The materials and colors are all natural. Although the color of your amethyst photo is a little evil, the color of this amethyst is slightly different from the background color of your photo-there is no problem with the color!

At present, the glue injection in the market is mostly used for tourmaline and jadeite. Some high-value titanium crystals and hair crystals will be soaked in oil and can be seen at the ice crack position of the crystals with an ordinary magnifying glass. You have no problem!
