Abstract

A heat-resistant synthetic jewelry material having a transparent, semitransparent or nontransparent composite nanocrystalline material on the basis of nanosized oxide and silicate crystalline phases. The material includes at least one of the following crystalline phases: spinel, quartz-like phases, sapphirine, enstatite, petalite-like phase, cordierite, willemite, zirconium, rutile, zirconium titanate, zirconium dioxide with a content of ions of transition elements, rare-earth elements and precious metals of from 0.001 to 4 mol %. One of the crystalline phases is additionally quartz-like solid solutions of lithium magnesium zinc aluminosilicates with a virgilite or keatite structure. The composition is selected from the following components,s SiO₂, Al₂O₃, MgO, ZnO, Li₂O, PbO, ZrO₂, TiO₂, NiO, CoO, CuO, Cr₂O₃, Bi₂O₃, Fe₂O₃, MnO₂, CeO₂, Nd₂O₃, Er₂O₃, Pr₂O₃ and Au.
