This pendant was made bij cooling liquid bismuth, during the cooling process crystals are formed on the surface. You will recieve the exact bismuth crystal from the picture, The dimensions are 3.1 x 2.8 x 1.4 CM Let your own heart decide what this bismuth crystal can give you, or even better what you can bring each other. For it is an exchange. Just open you heart and imagine how it will be. Bismuth is a crystalline, brittle metal that is silvery-white with an iridescent hue. As an elemental metal, its number is 83 on the Periodic Table. Bismuth is a heavy, brittle silver-white crystalline that transforms with tinges of pink to red. It naturally occurs with an iridescent oxide tarnish that reflects a full spectrum of colors including blue, yellow and green, as well. Bismuth crystals are typically laboratory grown where Bismuth is melted and a rod is placed in the molten metal and pulled up slowly, which allows crystals to form as it cools.
