Fred Meyer Jewelers carries Canadian Ice diamonds; a popular choice for wedding rings, especially solitaires. The diamonds are mined from the Diavik mine in Canada's Northwest Territory.
Diamonds are formed deep in the ground, in the mantle, below the crust of the Earth. They are a high concentrated form of carbon that have been introduced to extremely high temperatures and pressure. Diamonds are naturally pushed to the surface of the Earth in molten rock found in volcanoes. Erosion around the volcanic "pipes" can lead to the discovery of diamond deposits. Industries mine for diamonds in areas rich with volcanic rock. Kimberlite and Lamproite are the two kinds of rock that diamond deposits can be found in.
