The meaning and history of the birthstone diamond go back many years, to ancient India, when diamonds were highly valued as sacred stones that represented power and purity.

In ancient India, diamonds were believed to possess mystical powers and were often worn by warriors for protection in battle due to their association with strength.

Diamonds were viewed as a symbol of purity and perfection in various cultures across the globe, representing everlasting love and commitment.

Throughout history, diamonds have been prized not only for their beauty but also for their durability and rarity, earning them a reputation as the ultimate symbol of luxury and prestige.

Ancient Beliefs and Customs

Modern Significance

In modern times, diamonds have become synonymous with love and commitment, especially through the marketing efforts of De Beers and the tradition of using diamonds in engagement rings as symbols of eternal love and marriage.

This symbolic connection dates back to the late 1940s when De Beers launched its iconic slogan ‘A Diamond is Forever’, reinforcing the idea of everlasting love encapsulated in a diamond. The brilliance and durability of diamonds have since been associated with the enduring nature of relationships, making them the perfect choice for symbols of eternal commitment.

Engagement ring culture has been shaped significantly by this marketing strategy, with diamonds being positioned as an essential component of the proposal process.

secrets about diamonds

Check if a diamond is natural with your breath.

Place the diamond near your mouth and fog it with your breath. A natural diamond will not get fog up quickly. When it is fogged for a couple of seconds, then it is probably fake.

Check if a diamond is natural with a magnifying glass.

magnifying glass

If you have a magnifying glass or can ask to give it to you, you can check the stone with it. Take a look at the mirror and look for imperfections. Natural diamonds have flaws; fake ones or lab-created ones don’t. Sometimes, a genuine diamond has no inclusions, but it will be too expensive.

Or you can examine the diamond with a loupe, like the ones that jewelers have. Inspect the stone for imperfections or color changes. Usually, they have, which means the diamond is natural. There is always the possibility that you are seeing a flawless diamond. In that case, check for a certificate or ask a professional.

Diamond Cut

Nature determines the color of the diamond, but man is responsible for showing true beauty with the cut procedure.

Only professionals can bring the diamond from its natural appearance to a piece of art.

The most crucial factor is the diamond cut. This means how much the stone shines or how much it sparkles.

The surfaces of the diamond and how well they are distributed are the cut factors.

Diamond Cutting techniques.

There are many shapes and cutting techniques; the most popular is the Round Brilliant, mainly because it reflects the light the best. Find ten facts about diamonds and diamond cutting at

According to the GIA (Gemological Institute of America), the scale is Excellent, Very Good, Good, Fair, and Poor.

These are the characteristics of a diamond cut.

  • The brilliance. How much reflects the white light?

When you buy a piece of diamond jewelry.

Most people, when buying diamonds, ask for the carat value. The most crucial factor that determines the price is the diamond cut.

An excellent diamond cut is the most expensive. This is because the diamond optimizes the light more and has superior sparkle.

Diamond Color

Diamonds come in all natural colors, like light yellow, grey, white, green, and brown. The diamond color means the absence of color. It is rare to find a diamond without any color.

The color scale grade

The color scale D to Z is the industry standard for color rating diamonds. D means colorless, while Z means a light color. To put it simply, a D-grade color diamond is the most valuable. So, the price decreased alphabetically, going up to Z.

Secrets about Diamonds and Color

  • Only a certified gemologist can color-grade a diamond.
  • Color is more visible in bigger diamonds.
  • At the GIA laboratory, diamonds are colored grade, compared with masterstones (diamonds known color).
  • When diamonds are exposed to Ultraviolet (UV) light, they emit fluorescence.

A test for our viewers reading secrets about diamonds. Open the above image in a separate tab and find any color inside the diamond.

Leave a comment below. Let us see who is the first with the correct answer.

Diamond Clarity

Diamonds are made inside the Earth under extreme circumstances. Pressure and heat create minor imperfections.

These imperfections are the reason for the diamond clarity grade.

If the flaws are inside the diamond, they are called inclusions. If they are on the surface, they are blemishes.

Inclusions are also called internal characteristics because they give the diamond its character.

Secrets about diamonds and clarity.

