12 grams of bottle 10-15 grams of minerals It is fragile, please be careful to store it,thanks! Crystalline bismuth is made from the melting of high purity bismuth metal when slow cooling crystallization,the density is about 9.8 g / cubic centimeter, with a complex and rules shape. Crystal bismuth will be oxidized during the production process, resulting in a variety color of the oxide film, it is very bright!!! Due to the shape and color of each one are formed naturely during cooling , so there is not same one as the photos, each one is unique shape and color , we only can make sure the weight is matched . There are different colors, we will send it to you random!!!! We still have a lot of metals and elements not listed, if you are looking for them, please contact us!
