The variegated shape of this succulent presents the typical yellow zones, or in even rarer cases pink, in the exact points where the chlorophyll is absent; such zones will never be identical from one plant to another, thus making each exemplar absolutely unique and, for this reason, very sought after by collectors. The name of this "living stone" comes from the brackish habitat where it was found for the first time. It has a grey-bluish body, with the upper part of the fleshy leaves of a darker grey, covered by pleasant pale maculatures. It consists of only two fleshy leaves separated by a fissure, from which comes the large and elegant pure white flower. It is very prone to rottenness due to excess water and moisture, so it requires the maximum of care in cultivation.
