Snowflake Obsidian is said to purify and ground body, soul and aura. It centers and focuses attention, which can be really useful in chaotic or stressful environments. The black of the obsidian and the white of the snowflakes represent the balancing of dark and light, and this stone is known to be a bringer of balance between two opposing sides.
There are many dualities that the stone symbolises. It helps you see the bright side and reminds you that even though you will encounter tough times, there will always be light inside yourself.
In meditation, it facilitates looking inward and finding the inner strength to overcome whatever obstacle is in your path. It is protective of both your space and your aura, so it is useful for keeping your space calm and balanced, and also for shielding you from the negative energy of a toxic coworker or family member that you are unable to avoid.
