There really is not such a thing as an average price for a diamond as such. Diamonds are priced by 4 factors (the 4 Cs)--cut, clarity, color, and carat (weight). Cut refers to how well the diamond is cut. Clarity refers to the internal flaws the diamond might have. The more flaws the less it is worth. Color refers to the color of the diamond. A white diamond is worth considerably more than one that is yellowish. Finally carat weight refers to the size of the diamond. The bigger the diamond the greater the price. You are asking for an average so if we assume an average cut, average color, average clarity, and a smaller size carat weight assuming more of those are sold than of the larger diamonds and if we assume just the diamond and no setting, then we can perhaps give you a rough idea of what the price might be. Certainly, the most popular clarity would be one with very slight imperfections. The color of the average diamond would probably have some slight color when compared to a colorless diamond probably a J or I color. Cut would be good to very good rather than ideal. Let us then assume a 0.5 carat diamond, J or I color, very good cut, with very slight imperfections. Blue Nile sells these diamonds for about $1100 to $1300 each.
What you have to sell is worth whatever someone will pay you for it. In October 2012, there were diamonds of about this weight sold at the Christie's sale. You can read more about the sales, below. In particular a diamond weighing just over 50 carats sold for US$9,500,000. In a ring, the mounting would be an additional cost.
Back in the 1950s engagement rings ranged in price from a few hundred dollars and up depending on the style, diamond size, and metal type. Remember, this period was shortly after the war, and money was tight. A small diamond (.15 carat) solitaire white gold ring would cost around $100 at that time. A ring with a .25 carat stone done in platinum would cost roughly $300 to $400. Any ring that was a filigree setting or had accent stones would cost more, due to the workmanship and additional stones.
Generally, yes. From MostExpensive.com: "The world's most expensive diamond sold for $24.3 million, beating a previous record of $16.5 million for a 100-carat diamond in 1995. While the [35.56 carat] Wittelsbach is the most expensive diamond ever sold at auction -- and likely the most expensive diamond ever sold, period -- the world-famous Hope diamond [of about the same colour] would no doubt put the Wittelsbach to shame were it ever sold." Read more about this stone, below. On a more realistic level, because diamonds are so valuable, most people who own diamonds -- and other precious gems -- insure them against loss. Buying a diamond is a major purchase and often a major investment. Unlike buying a car, for example, that can end up scrapped in a junk yard over time, a diamond will always maintain its (gemologist's appraised) value.
Any revalue of diamond would be based on the market for that particular diamond.
A 4 carat diamond ring would be ridiculously expensive. In the $100K mark I would expect. If someone is showing you their 4 carat engagement ring, it is probably cubic zirconia.
Carat is the measurement of a diamond's weight. The stone's value would partially depend on its carat weight.
A 625 carat diamond would be a very large diamond, weighing 625 carats.
It would depend on the quality of the diamond. Obviously a quarter carat is smaller than a third but if the third carat is of poor quality and the quarter is superior quality then the quarter would be worth more.Another AnswerEvery diamond is valued by its carat weight, its colour, its clarity and its cut.
A 2 carat diamond cushion cut ring would make a beautiful engagement ring. The price of such a ring would vary from jeweler to jeweler; however, one could expect to pay from around $450 upwards.
Generally, you would write .50 carat to represent a half-carat stone.
For a complete answer, you must go to this site:RarityOf the 4 C's, Carat Weight is probably one of the most important considerations with respect to rarity, value, and consumer preference. In fact, Carat Weight, or how much the diamond weighs is the most significant value factor in a diamond. Because diamonds by nature are rare, a 2 carat diamond is actually about 3 times more valuable than a comparable quality 1 carat size. Statistically a 1 carat is one in a million diamonds mined, and a 2 carat is one in five million diamonds mined. Therefore, all things considered a 2 carat diamond is really "value priced" based on the rarity factor.PricingLarger diamonds are much more rare, thus commanding a higher price/per/carat. Carat weight affects the value of a diamond by about 10-20% for each step in size difference. Also, "magic sizes" refer to major carat weight categories, for example exactly 1.00 carat, or larger, and can prompt "price premiums". To calculate the price of a diamond you multiply the carat weight by the price/per/carat. For example: if a 1.25 carat diamond was priced at $10,000 per/carat the diamond would be sold for $12,500.* http://www.diamonds.com/education/Carat.aspx
Yellow gold would provide the highest contrast value as a background for a 1 carat diamond.
If the diamond is cut, 4-point may refer to its weight, would would otherwise be expressed as .04 carat, or 4/100ths of a carat.
Diamonds are measured in CARATS. Purity of gold is in KARATS. A 14 carat diamond would be an extremely large diamond- about the size of a marble. Value is based on carat weight, cut, color, and clarity- but that would be a multi-million dollar stone in all likelihood. But I think you are looking at marking of the metal.
Any diamond is valued by its cut, clarity, color and carat weight. A large stone such as this would be very valuable, given its size alone, which is uncommon and rare. But a fixed price can't be calculated without the other details.
