Although not suitable for jewelry, apophyllite is a popular collector’s piece. Perhaps the whitest of all gems, some cut specimens are so devoid of color they can appear almost silvery. This stone is not rare, but facetable material is quite scarce.

Apophyllite also has great heat sensitivity. The heat from a jeweler's torch may cause these gems to exfoliate. In other words, true to its etymology, apophyllite may lose flakes or "leaves" of material if heated. Setting a faceted stone would be difficult. With a hardness of just 4.5 to 5, any apophyllite jewelry stones would need protective settings. Reserve these gems for occasional wear.