  • Diamond clarity is one of the four essential characteristics of a diamond. Clarity will affect the price, but it also affects the beauty of the diamond.
  • Big-sized diamonds have more impact on diamond clarity. Also, the shape of the diamond, like the fancy ones, needs a higher clarity grade.
  • When the inclusions are too small to see with the naked eye, we call the diamond “eye clean.”

Diamonds clarity category grades

  • Included Diamonds. (I1 to I3). The lower category means the inclusions are visible to the naked eye.
  • Slightly Included Diamonds. (SI1 and SI2). Inclusions are noticeable with magnification.
  • Very Slightly Included Diamonds. (VS1 and VS2). Minor inclusions are noticeable with magnification—great value over price.
  • Very, Very Slightly Included Diamonds. (VVS1 and VVS2). These diamonds have inclusions that are very difficult to see, even magnifying. These are rare diamonds and follow an eye-clean appearance.
  • Internally Flawed Diamonds. (IF). Some blemishes (on the surface) are visible on a microscope.
  • Flawless Diamonds. (FL). A perfect natural diamond is rare because it has no internal or external characteristics.

Different types of diamond characteristics.

Inclusions can be knots, feathers, clouds, cavities, or crystals

Blemishes can be scratches, breaks, nicks, or pits.

Never buy a diamond under stress. It is better to be late than sorry.

Diamond Carat.

Diamond carat refers to its weight, not its size.

This is one of the reasons why we created the article “Secrets about Diamonds.”

Every carat (ct.) weighs 0.2 grams of a diamond or 200 milligrams. Each carat is divided into 100 points.

That means if a diamond is 1.13ct, it is called “1 carat and 13 points”.

Secrets about diamonds and carats.

  • It is essential to say that diamonds of the same weight do not necessarily have the exact sizes.
  • When diamonds are mined, small gems are discovered more frequently, which is why the large rocks are more valuable.
  • Diamond prices rise logarithmically with the carat weight. For example, a diamond of 1.5 carats is worth more than two diamonds of 0.75 carats when they are both of the same quality.
  • Remember this. The diamond value is determined by all four significant values: cut, color, clarity, and carat weight.
  • When you buy a piece of diamond jewelry, you may hear the term “tw.” That is the total weight of the diamonds in the jewelry.
  • As we already said, carat weight is not the same as the size. That is why the shape of a diamond is not the same.

Diamond certification is when a gem laboratory tests and assesses the quality of a diamond.

The lab creates a written report or certificate that remains in the archive, and a copy is sent back to the diamond owner.

Every certificate has its number that can be inscribed on the diamond with a laser. This proves that the specific diamond is graded, and even with the certificate lost or stolen, it is easy to find it again from the records.

Secrets about diamonds and certifications.

  • Documents or appraisals from any jeweler are not counted as certifications. Gem labs use special equipment to grade each diamond.
  • Some diamond certifications issue a plot of the diamond. This is a map or drawing of the diamond inclusions (internal marks)
  • We are talking about natural diamond certifications. Find later in the article about lab diamonds.
  • You can prove the diamond’s grade when you want to resale a diamond.
  • Verify your diamond in case of repair or insurance.
  • The US Government legally permits jewelers to sell diamonds to be off by one color and clarity grade. That means you can pay a significant amount more. Never buy an expensive diamond without certification.

Secrets About Diamonds. Lab-Grown Diamonds.

Natural diamonds form underneath the Earth over a billion years, under tremendous pressure and heat. Lab-grown diamonds are created in a Lab in a few weeks.

There is also a chemical difference. Natural diamonds may contain little nitrogen, but lab-grown diamonds don’t. That is the only difference between the two.

Even the FTC (or Federal Trade Commission) classes artificial diamonds as accurate due to the gem’s chemical makeup.

Scientific facts about diamonds. Lab versus Natural.

