Ask the crystal, platinum, diamonds, emeralds, platinum, jade, agate, gold, yin, copper per gram?

First of all, there are many types of crystal, the specific price is different, and some are calculated according to the number of grams. Kak, calculate the price according to the finished product. For example, agate is a type of crystal. The price is relatively low. Generally, a string of a little agate bracelet is a maximum of thousands of yuan. Of course, this is not absolute, but it also depends on the comprehensive setting of color. I don't know what you want to ask if you want to ask, whether or the decoration or the rough of the crystal.
2, jade is divided into two categories: liffing, that is, we usually say emerald, jadeite uses glass species as the top product. For example, the emerald bracelet is available from more than ten yuan to 100,000 yuan or even millions of dollars (the same is true for jade pendants). The emerald rough is generally sold in kilograms, which is sold, and of course it depends on it. It is commonly known as the color. "Gambling stones", I do n’t know how to tell you, what you ask is too unclear; the second category is nephrite, Hetian jade, Saitama, Lantian jade, and Nanyang's Dushan jade belong to the nephrite, of which Rate jade is used as the top product, the price is relatively high. The best of Hetian Jade is sheep fat jade. Hundreds of dollars, high tens of millions of yuan.
3, platinum is not calculated at a gram of grams, priced at the finished product, and there are several types of 24K, 18K, 14K, etc. The price is lower.
4, the gold price of gold will float every day. The current price of gold shops is 99.99%of the price of about 240 yuan/gram, 99%of the gold, 18K gold, and 14K gold. Golden shop to ask.
The silver price is about 5 yuan/gram
The copper price is not known, you can ask for waste.
5, diamonds are based on carats, depending on the specific situation.
In the last thing you suggest that you must be a little clearer when asking questions in the future. I do n’t know what you want to know and hope to help you. Haha, I remember that there is a reward for reward next time, don't be too stingy.

And dear, the emerald agate jade is generally not sold. Diamonds have a good carat, and there is 5 carats if you grams. Then, you are really stingy.
