A guide to buying jadeite

When jade experts talk about jade, they often mention the word "bottom", which leaves laymen confused. What is the “bottom” of jadeite? The "bottom" of jadeite is also called the "ground" or "ground". "Bottom" is the human eye's intuitive feeling of the appearance and interior of jade jewelry, and it is also an indicator for comprehensively evaluating the quality of jade.

Among the many indicators for evaluating jade quality, such as color, texture, transparency, base, craftsmanship and weight, the most visible but intangible one is the "base". "Bottom" refers to the characteristic of the light green base part other than green. It is a comprehensive reflection of the jade's texture (type), transparency (water), gloss, clarity and light color tone.

The "bottom" is more of an aesthetic indicator, so the evaluation of the quality of the "bottom" is not quantifiable. The base color is a color other than emerald. When jade is colorless, the "base" is a comprehensive reflection of its type, water, gloss and clarity. When jade is full green or full color (orange, yellow, black, etc.), the color and the base are integrated. At this time, the "base" is a comprehensive reflection of its type, water, color, gloss and clarity.

It can be seen that the "base" of jade includes two key elements and three general factors. The two key elements are texture (type) and transparency (water), and the three general factors are gloss, basic color and clarity of jade. Therefore, when evaluating the quality of the "base" of a finished or semi-finished jade product, the main thing to look at is the effect of the mutual reflection between the jade, the type and the water.

After processing, the surface of the clean and delicate jadeite is very smooth. It is transparent and moist under the light, which can fully reflect the charm and aura of the jadeite. Business people in the jade industry call this phenomenon "full of precious energy."

The quality of the "bottom" is directly related to the processing quality and ornamental effect of jadeite materials, and affects the quality grade and commercial value of jadeite pieces.

Many people confuse the concepts of "type" and "base" when buying jade. In fact, there is an essential difference between the two. The first one focuses on the microscopic indicators of the internal structure of jade, while the bottom one focuses on the external, macroscopic overall feeling. Generally speaking, poor quality leads to poor base, but good quality does not necessarily lead to a good base.

Therefore, when players choose finished jade products, they should not only look at the type, but also the bottom, the quality of the color, whether the jade is clean and not dirty, and whether there are any lines or cracks.

Currently, the domestic jade market is in a stage of steady development, and the quality varies greatly. There are jade bracelets worth millions, as well as jade handicraft gifts worth tens of yuan. Generally speaking, the investment value of ordinary jade is not high, and only high-end jade has greater room for appreciation. However, collection-level jade is very rare. How to select collections from the dazzling array of jade requires money and time.

When choosing jadeite, you should first choose transparent or nearly transparent jade, which experts call "old jade" and has the highest value; translucent jade is called "new old jade" and is the second most valuable; opaque and dry jade is called "new jade" and is less valuable. Among all jades, green jade is the most precious, followed by purple. In 2003, a full purple bracelet only cost tens of thousands of yuan, but today, a full purple bracelet of the same quality can cost up to one million yuan.

Top quality jadeite is called jadeite. Color, transparency, uniformity, shape and sound are the ways people generally appreciate or evaluate jade. Jade is divided into: glass type, ice type, ice glutinous type, dark old pit, old pit, gold wire, oil clear, bean green, flower green, melon green, etc. Among them, ice-type jade is the best quality, and the one with extremely high water content and good transparency is called "glass type", which can be said to be a treasure among "ice types".

1. Green of jadeite: the greener it is, the more valuable it is.

2. The red of jadeite: Jadeite is red, emerald is green, the brighter the red, the more expensive it is.

3. Color: Green and red are the best colors of jadeite, followed by yellow and purple. The brighter the color, the more expensive it is.

4. Transparency: Jadeite with tight internal crystal structure has better texture and higher transparency. What we call "glass type" is this kind of jadeite with high transparency. If the jade itself is rich in chromium, it becomes ice type jadeite, which is very valuable and hard to find.

5. Uniform color: In addition to the delicate green color and high transparency, the tone must also be uniform to be a top quality product.

6. Defects: Pay attention to whether there are cracks, spots, etc. These defects will affect the quality of jadeite.

7. Shape: Most jade ring faces are oval egg-shaped, but there are many other shapes. The quality and beauty of the shape also affects the price of the jade.

8. Carving: The quality of the craftsmanship and symbolic meaning of a carved ornament will affect its price.

9. Size and thickness: Jade of the same quality will of course have a higher price if it is larger and thicker.

10. Gloss: In addition to the above conditions, the gloss must be bright and not dull.
