RE:

Are colored geodes synthetically made?

I love collecting and finding rocks, and from the time when I was a small child geodes were some of my favorites. However, I can't help but wonder if all the brightly colored geodes are made in nature. Are they found and then dyed in a laboratory or made from scratch in a lab? I was just...

Answer 3

When you see the vibrant pink, purple, red, and blue, then the answer is yes. They are either dyed or heated. The natural geode quartz can be turned those colors with enough heat. The ones turned into bookends are often dyed during the polishing process.

Answer 4

Your rock is probably natural. Your rocks are most likely dyed agate. It's common to see dyed agate. Agate can be dyed because it is able to absorb amounts of dye and water. It is usually a translucent rock that has layers of crystals. Agate is naturally brown, gray, white, translucent, or green. If it's an outrageous color, it's most likely dyed. It contains silica, which is glass. Most rocks containing this chemical can be dyed. Some other examples are quartz. There are many different types of quartz like rose quartz (light pink), amethyst (light to deep purple). These are found in nature and their colors are natural.



Other examples of rocks that are able to be dyed: Jade, Howlite

Answer 5

There are many colors of geodes, but some are dyed. The amethyst (purple quartz) are the most common natural geodes, they actually are that color. Ruby and emerald geodes are also natural but are more rare. All those pretty ones you see on store shelves that are smooth with pretty colors like dark blue are not natural. They are still natural geodes, but somebody has dyed the agate to make it more desirable.



This is a natural geode with no added dyes or colors. http://www.mountainmystic.com/images/old_site/amethyst_geode.jpg



These are still natural geodes but somebody has dyed the minerals to make them prettier.

I have collected rocks since I was little as well, and have about 108 geodes that I dug up myself in california. I am currently studying geological science so I know a lot about them =). Hope I answered your question =)
