New Find: Blue “Cloud Agates” from Weierbach near Idar-Oberstein, Rhineland-Palatinate

, Lapis, , No. 6, 2012,

The agate deposits that formed the basis of the lapidary and cutting industry at Idar-Oberstein until the 19th century are mostly depleted. What reaches the market today is the result of rockhound activities. This article reports on a remarkable find from 2012 along a road construction site at Weierbach, near Idar-Oberstein. Found in a small outcrop of volcanic rocks, the nodules showed diameters of 2–12 cm (0.8–4.8 in.). While agates from Idar-Oberstein generally have a fine banding and pastel tones, most of these agates were not banded but showed cloud-like structures and striking sky blue and red colors. The article contains numerous images of the splendid agates and the deposit.
