Ruby:
For officials from the first rank to the viscount level, the top beads on the top hats are all red gemstones. There are too many titles for rubies, what is the king of colored gemstones, the stone of love, one of the five high-grade gemstones, very rare, so it is very precious. However, most red gemstones are classified as spinel, not rubies, because rubies and red spinels are symbiotic minerals, and there is no identification technology in ancient times, so they cannot be distinguished. In addition, red has been an auspicious color since ancient times. Therefore, the ruby is also a symbol of good luck.
Coral:
The Chinese have a deep love for red, and when the ceremony is held, the emperor wears red coral pearls. The top of the hat of the second-grade official is coral, and the color is mostly red, and the bright red is the most precious. The quality of the red coral top beads of the second-grade officials is not the same, and the color is not the same, and some officials use the most precious ox blood red coral, which is second only to rubies in value.
Sapphire:
Lapis lazuli is only the imperial stone of our country, and sapphire is recognized as the imperial stone all over the world, so it should be assigned to higher-ranking officials. Compared with the rubies of the first official, the production and variety of sapphires are a little more. It is a high-grade gemstone, one of the five major gemstones, after diamonds and rubies.
Lapis lazuli: Lapis lazuli was known as the "Emperor's Stone" in ancient China, also known as "Xuanlin", "Jinjing", "Jinyu", "Qingdai" and so on. Only such a domineering gem can reflect the identity of the four-grade official.
Crystal:
The top beads of the five-grade officials are crystals. Crystal is transparent and a precious mineral, although in modern times, the status of crystal has declined. However, in ancient times, this kind of transparent, colorful, and hard gemstone was very popular, and it was affectionately called "water jade", "water spirit" and so on
Su Jin:
The seven-grade officials also use the golden top. The difference is that the top beads of the seven pins are plain gold. Plain gold means gold that is not set with any precious stones, but it is also not openworked. It is definitely worth more than eight or nine grades.
砗磲:
From the sixth pin, the hat is inlaid with gemstones. Liupin top bead is one of the "Seven Treasures of Buddhism" of the Tridacn, the texture of the Tridacnus is hard, white as jade, since ancient times is a symbol of auspiciousness, wealth, so it has become the standard dress of Qing Dynasty officials, it is not surprising at all.
镂金:
Qing Dynasty eight-grade and nine-grade officials all used openwork gold tops. The difference is that the eighth grade is made of Yin Wen carved gold, while the ninth grade is Yang Wen carved gold.
