Generally, good goods are not made into beads for sale. Generally, the materials used for beading are scraps left after cutting and polishing, or because the interior is impure/incomplete or cracked, it can't be cut and polished into inlaid gems, so it is made into beading. The price is naturally very cheap, and loose beads are sold by kilograms from gem processing plants or mine owners. Therefore, according to different purchase channels and different purchase costs, it is possible to earn ten times. In short, more than 400 is expensive. If you buy it online, because there is no store cost, the price of 100-200 is more reasonable according to the different wholesale channels of shopkeepers.

PS: The price of the best powder crystal on the market is not low either. Pricing by carat, ranging from 10-30 yuan/carat, depending on color and cleanliness. If calculated at this price, the authenticity of this string of things is questionable. Those who like powder crystals can go to Taobao's "Rongji Jewelry" to have a look. There are bare stones to inlay.
