We bought these mosaics as trivets for the dining room table because the octagon symbolizes the flow of love and these octagons look very pretty. The colored stones have the colors of the body chakras and also the children like to play with this. Every week we have another mosaic pattern on the table. The colors of the rocks are stronger than on this product picture. The Bovis units of food to rise in this product of 8000 measured eg drinking water to over 30,000 units within a few minutes, if you plan sets in.
