[vc_row][vc_column width=”2/3″][vc_column_text]A diamond is composed of pure carbon crystallised and is the hardest substance known. Only Mother Nature can make a natural diamond. A natural diamond is identified using only the single word, “diamond”. Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometres in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).
Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites.
Diamonds have been mined as long ago as 800B.C however, they were not discovered in Africa until 1866 Now, Roughly 49% of diamonds originated from central and southern Africa, although significant sources of the mineral have been discovered in Canada, India, Russia, Brazil, and Australia.[/vc_column_text][/vc_column][vc_column width=”1/3″][vc_single_image alignment=”center” border_color=”grey” img_link_target=”_self” img_size=”full”][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_custom_heading text=”We believe here at Robert Cliff Master Jewellers you should know what you are buying!” font_container=”tag:h2|text_align:center|color:%2321759b” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal”][vc_column_text]Buying a diamond is an exciting process but can also be very confusing. Scientific and technological advances in the jewellery industry have made it possible for synthetic diamonds to be manufactured and laboratory-created (made by man). There are even some very good imitations – just know what you are buying.[/vc_column_text][/vc_column][/vc_row]
