Hey sisters and jade friends! 👋 I'm your old friend, who has been in the jadeite industry for over ten years. Today, I want to talk about a particularly interesting jade stone – Bi Yu (碧玉, Nephrite Jade). Many people, when they hear Bi Yu, might first think of Russian Bi Yu, but in fact, there are far more varieties of Bi Yu than just that! Today, I'm going to delve into the 'past and present' of Bi Yu and help you go from a novice to an expert! ✨

What Exactly is Bi Yu? 🤔

First, we need to clarify that Bi Yu is actually an important category of Hetian Jade, primarily composed of tremolite. Its colors range from spinach green, apple green to duck egg green, and some even have black spots, offering a rich variety of hues. Don't be fooled by the 'Bi' (green) in its name into thinking it's related to jadeite; they are completely different minerals! Jadeite is a pyroxene mineral, while Bi Yu is an amphibole mineral. This is a crucial point to remember! 📝

The 'Four Heavenly Kings' of Bi Yu 👑: A Deep Dive into Varieties!

Common Bi Yu varieties on the market mainly come from the following origins, each with its unique 'temperament':

  • Russian Bi Yu (E Bi): Without a doubt, this is currently the most mainstream and popular Bi Yu variety on the market. Its characteristics are vibrant color and good oiliness, especially the 'spinach green' and 'apple green' shades of E Bi, which are simply the 'Hermès' of Bi Yu! 😍 E Bi material is usually fine and compact in structure, and when lit, it often exhibits a 'cat's eye effect' or 'sugar heart' structure. However, it's also common for E Bi to have black spots, which are its natural characteristic, not a flaw, and can even prove its natural origin. In my personal experience, a good E Bi should have uniform color, sufficient oiliness, and naturally distributed black spots that are not too dense to affect aesthetics.


  • Canadian Bi Yu (Jia Bi): Jia Bi has a very large output, with colors predominantly deep green, some even leaning towards dark green. Its characteristic is a relatively rugged texture and generally less oiliness compared to E Bi, but it excels in large sizes, often used for large ornaments or bracelets. Jia Bi also has good translucency, appearing quite transparent when lit. I've seen some very high-quality Jia Bi bracelets with deep colors that exude a strong presence when worn, and their prices are relatively affordable, making them a good choice for entry-level Bi Yu.


  • Xinjiang Manasi Bi Yu (Manasi Bi Yu): This is a domestic Chinese Bi Yu with a long history. Manasi Bi Yu's color is usually deep, predominantly dark green, often with irregular black spots. Its characteristic is a relatively hard texture and high density, but its oiliness is not as good as E Bi. In recent years, high-quality Manasi Bi Yu has become increasingly rare, and its price is gradually rising. I once had the good fortune to collect a Qing Dynasty Manasi Bi Yu thumb ring; the historical weight and unique dark green color still make me cherish it.


  • Qinghai Bi Yu: Qinghai Bi Yu is a variety that has only gradually gained market recognition in recent years. Its color is usually lighter, predominantly light green or grayish-green, with a relatively fine texture but average oiliness. A characteristic of Qinghai Bi Yu is the frequent presence of white or gray 'stiff' spots, which are its natural features. Although its current market value is not as high as E Bi, with decreasing mining volumes and increasing public awareness of Bi Yu, it also has certain appreciation potential in the future.


How to Spot Good Bi Yu at a Glance? My Exclusive Secret! 🕵️‍♀️

  • Look at the Color: Color is the most intuitive criterion for evaluating Bi Yu. High-quality Bi Yu should have a vibrant, uniform, and lively color. Spinach green and apple green are superior, followed by duck egg green. Avoid colors that are grayish, dull, or overly uneven.

  • Look at the Oiliness: The oiliness of Bi Yu is an important indicator of its value. Good Bi Yu feels warm and smooth to the touch, and visually appears lustrous and oily. If it looks dry and dull, it's likely not good material.

  • Look at the Structure: Use a strong flashlight to illuminate and observe the internal structure of the Bi Yu. High-quality Bi Yu should have a fine, compact structure with no obvious granular feeling. The 'cat's eye effect' or 'sugar heart' structure often found in E Bi is a bonus. If the structure is coarse, with obvious cotton-like inclusions or cracks, be cautious.

  • Look at the Black Spots: It's normal for Bi Yu to have black spots, but pay attention to their distribution and size. Black spots should be natural and evenly distributed, not too dense or forming large black patches that affect the overall aesthetics.

  • Look at the Craftsmanship: Carving is also an important factor influencing the value of Bi Yu. Good carving can imbue Bi Yu with vitality and enhance its artistic value. Choose pieces with exquisite carving, smooth lines, and auspicious meanings.
