Most mineral specimens are prepared by trimming and cleaning which may be done by hand with water and detergent, with ultrasonic devices, physical abrasive cleaning devices and/or a wide range of chemical cleaning products ranging from organic acids such as acetic acid through to hydrofluoric acid.

Broken specimens are sometimes repaired (where a simple clean break is repaired) or, in certain cases, restored (where missing material on the specimen is replaced with similar natural and/or resin to repair more significant damage.) All such repairs should be disclosed.

Some specimens are treated with heat and/or irradiated to change either the color or the intensity of the color to increase marketability. This, again, should be disclosed but rarely is.
