As stated above most gemstones emit an energy of their own and so I don't believe that any act to disrupt magical in general although there are many that can be used as protection against unwanted magical energies (quartz for example), to absorb negative energy (jet) or to help convert it into positive (black tourmaline).
All such stones act as protection against unwanted energies, they won't disrupt spell casting but they help in shielding you from others.
