What is the material of imitating dzi beads and how is it imitated?

Imitation dzi beads refer to dzi beads made of agate or chalcedony. Such as resin, ceramics, serpentine, glass and antique beads made of marble-like materials. Leather weathering patterns are about 80% similar.

Simple hardness comparison method: As long as the beads are forcibly drawn down to the glass table top, a line can be deeply carved on the glass table top. According to the materials used in the new Tianzhu beads, it is possible that the agate texture (agate hardness: 6.5~7) will not damage the beads.

If the beads are damaged and the glass is not damaged, it is softer than the glass; If both beads and glass are damaged, they are as hard as glass, and none of them will be agate or chalcedony. The following data is for your reference.

1, resin: organic matter has extremely low hardness and can be scratched with a knife.

2. Ceramics: Hardness is less than that of glass.

3. serpentine: the English name of Serpentine jade is Serpentine Jade, and the craft name is Xiuyu. White stripes, waxy luster, translucent, slightly transparent to opaque, Mohs hardness 4.9-5.5.

4. Glass: In order to distinguish between glass and agate, there is actually a very simple method besides observing whether there are bubbles with a magnifying glass, that is, hardness comparison method. The Mohs hardness of glass is 6. When comparing the hardness of substances, you can also use other things instead, such as a knife with a hardness of about 5.5; Copper coins are about 3.5 to 4; There are about 2 to 3 nails; The hardness of glass is 6.

It is generally recommended to use glass for comparison. Glass is more common and easy to obtain.

Extended information about the legend of dzi Zhu;

The dzi bead, also known as the "Eye of the Sky", is a rare gem, which is mainly produced in the Himalayas such as Tibet, eastern Tibet, Bhutan, Sikkim and Ladakh. Tianzhu is a nine-eyed shale, which contains jade and agate. It is one of the seven treasures, and it is recorded as "Nine Eyes Stone Tianzhu" in the history books. Tibetans still believe that dzi beads are celestial stones.

The Tibetan pronunciation of dzi Zhu is "Sisi Lee", which means beauty, weeds and wealth, while the Sanskrit is "Ignorant Tibetan ancestors thought that dzi Zhu was a supernatural thing created by God, naturally generated or descended from the sky. Anyone who says handicrafts is strongly opposed.

Ask many Tibetans where the dzi beads came from, and they all tell the same old myth: in ancient times, dzi beads were ornaments worn by immortals. Whenever the beads are damaged or slightly damaged, the immortals throw them along with the biological fossils, which is the same era as Nautilus and trilobites. Some people have presented evidence that the fossil of dzi beads has been seen in the Dingri area of the Himalayas and the fossil mountain in the no-man's land of northern Tibet.

The story of the common people goes like this: once a man saw such a bug on the top of the mountain, he threw his hat at it and covered it. When he took off his hat, the bug had petrified and turned into a dzi bead. In the article "Prehistoric Beads in Tibet", Dr. R. Nebesky-Wokowitz tells a legend in Ali area in western Tibet.

People think that dzi beads originated from a mountain near Ruddock, and they go down the slope like a stream when it rains heavily. However, one day, a witch stared at the mountain with "evil eyes", so the dzi beads stopped flowing at once. Until today, you can still see the distinctive dzi beads with black and white stripes in the place where dzi beads keep flowing out.
