Crystal grids are a great way to amplify energy around a special intention or focus. These mini's are meant to be transportable and easy to use whether at home, office, or traveling! This set contains a rainbow flourite center stone for clarity with four quartz points to act as amplifiers. The set comes in a protective tin for easy transport and nestled in sea salt which clears old energy and restores the crystals to their natural energetic state in between use. There is also an affirmation card and instructions. Please remember that every crystal is unique, so your crystals may vary in look, shape, and size. Some center stones are tumbled, some are raw. I hand select each set. Please know that the set you receive is exactly the set meant for you. Crystals are approximately between 1/2" to 1 1/4" in size, grid when set up will be about 3 or 4" square. Oh yes - and the affirmation card is made from 100% recycled t-shirts - no trees!!
