27 x 20.8 x 5 mm.
4.03 grams - 20 carats.
Manganese dendrites and iron oxides in a clear and translucent girasol quartz.
Several beautiful dendritic trees on a yellow ochre background for a beautiful cabochon in the shape of a boat sail.
In anticipation of a crimping I made a slight bias on the blank, the back is polished with a small chamfer on the edge.
A little bit of geology:
A few hundred million years ago, when quartz formed in the depths of the earth under the effect of circulation of hydrothermal fluids, tiny cracks formed in the rock in a fairly horizontal plane. Then, the mineralization of the fluids having changed, they were loaded with manganese and hematite, penetrated into the cracks and then crystallized on the walls of the quartz giving these magnificent biomorphic figures of plants, lichens, corals, trees ... We can observe this kind of pattern when in winter the water crystallizes by the frost on a window.
The word dendrite comes from the Greek -dendron-, tree.
Like all the other articles published buying on my shop this stone was sawn, cut and polished in my workshop located in the north of Burgundy.
