Dimensions: The size of the crystal chips is fairly consistent and most of the small crystals have at least one side 5mm long.
Crystal chip bracelets are small tumbled pieces of crystal strung together on an elastic thread. The difference between these bracelets and power bracelets is that power bracelets are specifically carved into spheres and these are left a more natural shape. They are smooth crystals so will not 'dig in' to your skin. They will carry the same properties as an equivalent power bracelet. The decision is purely which you would prefer to wear.
Crystal chip bracelets are cheaper than power bracelets because there is not so much production involved in making the crystal stones the right shape for use. Also the crystals themselves are marginally smaller.
More About Mother of Pearl Strictly speaking, mother of pearl isn't actually a crystal - it's a form of shell that comes from the internal lining of the abalone or pearl oyster shell. The energy of mother of pearl reflects its delicate nature, by giving off an air of sensitivity, relaxation and love. It can soothe the senses, ease stress and worry, and remind us of the importance of expressing our true feelings, rather than keeping them bottled up.
