Two French Sandstone Concretions--'Gogottes'
Oligocene
30 million years old
Fontainebleau, France
A gogotte is a millions-of-years old naturally shaped mineral rarity consisting of tiny quartz fragments held together by calcium carbonate. A mineralogical work of art, each gogotte has a unique and otherworldly shape, which opens the imagination to infinite interpretations. Fontainebleau's sand is famous for its flawlessness and delicacy since the 17th century, and gives the gogotte its porcelain appearance. The two Gogottes are of medium-size, beautifully presented. 23 x 15 x 13 cm ; 16 x 16 x 12 cm (without stands). Measuring 40 x 12 x 12 cm and 32 x 13 x 10 cm, inclusive of stand (2)
