The Fascinating World of Jade
Jade, one of the most revered gemstones throughout history, is renowned both for its ethereal beauty and its deep cultural significance. In this article, we will explore the various facets of jade, from its composition to its history, varieties, and much more.
Physical and Chemical Properties of Jade
What is Jade?
The term "jade" generally refers to two distinct minerals: jadeite and nephrite. Both are silicates, but they differ in composition and crystal structure. Jadeite is a silicate of sodium and aluminium, while nephrite is a silicate of calcium and magnesium. These differences influence their physical properties and appearance.
Detailed Characteristics of Jadeite and Nephrite
- Hardness: Between 6.5 and 7 on the Mohs scale.
- Colour: Displays a wide range of colours, including green (from very pale to intense emerald green), blue, lavender, pink, and white. The intense green, often called "imperial jade", is particularly valued.
- Crystal Habit: Generally forms in granular or fibrous crystals, giving it a dense and compact structure. This structure results in greater translucency and exceptional lustre.
- Translucency: Varies from semi-transparent to opaque.
- Hardness: Between 6 and 6.5 on the Mohs scale.
- Colour: Commonly found in shades of green, but can range from creamy white to dark green. The colours are generally more subdued compared to jadeite.
- Crystal Habit: Comprises interlocking fibres at the microscopic level, which gives it extraordinary toughness, making it extremely resistant to breaking and impacts.
- Translucency: Mainly opaque, with a more waxy appearance and less lustre than jadeite.
These differences mean that jadeite is often more valued for its translucency and variety of vibrant colours, while nephrite is appreciated for its exceptional strength and toughness. Each type of jade has its own beauty and unique features that make them desirable for different applications, from jewellery to works of art.
Jade is primarily found in Myanmar (Burma), where the highest quality jadeite is mined. Other significant deposits include Guatemala (nephrite), New Zealand (nephrite), and Russia (nephrite). The quality of jade varies depending on its origin, influencing its value and appearance.
Etymology and History of Jade
Origin of the Name "Jade"
The word "jade" comes from the Spanish term "piedra de ijada", historically used to describe its use in treating kidney ailments. This terminology reflects the high esteem that ancient Mesoamericans held for this gem, valuing it as a "stone of the flank" for its supposed healing properties.
Origin of the Name "Nephrite"
The term "nephrite" comes from the Greek "nephros", meaning "kidney". This name is also due to the ancient belief that this stone had the ability to cure kidney diseases and related ailments. Its use in this sense reflects the historical connection of nephrite with medicine and healing, similar to the beliefs associated with jadeite.
Cultural History and Legends of Jade
Among the Maya and Aztecs, jade was extremely valued, often more so than gold. The Maya regarded jade as a symbol of life and fertility, and used it in religious rituals and as funerary offerings for the nobility. They believed that jade could open the path to the underworld and connect with the gods. On the other hand, in Aztec culture, jade symbolised water and vegetation, being central in rituals seeking to ensure rains and good harvests.
In China, jade is known as "yu" and has been valued for millennia, being considered a symbol of purity, morality, and authority. It was believed that jade had life-prolonging properties, and it was common to see it in ritual objects and imperial adornments. Additionally, jade figures were placed in the mouths of the deceased, as part of a ritual to ensure immortality.
Jade and Buddhism
In Buddhism, jade is highly revered, especially in China and other East Asian countries. It is associated with virtue and morality, being a symbol of the Buddhist principles of compassion and wisdom. Statues of Buddha and other religious icons are often carved in jade, reflecting its sacred status and connection to spiritual enlightenment.
While jade was not common in ancient Greece, its name, "nephrite", reflects Greek influence in its medicinal perception. The Greeks believed in the healing properties of certain stones, and this belief extended to jade when it reached Europe through trade routes.
Pounamu and the Legend of Taniwha Poutini (Jade in New Zealand)
Pounamu, also known as New Zealand greenstone, holds a special place in Maori culture and traditions. This stone is known not only for its beauty and durability but also for its deep cultural significance. One of the most famous legends associated with Pounamu is that of Taniwha Poutini. According to this story, Poutini is a taniwha (a supernatural being in Maori mythology) that protects the people and lands of southern New Zealand. The legend tells that Poutini kidnapped Waitaiki, a beautiful married woman, and took her south. To escape from Waitaiki's husband, who was pursuing them, Poutini transformed the woman into jade and hid her in the waters of the Arahura River. This legend not only explains the origin of Pounamu but also connects it with themes of protection, love, and transformation. Pounamu is highly valued by the Maori and is used in the creation of tools, weapons, and jewellery. Moreover, it symbolises peace, harmony, and respect, and is considered a taonga (treasure). This stone is traditionally passed down from generation to generation, carrying with it stories, traditions, and the essence of the land and Maori culture.
These stories and legends underline the universal fascination with jade, revealing not only its beauty and rarity but also its profound significance in various cultures. From prestige and power in China to spiritual rituals in Mesoamerica, and its connection to enlightenment in Buddhism, jade remains a stone of great cultural and spiritual importance.