Ten scientific facts about diamonds

  • Lab-grown diamonds are cheaper by about 35% compared to natural ones. This year, because of the ample supply, the difference is more. We could find 50-65% more affordable prices when comparing same-quality diamonds.
  • Natural diamonds are always a good investment. They have great value over time.
  • Lab-grown diamond prices have dropped by 70% in the last two years. The reason is because of new technologies and the supply is more significant. On the other hand, the natural diamond supply is the same, so prices are not fluctuating.
  • Lab-grown diamonds’ resale value is minimal to none. At the same time, natural diamonds’ resale value is about 50%.
  • Gcal (Gem Certification & Assurance Lab) is one of the certification labs for lab-grown diamonds. Their report does not include a message for minor tinges like blue, brown, or green.
  • Do not buy diamonds from websites or pictures. They can have those lovely 360-degree images, but they will never give you the sparkle of any diamond. You better visit your jeweler and see the diamond yourself.
  • Should I buy a lab-grown or a natural diamond? This is the most asked question. It is all about your priorities. If you have a budget of 5.000-7.000 $ and want a 2ct diamond with an excellent cut, go for a lab-grown one. But you can always select a smaller-carat natural one with the same quality.
  • In the last few years, partners have been going together to buy diamond jewelry. When you have doubts about what your partner wants, ask them. Some people can be ethical enough to choose lab-grown only.
  • Others can see the investment over time and want a natural diamond. Asking your partner doesn’t hurt. It will give you the right idea of what he wants, and you both can be happy.
  • Our last piece of advice will be always to focus on quality. Whether natural or lab-grown, you will have the best results if you focus on quality. After all, we want that fantastic sparkle when choosing any diamond.

Conclusion. The ethical part.

If you have seen the movie Blood Diamonds with Leonardo DiCaprio, you know that there is an ethical problem with buying natural diamonds.

  • The film’s ending, where a conference is held concerning blood diamonds, refers to a historic meeting in Kimberley, South Africa, in 2000. It led to the Kimberley Process Certification Scheme, which sought to certify the origin of rough diamonds to curb the trade in conflict diamonds; the certification scheme has since been mostly abandoned as ineffective.
  • The expression “ethical diamond” has arisen for upright shoppers to recognize precious stones mined without exploiting laborers or the climate.
  • Most natural diamonds are not traceable. From mining to selling, there are so many people involved. Most rough diamonds are sorted and mixed before they are cut and polished. That is why it is impossible to know the certificate of origin. Suppose it is a large mining company or from another source. Some Canadian diamonds are branded, so we see the head, but all the others lost their identity through the diamond channel.
  • With the rise of the Internet in the last few decades, marketing can give you false signals. If you look at the Russian mining companies, they employ thousands of workers while giving back to the community. This can be optimistic, but history has taught us that not everything is accurate. Information in Russia is regulated and controlled, so we do not hear about reports of human rights abuses in the mining industry.

So, what are your options for diamonds?

  • Lab-grown or artificial diamonds. Synthetic diamonds are risk-free for the workers and the environment.
  • Canadian diamonds. Because of the ID number, you can trace the origin. Canada has stringent environmental and fair labor laws.
  • Recycled diamonds. Considering the environment and ethical issues, there is a good alternative. Pre-owned diamonds are often polished and certified again.
  • The Kalahari Dream. De Beers is one of the largest mining companies. That created a venture for mining and selling directly to consumers. It is the ideal solution. For more info, please visit

Frequently Asked Questions

  • What makes diamonds so unusual?

    Diamonds are unusual because they are the hardest known natural substance on Earth. This property is due to the unique crystalline structure of diamonds, made up of carbon atoms tightly bonded in a lattice-like arrangement. This structure gives diamonds exceptional hardness and durability, as well as their high melting point and resistance to scratching, chipping, and other forms of damage. Additionally, diamonds are scarce and are found only in a few parts of the world, which adds to their value and desirability. Furthermore, diamonds are known for their brilliance and fire, the play of light and color that occurs when diamonds are cut and polished into a specific shape. This makes diamonds a popular choice for jewelry and other decorative items.

  • Do diamonds have powers?

    Diamonds do not have any magical or supernatural powers. Diamonds are a type of mineral, precisely a crystalline form of carbon, and they do not possess any special abilities or properties beyond their physical characteristics. Some believe diamonds have specific healing or therapeutic properties, such as improving mental clarity or enhancing emotional well-being. Still, these beliefs are not based on scientific evidence. Additionally, some people may associate diamonds with good luck or other positive qualities, but this is a cultural or personal belief rather than a physical property of the diamond itself.
