Smokey Quartz (Malawi) #4 measures approximately 1 1/4" x 3/4" x 5/8" (31mm x 23mm x 18mm) and weighs approximately .4 ounces (11.1 grams). The off-white crystal is likely some sort of Feldspar. These were in the flat with the Smokey Quartz with Aegirine Inclusions, but they have no visible Aegirine. I believe they carry the energy of the Aegirine, too.

Smokey Quartz is most effective on the Solar Plexus Chakra as well as the Minor Chakras of the Hands and Feet. (Every healer knows the Chakras of the Hand and Feet are not Minor Chakras!) It dispels negative emotions (anger, resentment, and negative thought patterns), emotional blockages, and negative energy. This crystal also provides excellent protection and grounding. It's a very good crystal to use for meditation. This crystal's energy is gentle, and it takes time to do its work.
