For example, the aforementioned emerans larger than 3 carats, Shafflei, which is larger than 5 carats. These goods are rare in the market and the price is naturally high. Generally speaking, the larger the gem particles, the more rare and precious, the higher the price. However, the rareness of different gems is different.

When the sea blue gem and Opal are larger than 30 carats, the weight unit price does not rise and fall! Because the color is light in color, when the gem particle is large, it is easy to gather color. When people's view is the same, it means that the real color of the large particles is smaller. The increase in the granules of the sea blue gem can deepen its color, but the color will be gray and blue, not smart enough, and the large particles are not suitable for jewelry. Opal is a block -shaped collection. Large raw materials are common. When it is larger than 30 carats, it is necessary to cut it to be suitable for processing into jewelry. Therefore, when Opal is more than 30 carats, the unit price will not rise and fall. Hetian Yuzi material is an obvious example. The unit price of the kid is higher than the unit price of the large piece of material (see "Old Hou Say Yu -the Appreciation and Valuation of Hetian Yu").
