It forms beautiful, regular octahedral crystals such as the one shown here. Normally alum crystals are colourless, but if the 'normal' alum (KAl(SO4).12H2O) is mixed with 'chrome alum' (KCr(SO4).12H2O) then the crystals will have a purple colour. The samples you will be sent if you pay for it. We will allow you to grow these purple crystals.
