Diamonds. Monday , January 16th , 2017 - 14:59:55 PM
Diamonds are formed under tremendous heat and pressure. These conditions exist at about 150 to 200 km beneath the Earth's surface, where the temperatures are extremely high ranging from 900 C to 1300 C. For millions of years, carbon atoms deep in the Earth's upper mantle have been exposed to these extreme conditions. As a result, these atoms combine their cubic molecular form, and they ultimately form diamond crystals. During volcanic eruptions, these crystals eventually make their way to the Earth's surface through pipes and channels. These passageways contain the magma from the volcano, which rises along with the diamonds, and deposits them on the surface where they are later found and mined. These are known as the primary deposits of diamond. The igneous rock called kimberlite is the most common host of diamonds found in the earliest volcanic pipes.
Preservation: At times when you have an antique or a vintage ring that you want to clean up and help it get back its old charm, then remounting is a good option.
In a channel set diamond ring a row of diamonds, usually round cut or baguette cut are held together by two tracks of metal. This style of diamond rings are preferred by women who likes a sophisticated design but does not want to compromise on the bling factor.
