Yellow Opal Children's Bracelet in 4 mm
Opal
Opal is an amorphous form of silica with variable water content. Within opals, a distinction is made between precious opal, which is known for its play of colours (opalescence), and ordinary opal, which does not show this effect. Common opal occurs in various colours such as white, pink, blue, green or brown, usually with a waxy to glassy luster.
Major deposits include Australia, Peru, Mexico, Brazil and the United States. Its chemical formula is SiOâ‚‚-nHâ‚‚O. Common opal often forms in volcanic or sedimentary environments. Its hardness is between 5.5 and 6.5 on the Mohs scale.
Well-known varieties include pink Peruvian opal, green opal, Black opal and dendritic opal, which are distinguished by their unique colour and inclusions.

Pyrite
Pyrite, also known as "fool's gold", is an iron sulphide known for its metallic luster and golden-yellow colour. It often forms cubic or pentagonal dodecahedral crystals and occurs in a wide range of geological environments. Due to its appearance, pyrite was frequently mistaken for real gold in the past, although it has a very different composition and hardness.
Pyrite is found worldwide, with important deposits in Spain, Peru, Italy, the United States and China. It occurs in magmatic as well as sedimentary and metamorphic rocks. Its chemical formula is FeSâ‚‚ and its hardness is 6 to 6.5 on the Mohs scale.
