Most natural diamonds have ages between 1 billion and 3.5 billion years. Although a few have come from depths as deep as 800 kilometers (500 miles) in the Earth’s mantle, most were formed between 150 and 250 kilometres (93 and 155 miles) in the Earth’s mantle. As a result of carbon-containing fluids being subjected to high pressure and temperature, various minerals were dissolved and replaced by diamonds.
Diamonds of gem quality are mainly located below cratons in mantle keels, the thickest part of the lithosphere. These depths occur beneath cratons in the mantle keels, which are the thickest part of the lithosphere. Diamonds can be stored in these regions for billions of years until a kimberlite eruption samples them, because they have a high pressure and temperature in these regions that allow diamonds to form and are not convecting.
A diamond is a hard and brittle stone that can be split in half by a single blow. That is why diamonds can be transformed into gems in a multi-step process called “cutting”. As a result, the cutting of diamonds is traditionally regarded as a delicate process requiring the use of a number of skills, scientific knowledge, tools, and experience.
It is the preliminary analysis of the rough stone that is the most time-consuming part of the cutting process. Due to the high number of factors involved, this analysis carries a great deal of responsibility and can often take years to complete, especially in case of unique diamonds.
