Jewelry is the art of transforming precious metals and stones, especially gold, into works used as jewelry and investment tools. The first thing to do when buying a jewelry product should be the query of the materials used on it. If you want healthy shopping, it is always the right of the buyer to ask what material the purchased product is made of and what kind of stones are used. So what about the price of the jewels? Which jewelry is the most expensive?

Diamond jewelry is the most expensive jewelry among all others. The fact that it takes many years to form, is difficult to extract, is rare, requires effort to be processed due to its hardness, are the reasons why diamonds are the most expensive jewels in the world. It has maintained this feature for centuries. Although it is thought that the value of the raw diamond decreases during the transformation into diamond, this situation is not as expected. The raw form of a diamond is not as eye-catching as a jewel diamond. It is the stage cut that makes it radiant and magnificent. The shape is an important issue that directly affects diamond prices.
Why Diamond Is the Most Expensive Jewelry?
The diamond, which is often thought to be expensive because it is scarce, actually has a very interesting story. As a matter of fact, diamond is one of the most mined and therefore the least rare gems among precious stones. So why is the diamond valuable? Why is diamond expensive compared to other precious stones? First of all, it is worth noting that. Diamond was also a very precious stone in the past. The ancient Greeks believed that this indestructible stone had magical powers, thus conferring status to its owner.
Royals and nobles took great pleasure in wearing diamonds. So diamonds are not a new phenomenon. Over the years, the diamond has been a symbol of power and wealth. It used to be enough to explain the rise in the rarity price as diamonds were much harder to find, but that’s not the case today.
In the 1800s, a new diamond mine was discovered in Kimberly, a South African city. This mine, which has enough diamonds to meet all the diamond needs of the world, had enough potential to quickly reduce diamond prices. Seeing this, a company called De Beers intervened immediately and bought the mine. Running the world’s largest diamond supply unchecked shouldn’t be a huge waste of money. De Beers has controlled the mine’s diamond supply just enough to keep prices at a level. For this reason, diamonds were still thought to be rare and their prices did not decrease.

By the 19th century, De Beers had become a worldwide monopoly and taken control of the mines. One of the smartest moves by De Beers was to support the trend of making marriage proposals with a solitaire diamond ring. While emerald and sapphire rings were popular before, the new campaign has increased the demand for diamonds. Therefore, the reason why the diamond is expensive is not that it is rare, but because it is a perception operation carried out on the assumption that it is rare. Diamond is not a rare metal, but when the features such as its very hard, almost unbreakable structure, and the fact that pure diamond emits a tremendous light under the light, the work of those who carry out the perception operation was not too difficult.
The price of diamond rings depends on the quality of the diamond used and its craftsmanship. When the brands’ own dividends are added to this, the prices of diamond rings are in a wide range. For example, a 0.04-carat diamond solitaire ring can cost between thousand and 2,000 USD, while a 3-carat solitaire diamond ring is sold for around 400 thousand USD. The size, purity, cut and color of the diamond directly affect the price of the solitaire. Solitaire rings in the examples above can cost twice as much when using a colored diamond.
The most expensive diamond solitaire ring ever sold is made of a very rare blue-colored diamond. A billionaire paid 48.4 million dollars to buy a 12.3-carat diamond ring, called the Blue Moon, as a gift to his 7-year-old daughter, with its perfect color and light quality.
Which Factors Affect the Price of Diamond?
Of course, no diamond has equal features; like any commercial product on the market. Many factors, from its shape to its cut, from its color to where and how much it is found, play a major role in the pricing of the diamond. That’s why we would like to summarize the features that affect the price of the diamond in 5 items in order to clear our confusion and follow a more conscious way in diamond shopping.
Almost all of us have heard of the 4Cs of a diamond in some way. For those of us who haven’t heard, what is this 4C? The four words that start with the letter C, cut, clarity, color, and carat, are values that reveal the rarity of a diamond according to its level. This 4C reflects the unique characteristics of each diamond and is valued in the diamond sizing system.

Most diamonds sold in the market are certified by official institutions. HRD Antwerp (Antwerp Diamond Supreme Council) and GIA (American Gemstone Institute) are the most reliable and prestigious diamond certification bodies known; Apart from these, there are other institutes as well. These institutions have very systematic and consistent measurement methods, and this proves whether the diamond you bought with peace of mind is in the specifications you have been told. For this reason, buying a certified diamond always gives you value for your money.
In the diamond world, cutting is the surface (i.e. faceting) of the rough diamond with angled cuts and shaping it to reflect light in the strongest possible way, creating sparkles and colorful flashes of light. Ideally, there are 57 facets on the diamond. The diamond consists of 3 parts; crown, belt, and cone. The crown has 33 facets, and because the number of facets is more in this section, more flare appears. The belt section under the crown also affects the shine of the diamond. If the belt thickness is too much, the light will be kept and the diamond will look dull; however, if it is too thin, the stone may break while being set.
The part under the arch is called the cone and has 24 facets. The cone allows the light entering the diamond to reflect out. The more accurately the cone is cut, the light entering the diamond is reflected, leaving the crown again, and optimum brightness is achieved. The proportions, angles and systematic arrangement of the sections are intended to reflect the light in the deepest way. Sometimes a diamond with a very high level of color and clarity cannot be cut incorrectly; therefore, it may cause it not to shine and may cause depreciation in terms of price.
Again, diamond grading institutes evaluate the diamond’s ability to reflect light while certifying it. There are 3 main factors that affect the cut of the diamond; A well-cut diamond should have symmetrical facets, equal proportions of the facets, and the stone should not be cut too deep or short.
Although the most known cut in terms of shape is the round cut, there are also different cuts called fancy cuts in the diamond cut. A round cut diamond is more expensive than many cuts because more rough diamonds are chipped and crafted. In other words, in order to cut a round cut diamond, a larger bit of diamond is required. On the contrary, diamonds that use less raw materials, such as princess cut and emerald cut, might be more affordable.

As we mentioned before, like almost everything found in nature, diamonds are unique in many ways as a miracle of nature. No diamond is the same with the features it contains; clarity is the feature that highlights this most strikingly. Stains, marks, air bubbles, cracks, and clouds found in a rough diamond are called inclusions (residue, foreign matter) and nowhere are two diamonds with the same inclusion. How few of the inclusions mentioned are in the diamond; In other words, the clearer the diamond, the more valuable the diamond becomes. Inclusions are graded by size, number, location, natural feature, and area; This, combined with other factors, creates a criterion for pricing.
Although diamonds seem colorless to the naked eye, every diamond has color except the rare ones, and it is formed in different colors due to the reactions of the diamond. When gemstone experts talk about the color of the diamond, they are actually talking about how colorless it is, and the fewer colors the diamond has, the more valuable it is. It usually has colors in diamond yellow and light brown tones. The rarest and nearly colorless ones are designated by the letters D, E, F, G. The majority of the diamonds in nature are between H and L colors, and this sequence continues by coloring up to Z. Apart from this, there are also rare diamonds with clear colors such as very rare pink, blue, true yellow and red.
Carat is the unit for measuring the mass of a diamond, weighing one-fifth of a gram, and abbreviated as ct (1ct = 0.200 g). In fact, although the carat is thought to be the most valuable factor that determines the price of a diamond when the factors mentioned above are taken into account, the carat weight alone is not enough for a diamond to be expensive.
