Yellow gold ring 750‰ with white diamond

What is Yellow Gold?

Gold is a malleable, noble metal with a shiny yellow color that is found in nature. To obtain yellow gold, an alloy of gold, silver, copper, and zinc is created. The alloy of these different metals fused together gives the typical yellow coloration of yellow gold jewelry. Its purity is measured in carats, which indicates the amount of pure gold contained in a piece of jewelry: the jewelry Comete is made of 18-carat gold or 750 ‰ and therefore consists of 750 ‰ pure gold and the remaining 250 ‰ from other metals.

What cut of Diamonds does Comete use?

Comete in its jewelry prefers the brilliant cut, the cut that most enhances the brightness and luster of all precious stones.

What purity do the Diamonds Comete have?

Our jewelry primarily uses diamonds of SI Clarity and G Color. Often, diamonds have some tiny imperfections inside them, called inclusions. The clarity scale ranges from F (Flawless = free of imperfections) to I (Included = inclusions). Therefore, SI Clarity for a diamond establishes how many tiny imperfections the diamond has, based on the clarity scale. In this specific case, SI is the abbreviation for Small Inclusions and applies to diamonds whose inclusions are small but visible with a 10x magnifying glass.

What is the Diamond?

Diamonds originate in the Earth's mantle, where the extremely high pressure conditions necessary for their formation exist. The crystals are brought to the surface, embedded in a rock containing a lot of olivine called kimberlite, by volcanic conduits through eruption. This gives rise to the diamond pipes of primary deposits. Subsequently, through erosion, kimberlite can be broken down, releasing diamonds into secondary deposits, generally of alluvial type.
