The Trésors d'Afrique exhibition presents the third and final destination for the collection The Worlds of Chaumet.
Gold is a symbol of light and eternity. It is unalterable and does not react with air, water regardless of temperature, or acids. With a hardness of 5 on the Mohs scale, it is malleable enough to be easily worked by drawing, rolling or casting, into leaf form, strands or round grains.
Gold can be enamelled, inlaid, engraved and embossed. It remains unchanged even melted several times. It can be combined with other metals to change its colour, increase its strength or influence its hardness... Gold has a verifiable qualification expressed in either carats or fractions using the decimal system, in parts per 1000.
Pure gold without alloys is 24 carats. As this is too soft (hardness 2.5 to 3), it is alloyed with other metals to harden it. A hallmark is stamped onto all the gold jewellery, certifying 18 carat quality.
