Hello everyone, I'm Old Wang. Having worked in auction houses for over two decades, I've handled countless pieces of jadeite. People often ask me why some antique jadeite, even after a century, remains as lustrous as new, while some newly acquired pieces dull within a few years. Beyond the quality of the material itself, the art of maintenance is key. Today, I'm going to share, without reservation, some practical jadeite maintenance tips I've gathered over the years.

Scenario Introduction:

I remember years ago, during a private negotiation, I saw a Qing Dynasty full-green old pit jadeite bangle. The bangle was dripping with emerald green, full of luster, as if water could be squeezed from it. What amazed me most was its surface sheen, that gentle radiance emanating from within, incomparable to new jade. The owner told me that this bangle was passed down from ancestors, and apart from wearing it, it hadn't undergone any special 'maintenance,' just daily 'playing' and 'cleaning.' At that moment, I realized that jadeite maintenance is not as complicated as imagined, but it requires meticulous patience and the correct methods.

Core Techniques: Jadeite's 'Three Fears and Three Joys' and Daily Care

  • 'Three Fears': Avoid High Temperatures, Strong Acids/Alkalis, and Hard Object Collisions

* Fear of High Temperatures: The internal structure of jadeite changes under high temperatures, leading to dehydration, loss of luster, and even 'cotton-like' phenomena. Therefore, remember not to expose jadeite to direct sunlight for extended periods, and certainly not to soak it in hot water or place it near fire sources. I once saw someone wearing a jadeite bangle while soaking in a hot spring; soon after, the bangle appeared dry and dull, which was a pity. When wearing it in summer, also avoid prolonged sun exposure.
* Fear of Strong Acids/Alkalis: Strong acids and alkalis can corrode the surface of jadeite, causing it to lose its original luster. In daily life, dish soap, soap, cosmetics, perfumes, etc., all contain varying degrees of chemical substances. When wearing jadeite, try to avoid contact with them. It's best to remove jadeite when showering, washing dishes, or doing housework. My experience is that after washing hands, if jadeite gets wet, simply wipe it gently with a clean, soft cotton cloth.
* Fear of Hard Object Collisions: Although jadeite has high hardness, its toughness is relatively poor. It's prone to cracks or even breakage when subjected to heavy impact or falls. I've seen too many cases of cracks caused by accidental bumps, some even drastically reducing their value. Therefore, when engaging in strenuous exercise or activities where collisions might occur, be sure to remove jadeite and store it properly. When storing, it's best to place it separately in a soft cloth bag or jewelry box to avoid friction with other hard objects.

  • 'Three Joys': Joy of Cleaning, Joy of Playing, Joy of Moisture

* Joy of Cleaning: The surface of jadeite easily absorbs dust and oil. Regular cleaning helps maintain its luster. The simplest and most effective method is to rinse it with clean water (preferably purified water), then gently wipe it with a soft cotton cloth or suede. For dirt in crevices, you can use a soft brush (like a baby toothbrush) dipped in water to gently brush. Remember, do not use any chemical cleaning agents.
* Joy of Playing: Jadeite is 'alive.' Frequent wearing and 'playing' with it allows the body's secreted oils and sweat to penetrate the jadeite's interior through its pores, making it more lustrous and translucent. This is known as 'man nourishing jade, and jade nourishing man.' However, 'playing' here does not mean vigorously rubbing it with your hands, but rather normal wearing and touching. If not worn for a long time, jadeite may appear dry and lose its luster. Therefore, I suggest that you wear your beloved jadeite more often.
* Joy of Moisture: Jadeite prefers a humid environment. If not worn for a long time, it can be stored in a relatively humid environment, for example, by placing a small cup of water in the jewelry box (be careful not to let it directly contact the jadeite), or by regularly taking it out, rinsing it with water, and drying it. This helps maintain the internal moisture of the jadeite and slows down its 'dehydration' phenomenon.

Real Cases and Precautions:

I have a client who collected a superb old pit glass-type Guanyin pendant. He usually cherished it greatly, but once, he left the Guanyin pendant in his car, exposed to direct sunlight for a long time. When he remembered it, the surface of the Guanyin pendant had developed some tiny 'dry lines,' and its luster was noticeably inferior to before. This is the direct damage caused by high temperatures to jadeite. Therefore, even for brief placements, pay attention to avoiding high-temperature environments.

Furthermore, there's a widespread saying about 'oiling' jadeite. My advice is that unless it's professionally treated jadeite (like B-grade, C-grade, which are not recommended for collection anyway), natural jadeite does not require additional oil. The oils secreted by the human body are sufficient. Too much oil might even clog the jadeite's pores, preventing it from 'breathing,' and even attracting more dust.

Experience Summary:

Jadeite maintenance lies in consistent, meticulous care. It's not a cold object, but something with life and spirituality. If you treat it well, it will naturally reward you with a gentle luster and the patina of time. Remember the 'three fears and three joys' principle, integrate it into your daily wearing and collecting habits, and your jadeite will surely remain new and radiant over time. Collecting jadeite is not just about owning; it's a kind of inheritance, a dialogue with the essence of heaven and earth. I hope my experiences can help everyone better care for their treasures.
