Description
bismuth (lab grown) crystal rarely occurs in nature... the colors come from oxidation of the surfaceused in cosmetics and medical field as well as other applications (especially replacing lead which is much more toxic)

Dude the cubeish shape is phenomenal can you tell me how that happens

simple explanation is crystals grow depending on how the molecules fit together- other influences like temperature differences or impurities determine the ultimate shape. check out en.wikipedia.org/wiki/Crystall⦠for more detailed explanation.

sa fait 18 ans que j'en ait et je vien d'apprendre que c'est radioactif ^-^
its fact 18 years that I have some and I has just learned that it is radioactive ^-^

Recently it has been found to be very slightly radioactive: its only naturally occurring isotope bismuth-209 decays via alpha decay into thallium-205 with a half-life of more than a billion times the estimated age of the universe.[2]

i wonder why it grows that way? it seems so precise and organized.

One of my char's last name is Bismuth, was inspired by a pic of it like this one. This is such a beautiful picture, I wish I owned some.

thanks! check at a rock and mineral show in your area... usually some is for sale and it goes pretty cheap- like $10

I have a bismuth crystal. They break so easily. :[ Mine broke in half.
Also my mom had an older crystal I had when I was kid and put it in her pocketbook then put the pocketbook in a hot car. it..melted. It actually melted. Amazing. LOEV BISMUTH

You own a piece? I've heard it's somewhat toxic. How true is that?

Bismuth compounds are used in cosmetics, medicines, and in medical procedures. As the toxicity of lead has become more apparent in recent years, alloy uses for bismuth metal as a replacement for lead have become an increasing part of bismuth's commercial importance. - wikipedia
thanks for the fav!

Is that what that's called? I have a pendant of that, & new it was geological or mineral, but no idea what. I got it at the Discovery Museum in Galveston, Tx.

I would LOVE to have one of these. Are they costly?

relatively cheap- this particular one ( aprox. 1" x 1" )cost $10 a few years ago- if you have a rock and mineral show or shop near by, check it out!

The colours really are beautiful. I love this specimen the shape is fantastic.

thanks!, bismuth has always been fascinating to me

I love the way this stuff looks. I got a piece of it somewhere when I was a kid and always wondered where such a cool rock came from. I later found out that my piece was created in a lab. I still love it

yeah- it's not only the colors but the layers and geometry of the crystal that makes it so cool
