Even so, you might spend more on genuinely unique gems. We’re sure you’re wondering why the prices are so high.

To best understand the answer we have given you, we think it is essential to explain to you what diamonds are, how they are created, how and why their price is formed, why it is often so high, and a lot of other exciting things.

Let’s start from the very beginning!

Diamond, Their Characteristics, Worth, and Many More

To help you better comprehend the qualities of diamonds, let’s start with their value, price, and worth!

A diamond is a solid form of the element carbon, with its atoms arranged in a crystal structure referred to as the diamond cubic crystal structure.

Although diamond progressively changes into it, graphite is another solid form of carbon chemically stable at room temperature and pressure.

Diamonds have exceptional hardness, unmatched brilliance, and significant emotional value.

They are the only other substance that can scratch their surface, even though they are virtually entirely composed of carbon atoms.

Let’s examine how diamonds are made now that we have defined a diamond!

Since diamonds are made of carbon, they start as carbon atoms that join together under extreme conditions of pressure and heat to form crystals.

Simply put, the formation of diamonds occurs when the earth’s deep carbon reserves, which are found 90 to 125 miles below the surface, are subjected to extremely high temperatures and pressures.

Some stones develop over millions of years, while others do it in days or months.

In addition to its hardness, diamond possesses an astounding range of chemical, physical, and mechanical properties.

  • Low coefficient of friction.
  • Significant thermal conductivity.
  • Significant electrical resistance.
  • Low thermal expansion coefficient.
  • Strong.

There is extensive optical transparency ranging from ultraviolet to infrared. Diamonds are carbon. Thus they start as carbon atoms that bond together at high temperatures.

Diamond sizes are measured in millimeters (mm). These measurements are about the size of carats.

A 1-carat round diamond typically has a diameter of 6.5 mm, whereas a 1.25-carat diamond has a diameter of 6.8 mm.

A square-cut diamond with a weight of 1 carat, like a princess or cushion, typically measures 5.5 mm, whereas a 1.25-carat measures 6 mm.

Diamond production is declining as mines reach the end of their productive life.

So your question must be, why are diamonds so expensive?

Diamonds are expensive because of their high marketing costs, lack of exceptional grade stones, and great demand.

Let’s now focus on the factors that affect the value of a diamond!

What Factors Affect the Value of a Diamond?

In general, a diamond’s rarity determines its value. The following factors influence rarity and, consequently, value:


The weight of a diamond is measured in carats, which is a reasonably accurate unit. Diamonds with a high carat weight are more expensive since big diamonds are uncommon.

However, a tiny carat does not necessarily indicate low quality in a diamond. Even a diamond with a relatively low carat weight can be flawless and have a brilliant cut.


The quantity of “inclusions” (internal marks) and “blemishes” (external influences) that a diamond has is referred to as clarity.

A rating scale is used to quantify this. When a diamond is classified as “Flawless,” no flaws or imperfections can be seen at a magnification of 10 times.

At the opposite end of the spectrum, “Included 3” denotes inclusions that are sizable enough to impact the diamond’s clarity.

“Flawless” diamonds are scarce since they are made under extremely high-pressure underground, easily damaging both the inside and outside of the diamond. However, they are precious as a result.

Diamonds must be well cut to dazzle brilliantly. The objective of a diamond’s “facets,” which are its cut surfaces, is to reflect as much light as possible.

A professional craftsperson who can determine the optimum approach to cutting each unique diamond is needed to do this task.

This is why getting your diamond necklace from a trusted vendor is crucial. Even the most stunning stone might become dull if a diamond is cut improperly.

Colorless white diamonds are the most expensive. Yellow-tinged diamonds are more prevalent and viewed as being less valued.

But infrequently, “fancy-color” diamonds are found, and due to their scarcity, they are costly. They come in shades of blue, red, or green.

Does The Value Of Diamond Necklaces Rise With Time?

Diamond necklaces generally appreciate value over time. However, several variables affect how quickly this occurs.

What Is The World’s Priciest Diamond Necklace?

You were, for sure, wondering what is the most expensive diamond necklace. Let’s find out!

A Heritage in Bloom is the title of the most costly diamond necklace in existence right now. A 507.55-carat diamond known as the Cullinan Heritage was purchased by the Hong Kong jewelry business Chow Tai Fook in the middle of the twenty-first century.

Wallace Chan, a renowned Chinese jeweler, was hired to utilize it to make a necklace.

A Heritage in Bloom includes eleven thousand five hundred fifty-one jewels totaling white and pink diamonds, white mutton fat jades, and jadeites.

It uses Chinese symbols such as butterflies and bats for love and wealth. To honor the significance of the number 27 in China, you may even wear the necklace 27 in various ways.

Each white diamond in the necklace was cut from the Cullinan Heritage, making this one of its most distinctive aspects.

The biggest gigantic diamond ever found was unearthed in Pretoria, South Africa.

Given that the necklace is deemed to be “Internally Flawless,” this considerably increases its worth. This implies that even if the diamond’s outside had nicks or flaws, its inner would still be immaculate when examined under a microscope.

While the necklace overall is valued at $200 million, the 104-carat center stone is only worth $35 million.

Are there benefits of investing in diamonds? Let’s take a quick look!

The Benefits of Investing in Diamond Jewelry

The use of diamond jewelry as an investment strategy has rapidly increased over the past several years.

Compared to gold, it is a better investment due to several features.

Size: Its size is the first and best advantage over gold. Diamonds are much smaller than gold bullions and take much less space.

Since ancient times, these priceless diamonds have been an excellent way of transferring money.

No matter how little, a diamond trinket costs twice as much as gold jewelry of the same size. This implies that diamond jewelry, such as necklaces or bangles, makes ideal investments.

Also, storage capacity is excellent when something is little. So much so that even a modest safe may contain a diamond worth thousands of rupees.

Diamond jewelry is another investment that may be seen, held, and worn. Many believe it to be a safer investment than stocks and other digital assets as a consequence.

Durability: Another benefit that diamonds have been endowed with nature is their durability.

It is the most challenging thing to do on Earth. You may be confident that it won’t suffer any harm.

As long as you take proper care of your diamond jewelry, you won’t have to worry about it fading. This implies that you may use and enjoy your investment for as long as you choose.

Additionally, you may insure it if you are concerned about losing it. Like other tangible goods like gold, silver, and real estate, diamonds are likewise immune to inflation.

However, diamond jewelry is a more transportable and long-lasting investment than other tangible goods.

Jewelry made from diamonds has financial advantages in addition to the psychological and physical factors that make them desirable investments.

What Are the Risks and Cons of Buying Diamond Jewelry?

Only the market, based on supply and demand, determines the price of diamonds.

Lack of traceability is the second danger of purchasing diamonds as an investment. Diamond jewelry purchases are simpler than diamond sales. Some businesses purchase them, but their demands will be below the cost you paid.

Long-term advantages: Which of the drawbacks of purchasing diamond jewelry is the most difficult to overcome?

To gain from it, you must have patience. Diamond jewelry is not a good choice if you are searching for quick profits or making a short-term investment. You can include them in your long-term investment portfolio if you are willing to wait for the profits.
