Some are obvious, others are not. If you have agates that are in blues, teals, green, pink, purple, they are obviously dyed.
Howlite is often dyed too, yellow, pink, blue, green etc. and is often passed as turquoise.
Crackled quartz is also dyed.
Others are done so subtly that you need high magnification, intimate knowledge, or special testing to tell.
Of course then there is heat treating, chemical bonding, and lab grown crystals to consider too.
If you have clear pictures we could help you identify them.

It is true that agates in blues, teals, green, pink, purple are mostly dyed. But they do exist naturally also. For more info, please visit: http://www.gem.org.au/galleryf.htm

I love to make jewelry using the healing power of various semi-precious stones. Some poor grade stones are dyed the color they should be...like citrine can be clear with very light yellow spots in it, or it will not have consistent color through the bead so they will dye it yellow so it looks good.
