Colored diamonds are created both naturally in the ground over thousands of years and artificially in a lab using technology to treat uncolored diamonds. Naturally created colored diamonds are rare and expensive, while artificially created diamonds cost much less and are regularly available at jewelry stores.Know More
Naturally colored diamonds are created deep within the earth by different forces. High heat during the compression phase of rock formation and the introduction of other elements, such as hydrogen, boron and nitrogen, in the usual carbon chain can create many different colors of diamonds, while radiation deep within the earth is known to create blue- and green-colored diamonds. The most common naturally occurring colored diamonds are black, gray and brown, while the most rare are red, purple and orange.
As of 2014, the general price of naturally colored diamonds ranges from $2,500 to $1,500,000 per karat. The type of color, vibrancy of the color and size of the stone all affect the price of a naturally occurring colored diamond.
Artificially created diamonds are created in a lab and use technology to turn diamonds with a yellow or brown tint into colored diamonds. These diamonds are exposed to radiation and high-heat in order to produce different colors. This process creates blue, purple, yellow, green and other color diamonds for purchase at a more affordable rate than that of naturally occurring ones.Learn more about Precious Metals & Gems
Natural diamonds typically come from inside the Earth’s mantle. They form when carbon deposits are acted upon by a combination of high temperatures and pressure. Formation of a diamond from carbon requires one to 3.3 billion years, and they rise in magma to near the Earth’s surface through volcanic action. Once the magma has cooled into igneous rock, the diamonds can be mined.Full Answer >
Natural diamonds are formed deep within the earth, using heat and pressure found around 87 to 118 miles beneath the surface. Carbon compressed tightly together forms a crystal lattice, the purity of which determines colors in the diamond.Full Answer >
A common process for mining diamonds is to remove and process kimberlite ore. Kimberlite ore can be found in underground mines and open pits and often contains a small amount of diamonds that must be separated from the ore. The process of mining can require several months or longer, depending on the size of the mine.Full Answer >
On a carat for carat basis, rubies are worth more than diamonds of similar size and weight. The reason that rubies are more expensive is the fact that it is much rarer for rubies to be found without faults than it is to find a flawless diamond.Full Answer >
