These stones — which belong to the zeolite group — are popular with collectors due to their rarity and unique, needle-like crystals. Described as a "high-vibration crystal," natrolites are believed to be one of the strongest varieties of zeolite stones and are thought to shield your energy from negativity around you, whether that's a mean coworker, your own negative thoughts, or even toxic products or smells (there are several bath soaks availability containing zeolites that promise to detox, although, it's important to note that there's no concrete studies or science behind any of these products at this time).
If you're about to enter a phase in your life with lots of change, perhaps a new job or moving — natrolite can be used to make yourself feel empowered so that you're always confident in whatever you do, helping you to achieve tasks that would've otherwise given you a lot of difficulty.
