The common red color is due to iron(III) inclusions. The mineral aggregate breaks with a smooth surface and is used for ornamentation or as a gemstone.

Heliotrope (building) a garden terrace. The solar panels can be used for sun or rain protection while on the roof terrace. All floors are accessible from the spiral staircase reducing surface loss through hallways and corridors. Further potential for this building design includes plans that were drawn up for a possible Heliotrope Hotel. This project currently has no customers but was designed to show that the revolving design can easily be scaled up. The plans for a rotating hotel have surfaced on several occasions although the financing has not yet been available for its actualization. Heliotrope (building) The Heliotrope is an environmentally
