Yes quartz crystals are readily programmable and imprint with your intention quite easily!

The optimum imprint programming and clearing protocol I have found most effective and universal:

Programming a crystal

1. Place one or two fingers or a thumb on a specific crystal face.  If the crystal is not faceted, such as a sphere, then hold the crystal.
2. Visualize what you want it to imprint
   • a scene that expresses a feeling, or
   • a thought or verbal affirmation (which need to be started with ‘Why’ e.g. “Why is my problem with____ completely resolved?” which better activates subconscious power), or
   • a future scene that symbolizes an accomplishment, etc.
3. While visualizing, also amp up the associated emotional/energetic component, the more love the better, but even simple directed will (intention) works, but feeling added supercharges it
4. As you visualize that image and feeling flowing into the crystal – preferably with eyes closed or eyes cast into the crystal face (both work) – also squeeze or press your finger(s) onto the crystal face in sync with that visualization.
5. If complex and not simple, do it three times.  Each time with gusto, and a short rest thinking about something else in between.
6. If major and far reaching change wise, here is a special turbo-manifestation technique: visualize, feel and press onto the crystal facet for exactly 33 seconds, no more, no less using a 33 countdown timer with a beep to stop (if eyes are closed while doing this).  With gusto, but drop the visualization and emoting like a rock at 33 seconds.  For some reason this seems to sync up getting help from higher dimensional factors.  (Don’t worry, it’s cool, there is nothing strange or demonic here, it simply gets you the right dial tone to your own higher forces of manifesting your desire.  If you desire something negative or harmful to anyone or to a crystal, be careful, you can get karmic blowback real fast.)

Clearing a crystal

1. This often needs to be done before doing #1 above, don’t want conflicting programming in play.  And crystals like to be free of programming as much as they like to be agents of reality programming.
2. Crystal cleaning, rest in a solution of salt water (from sea or sea salt, about a teaspoon or more per 2 cups of water, for 30 minutes will do it.
3. Crystal clearing, press thing or fingers, right hand only, onto each of the crystal facets or faces, and visualize a blast of white light coming out off your hand from your heart into the crystal while pressing the face in sync with that, and while sharply exhaling breath in sync with that.
4. If the crystal has only one face (tabular flat) or one surface (rounded cabochon) just only need to press that with thumb and hand underneath.
