Because they're rare. Nothing else.
Sometimes. Diamonds can come in a variety of different colour. Pink diamonds are actually among the world's rarest and most expensive diamonds.
Yes, vivid blue diamonds are generally rarer and more expensive than vivid pink diamonds due to the unique geological conditions required for their formation, as well as the consumer demand for blue diamonds. Blue diamonds are highly sought after for their rarity and distinct color, often commanding higher prices than pink diamonds of similar quality.
Yes, blue diamonds are generally more expensive than white, pink, or black diamonds. This is due to their rarity, with high-quality blue diamonds being quite scarce compared to other colors. The unique coloring of blue diamonds adds to their allure and value in the market.
Pink diamonds are the rarest and the most expensive of diamonds in the market. Prices can run into the millions due to their rarity. An affordable alternative is pink sapphires which many jewelers recommend.
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
Diamonds are not sold by centimeters, but by caret, color, quality. Pink diamonds have a tendency to be expensive. I suggest a pawn shop might give you a good value.
Generally pink diamonds are found in Australia. Australia's Argyle mine, in far north Western Australia, produces around 90% of the world's supply of pink diamonds. These are the world's only "intense" pink diamonds. Pink diamonds, one of the most rare and expensive diamonds in the world, are also mined in India, Brazil and Africa, but these are lighter in colour.
Given the same carat weight, clarity and cut, you will pay more for a pink diamond than for a 'white' or colourless diamond.
Natural pink diamonds are more rare than natural yellow diamonds, probably because the common trace element nitrogen is responsible for a yellow cast in a diamond. Some colourless or 'white' diamonds are considered yellow, when graded with a colour grade from I to Z, as below. Natural pink diamonds exist 'due to structural anomalies" according to Wikipedia, and are very rare. Some diamonds can be altered (or enhanced) to appear yellow or pink, and when altered, are less valuable than naturally colored diamonds.
Any pink diamond is known as a pink diamond, and its description may include 'fancy', 'intense', 'light' and so forth. Pink diamonds can also be described as pink-purple, and more. You can follow the link below and find three important pink diamonds in the list.
Black diamonds that are available in the market are usually low grade white diamonds that have been colored black, however, natural black diamonds can be expensive depending on the quality.
Yes, if they are natural diamonds. Diamonds can be treated or enhanced to 'bring out' a colour, so a faint pink diamond could be treated to enhance the colour and become a more intense pink. Enhanced diamonds are of a lesser value than naturally coloured diamonds. Today, most natural pink diamonds are produced from the Argyle mines in Australia, and are pink based on "...low levels of nitrogen impurities, their colour resulting instead from structural defects of the crystal lattice," according to Wikipedia.
