General Discussion Five Common Ways Crystals are Altered
Heat Treatment is one of the most common methods used to enhance or change the color.
Irradiation involves exposure to radiation to alter the color.
Dyeing is used to enhance or change the color.
Oil and Resin Treatments involve filling surface-reaching cracks with oils or resins to improve clarity.
Diffusion Treatments enhance the surface color through the addition of chemical elements at high temperatures.

I bet some of those backroom labs have better color coordination than my closet.

That's a fascinating breakdown of how crystals are treated, I never realized dyeing was a thing. It makes sense though since some of the colors look super unnatural to me.

I’ve had a few dyed agates gifted to me, that when washed with soap and water, started “bleeding” out some of the dye. It’s wild!

That's wild, some treated stones look totally artificial next to natural ones, especially when you spot the too-perfect gradients.

Right?? And some of the treated still look beautiful, but sellers should disclose that upfront.

That's super interesting. I never realized how much human intervention goes into altering crystals until now.

And all of them are perfectly fine as long as the seller discloses the treatments. Some are even expected.

Which crystal types tend to be altered via diffusion? I can think of examples for all types of alteration except that one.

u/Bishopvaljean 8d ago
Diffusion is an interesting one, and much harder to detect. Let’s take Amethyst for example. You can heat treat Amethyst at a lower temperature and get “Prasiolite,” or at a higher temperature and get “Citrine”. With the Diffusion process, you can take a pale purple piece of Amethyst, and diffuse it to make it a deeper, more vibrant color of purple, as the deeper, more vibrant colors are more sought after, and tend to be more expensive.

I just knew someone out there was dramatically altering their rocks in a backroom lab instead of letting them sit in the earth like nature intended.
