Rose Quartz is very brittle so when working with it you must keep this in mind. Some times quartz will have inclusions (minerals that are not part of the main stone) that often will make the specimen perfect for a one-of-a-kind piece of jewelry.
Rose Quartz is also used for spiritual purposes; the stone is said to bring positive energy and to help heal the body and mind. When purchasing Rose Quartz as a spiritual tool you should "cleanse" the stone first prior to using. To cleanse the stone you use one of the four elements - fire, water, earth, or wind. The easiest method that I find is to use sea salt in a deep container and I place the rocks into the salt and seal it for at least 24 hours. You can also use dirt (messier), water (may damage some stones but not the quartz) or pass it through the smoke from a lit candle. There are many sites that will provide significant more detailed information on how to cleanse your stone this is just a snippet.
You also need to "charge" your stone, which can be as simple as leaving it on the window sill in the sunlight for at least 24 hours. Again googling this will provide much more detailed information that this. But you also will have to cleanse and recharge your stones often for them to be affective. I even do this with my jewelry that is made out of real stone. Especially after I first purchase it, who would want another person's energy or Karma? My methods are just suggestions there are many other ways to cleanse and charge your crystals. This site will get you a great start if you are interested in the energy from crystals: http://www.millenniumminerals.com/resources/clean.html.
