Jade can be washed directly with water, but be careful not to wash it with liquid containing acidic components, so that jade will be corroded, and strong alkali will also corrode if it cannot be used. After washing with mineral water, dry it with a soft cloth. Don't blow dry it. Water stains will remain on jade, which will affect the appearance. It is best to use liquor lotion, but don't use alcohol. Jade is an article made of natural jade. China had jade articles as early as 8,000 years ago, and they have continued to this day. The appearance of jade is the continuation and innovation of ancient stone tools.

The difference between jade and stone tools lies in the difference in texture and processing methods. Raw natural jade is jade material. Shuo Wen Jie Zi says: "The beauty of stone is jade", and all beautiful stone products are within the scope of jade. The jades in Shi Mei are mostly interwoven with tremolite and actinolite, which is different from the stones that can be hammered into shape.

Therefore, the appearance of ancient jade lies in the fact that the ancients in China in the late Neolithic period created a method of grinding jade with jade-solving sand. Ancient jade is a unique artifact of Chinese civilization in ancient human civilization.

Because the ancient grinding method has been lost, the jades made by grinding method are all ancient jade, and the jades processed by modern techniques such as electric diamond tools are called new jade. Jade articles in China have been of the highest specification since prehistoric times, and are mainly used as ritual vessels and ornaments.

There are many varieties and styles of modern jade ornaments, including: jade beads, jade bracelets, jade pins, jade pendants, inlaid ornaments, jade rings, gold inlaid jade products, jade belts and so on. In addition to jade, agate, secret jade and other jade materials, jade, green gold, chicken liver stone, malachite, Dongling stone, coral, crystal and so on are also used.

Specifications and styles are constantly being renovated, and single bead strings include flat strings, pagoda strings, colorful strings, shaped strings, conformal strings and so on. These jewels and jade ornaments, through careful wearing, will give people a perfect combination of life and clothing.

In China, jade is synonymous with beautiful stones. The ancients regarded jade as a treasure, and today people call precious jade Baoyu. China is a country of jade, but in the jewelry, archaeology and geology of China, the definitions of jade, jade and precious stones are different.

Internationally, jade refers to nephrite and jadeite (jadeite), and other jade carving stones are collectively referred to as jade. Gem is a collection of one or more minerals with special optical effects, and most of them are single crystals of certain minerals, such as diamond, ruby, sapphire, emerald, opal, tourmaline, purple tooth black and so on.
