a mineral of the nesosilicate class, with the composition 2Mg2[SiO4]Mg(F, OH)2. Chondrodite contains admixtures of Fe2+ and Mn. It crystallizes in the monoclinic system, but well-formed crystals are rare. It is found in the form of grains embedded in rocks and in the form of granular aggregates. The color is orange, honey, yellow, or red-brown. The hardness on Mohs’ scale is 6.5, and the density is 3,250–3,300 kg/m3. Chondrodite is a typical mineral of contact metasomatic formations. It is widespread in magnesian skarns in association with olivine, diopside, magnetite, and other minerals. It has also been found in calciphyres and carbonatites.

However, by 1993, when most of the Kiss collection had been acquired, more specimens of similar appearance and association were found, this time labeled "humite or chondrodite (?)." Qualitative testing indicated that the yellow mineral is not a humite-group mineral, because it possesses a high specific gravity, is insoluble in 1:1 HCl, and shows at least one good cleavage.
