Mosaic is a semi-precious stone. The stone thanks its name to the green inclusions (drawings) that resemble moss. Mosaic is a variety of agate. The white background of the mosquito consists of quartz. The dendritic inclusions are chlorite or iron and manganese minerals which are very similar to moss. Depending on the valence of the metal, the inclusions display different colors. Mosagat therefore contains no organic material despite its name. The stone is formed of weathered volcanic rock. The chemical structure of mosquito is identical to that of jasper, flint and hornet, all of which are also quartz variants. The green / blue / red / yellow and brown stones are polished / sharpened for jewelry or as talisman. The main locations of mosquito are India, China, USA and occasionally in South Africa and Brazil. Mosaic is found in the United States, among other things, in the deposits of the Yellowstone River and its tributaries, between Sidney (Montana) and Billings (Montana). In this variant, Montana called mosquito, the red color is caused by iron (III) oxide (rust) and the black by manganese (IV) oxide.

Heliotrope is a mineral and a variety of quartz, more specifically a variant of chalcedone. Heliotrope is a two-tone nesosilicate. The base color is dark green, with red points on it. The name heliotrope is derived from the Greek helios, which means sun and trepein, "spin". The classic source of heliotrope is the Kathiawar Peninsula in northwest India. Nowadays it is also won in Brazil and Australia.
