Jade has long been cherished across various cultures for its beauty and symbolism.

However, there's often confusion surrounding the term "jade," as it encompasses two distinct minerals: jadeite and nephrite.

This article delves into the differences between these two gemstones, their individual values, and addresses common questions to help you make informed decisions when considering jade pieces.

Understanding Jade: The Two Varieties

The term "jade" refers to two different minerals: jadeite and nephrite.

While they share similarities, they differ in composition, appearance, and value.

  • Jadeite: A sodium and aluminium-rich pyroxene mineral, jadeite is renowned for its vibrant colours, including the highly sought-after "imperial green."
  • It also appears in shades of lavender, red, orange, yellow, and even blue.
  • Jadeite's texture is typically granular, and it has a hardness of 6.5 to 7 on the Mohs scale.
  • Nephrite: Composed of calcium, magnesium, and iron-rich amphibole minerals, nephrite is usually found in creamy whites ("mutton fat" jade) and various green hues, often with a more muted, fibrous appearance.
  • Nephrite is slightly softer than jadeite, rating between 6 and 6.5 on the Mohs scale, but is known for its exceptional toughness.

Distinguishing Between Jadeite and Nephrite

Several factors differentiate jadeite from nephrite:

  • Colour and Transparency: Jadeite boasts a broader spectrum of vivid colours and is often more translucent than nephrite, which typically presents in darker, more opaque tones.
  • Texture: Jadeite has a fine-grained, granular texture, whereas nephrite exhibits a fibrous, interwoven structure, contributing to its renowned toughness.
  • Geographical Sources: Jadeite is primarily sourced from Myanmar, while nephrite is found in locations such as China, New Zealand, Canada, and Russia.

Assessing Value: Is Jadeite More Valuable Than Nephrite?

In general, jadeite is considered more valuable than nephrite, primarily due to its rarity and the intensity of its colours.

The most prized jadeite, known as "imperial jade," features a deep emerald-green hue and high translucency, commanding premium prices in the market.

Nephrite, while historically significant and valued, is more abundant and typically less expensive.

However, exceptional nephrite pieces, especially those with historical provenance or superior craftsmanship, can also fetch high prices.

Cultural Significance and Symbolism

Both jadeite and nephrite hold profound cultural importance:

  • In Chinese Culture: Jade has been revered for thousands of years, symbolising purity, moral integrity, and immortality.
  • Emperors and nobility often adorned themselves with jadeite ornaments, considering them embodiments of virtue and status.
  • In Māori Tradition: Nephrite, known as "pounamu" or "greenstone," is treasured by the Māori people of New Zealand.
  • It is used to craft heirloom pendants and weapons, symbolising strength, authority, and a connection to ancestors.

Identifying Authentic Jade

To ensure the authenticity of jade:

  • Visual Inspection: Genuine jade often has a smooth, even texture without air bubbles. Be cautious of overly vibrant colours, as they may indicate dye treatments.
  • Temperature Test: Authentic jade feels cool to the touch and warms slowly when held.
  • Sound Test: When gently tapped, real jade produces a resonant, bell-like sound.
  • Professional Assessment: For significant purchases, it's advisable to seek evaluation from a certified gemologist or obtain a laboratory report to confirm authenticity and detect any treatments.
