I'm really unsure as to what this specimen is. It was reported to have been smelted and given to a friend who provided roadside assistance to the gifter. It was reportely poured in a heart shape and apparently has been sliced in half to expose a myriad of crystall inside. It is spectacularly colorful in direct sunlight and when moved relative to a light source. My read is that berylium is toxic to handle and breath and thus I'm unsure why anyone would make a decorative piece of it. It is dense, primarily gold in color similar to pyrite, and going to remain wrapped in plastic until I find out more about it.  20240327_100904 by Thomas Fritts, on Flickr |

Bismuth crystal. Has a very low melting point, and so these crystals can be made using your stove top.

Yes, bismuth is a low melting point metal. The giveaway that this is bismuth are the squarish crystal shapes. Oxidation of the surface will form various bright colors.
You can make these crystals from Pepto Bismol, which is a bismuth aspirin compound, but it is much easier to just buy the metal and melt it in an old pan.

That is definitely Bismuth.

It is bismuth.

Bismuth, if it was beryllium there would be an armed guard with it.
