Name(s) in local language(s): Safírový potok a řeka Jizerka, Osada Jizerka, Liberecký Kraj, Česká Republika
 
Small placer deposit known at least since the 16th century. Heavy minerals come from Quaternary gravel terraces (0.5 to 2 m thick), mostly covered by 0.2 to 3 m of peat.

Mineral association: zircon (up to 30 %, max. 9 g), ilmenite (up to 25 %) and titanite (up to 20 %). Ferromagnetic Mg-Fe3+ variety of ilmenite is called iserine - mostly 2 to 20 mm black pebbles. Largest known sapphire 12 mm. Part of minerals came from surrounding granites, gneiss, and their accompanying vein rocks, including from quartz veins.

Some minerals photographed by Lukáš Jankaj may not be from this locality: e.g. alexandrite, aquamarine, beryl, gold, emerald, topaz. (comment by P. Škácha)
