Reasons why diamond are the best complements to engagement rings and how to choose them

For many women, the engagement ring holds a special place their heart as it represents the promise and commitment that their husband vow to uphold when they proposed. When you think about engagement rings, what is the first thing that pops into your head? Diamonds, isn’t it? The beautiful, shining gem that is so coveted by women around the world. Like the saying goes, “Diamonds are a girl’s best friend”. So why are diamonds most often used in engagement rings?

In this article, we’ll show you why diamonds are good for engagement rings and the key points when choosing a diamond engagement ring.

Why diamonds are the best gems for engagement rings.

Origins of Diamonds

Diamonds are reportedly found in India as early as 500 BC. Diamonds collected from rivers were not considered to be valuable as gems at the time, as they were not shining, and the cutting and polishing techniques were undeveloped. However, attention was focused on the feature that it is significantly harder than other stones.

Due to this distinctive feature, the method of polishing diamonds had not been established for a long time. However, in Belgium in the 15th century, the method of “polishing diamond with diamond powder” was discovered, and the diamond that gained brilliance from it became highly coveted in the world as a gem that is both rare and beautiful.

The meaning of diamond

Diamonds also mean “everlasting love” because their outstanding hardness keeps them shining forever without being damaged. The diamond, in its rarity and beauty, is a symbol of purity and innocence, of love and fidelity, and embraces strength of character, ethics, and faithfulness to oneself and others. It’s truly a symbol of marriage, and it’s no wonder it’s the best complement for engagement rings.

People who choose gems other than diamonds

While many choose diamonds for their engagement rings, others choose non-diamond gems. Everybody wants a unique engagement ring that is different from others and customized them. For gems other than diamonds, rubies and sapphires are the preferred choices. Engagement rings require rarity, hardness and brilliance, and rubies and sapphires meet all three. In addition, birthstone is sometimes used as the centerpiece of the engagement ring for a more personal feel.

Basic diamond knowledge you should know

Throughout history, diamonds have fascinated people from all over the world. Here, we will explain the evaluation criteria of diamond and the shape that is the basis of the design in layman terms.

The 4 Evaluation Criteria of Diamonds

Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.


Diamond carat weight is the measurement of how much a diamond weigh. A metric “carat” is defined as 200 milligrams.

Each carat can be subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a ‘twenty-five pointer.’ Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as ‘one point oh eight carats.’

All else being equal, diamond price increases with carat weight, because larger diamonds are rarer and more desirable. But two diamonds of equal carat weight can have very different values (and prices) depending on three other factors within the 4Cs: Clarity, Color, and Cut. It’s important to remember that a diamond’s value is determined using all of the 4Cs, not just carat weight.


The color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established color value.

GIA’s D-to-Z color-grading scale is the industry’s most widely accepted grading system. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z. Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.


Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’ Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher its value.

The GIA Clarity Scale has 6 categories, some of which are divided for a total of 11 specific grades.

Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader. To the naked eye, a VS1 and an SI2 diamond may look exactly the same, but these diamonds are quite different in terms of overall quality. This is why expert and accurate assessment of clarity is extremely important. Diamonds that do not show inclusions and blemishes at 10x magnification are given the rating “Flawless” (FL), which means they have the least impurities and the highest clarity.


Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond’s cut as shape (round, emerald, pear), but a diamond’s cut grade is really about how well a diamond’s facets interact with light. The biggest factor that determines the brilliance of a diamond is the cut. GIA’s diamond cut grades are only evaluated for 57-sided or 58-sided shapes called “round brilliant cuts” that are the most common type of engagement ring.

Proportion is an evaluation of the shape that determines the brilliance of a diamond, and whether or not it has a shape that reflects light is evaluated using data that measures dimensions and angles. In addition to this, polishing that evaluates the surface condition and the symmetry evaluation of the diamonds are combined to make a comprehensive judgment. From the highest to the lowest, there are five grades: “Excellent,” “Very Good,” “Good,” “Fair,” and “Poor.”

Precise artistry and workmanship are required to fashion a stone, so its proportions, symmetry, and polish deliver the magnificent return of light only possible in a diamond. The quality of cut is crucial to the diamond’s final beauty and value. And of all the 4Cs, it is the most complex and technically difficult to analyze.

Variety of diamond shapes

Diamonds come in many shapes. Among them, the round brilliant cut that is the only GIA cut grade evaluation is popular as a shape that makes diamonds shine beautifully.

In addition, “Princess” that features a square with sharp corners, “Emerald” that gives a classical impression by cutting rectangular corners, “Asher” that makes the diamond almost square, and “Oval” that is oval-shaped and gentle. There are many shapes, such as “Marquis” that mixes softness and sharpness by sharpening both ends of the ellipse, and “heart shape” that is cut into a heart shape that symbolizes love.

Key points when choosing a diamond engagement ring

Although 4C’s diamond rating may not be noticeable if you are not an expert, the following points should be helpful when choosing a diamond as an engagement ring:

We recommend choosing diamonds for engagement rings of at least 0.3 carats. Below that, some people may feel too “small”. 0.3 carat is neither too big nor too small, it looks good and is popular because the price is average as an engagement ring.

It is recommended to choose colors rated D to F (F or higher). In the color grading evaluation, the highest grades D to F are colorless. The difference between D and F is slight, and it is usually indistinguishable. If you want to be particular about quality, choose D while considering other conditions, such as F if you want to balance price and quality.

Clarity, which is difficult to judge unless you are an expert, will not cause any problem if you select a grade higher than “VS”. VS is a grade that “inclusion can be confirmed at a magnification of 10 times, but it can be characterized as minute”, and the level of transparency is high enough to make it difficult to detect blemishes. With VS or higher, inclusions and blemishes are almost invisible to the naked eye.

When choosing the diamond for your engagement ring, our recommendation is the ‘Excellent’ cut. Out of the five grades of cuts, Excellent is the highest. The difference between Excellent and the next best which is Very Good may be hard to see through showcases. The cut’s evaluation is based on how well it receives and reflects light. Excellent has the ideal shape for efficiently and accurately reflecting and emitting the light incident from the top and brings out the brilliance of diamond.

Brand, design, price, quality and what to focus on

There are many types of engagement rings, so unless you decide which axis to choose, it will be difficult to decide, and it will take time to purchase. There are many elements to a diamond engagement ring, including brand, design, price, and 4C rated quality. It is necessary to decide the points that you want to focus on and narrow down the options. If you want to think about the wedding ring together, such as matching the engagement ring and the wedding ring under the same brand, it is better to check the preference of men.

The value of diamonds
The diamond, called the “everlasting shine”, can change significantly in value with very few differences. That’s why we also want to carefully select the engagement ring with diamonds.

The key to choosing one engagement ring from the many is to clarify the criteria and points to choose from. Consider the design, brand, jeweler’s evaluation, budget, etc. and write down the “points you want to focus on”. If you prioritize on that, you will have a basis for ring selection, and you will be able to select without much hesitation.

We hope that you have gain much knowledge from this article and choose your engagement ring with ease.
