the ancient Romans believed it had protective properties, such as preventing disasters, enhancing wisdom, stopping bleeding, and promoting warmth.
In ancient China, red coral was seen as a symbol of happiness and nobility, often referred to as "Ruibao." It was used in high-ranking officials' ceremonial caps during the Qing Dynasty and in Tibetan lamas’ prayer beads. In India, it's called the "mother of the earth," while the Japanese emperor regarded it as his most precious treasure. Across cultures, red coral has always held a special status.
Today, natural red coral jewelry is highly popular, with pieces like large coral trees over two feet tall becoming increasingly rare. As awareness of its value grows, so does its collectibility. Due to its non-renewable nature and limited supply, red coral remains a prized possession.
Coral species include several types similar to red coral, all belonging to the eight-shot group. They share a soft body structure and contain horny bones, with colors ranging from deep red and pink to orange, white, and even milky yellow. These corals live at depths between 100 and 4,000 meters, found in tropical and subtropical regions worldwide, including Japan, the Philippines, and the South China Sea.
In the industry, red coral is categorized into different color grades:
- **AKA**: Dark red or deep red, the most valuable, mainly from Japan and Taiwan.
- **Sardine**: Bright red, commonly found in Italy.
- **MOMO**: Pink or orange-red.
- **Angel Skin**: Soft pink, often called "child face" or "angel’s skin."
- **White**: Pure white coral.
Beyond its aesthetic appeal, red coral has been used in traditional medicine for its healing properties, believed to calm shocks, clear the mind, and treat conditions like epilepsy and keratitis. Modern medicine also explores its potential in bone regeneration and ulcer treatment.
Whether worn as jewelry or admired for its cultural significance, red coral continues to captivate and inspire. Its beauty, rarity, and historical importance make it a true treasure of the sea.
