A few other minerals are associated with blue lace agate. Dogtooth and other forms of calcite crystals, clear quartz, gypsum, dolomite, ankerite and small, golden blocks of siderite have been noted. Here is a selection:
Calcite and siderite – view 3 cm
Calcite – view 2 cm
Dog tooth calcite and siderite
