Diamonds, symbols of eternal love and luxury, have captivated humanity for centuries. Their unparalleled sparkle and exceptional durability make them prized gems, particularly for crafting exquisite jewelry, such as engagement rings, necklaces, and earrings. But behind this glittering beauty lies a complex and rapidly evolving market, where a diamond's price can fluctuate wildly based on specific criteria like carat, cut, color, and clarity.
Today, consumers face a critical choice: mined diamond or lab-grown diamond? This comparison between mined and lab-grown diamonds is essential for making an informed decision. To decode this shimmering market, it's vital to delve into the criteria that determine a diamond's value, grasp the distinctions between mined and lab-grown diamonds, and compare their prices. This comprehensive guide will provide you with all the necessary tools to navigate the fascinating world of diamonds and answer the ultimate question: "what is the price of a diamond, and more importantly, which diamond should I choose?"
Mined Diamond vs. Lab-Grown Diamond: Origin Makes All the Difference
Before diving into diamond pricing, it's crucial to understand the fundamental difference between mined and lab-grown diamonds. Choosing the right diamond for you hinges on understanding their specific traits and respective advantages.
Picture two ice cubes, each with crystalline purity and captivating beauty. One, formed within a glacier over millennia, radiates the brilliance of eternal snow. The other, created in your home freezer, gleams with human ingenuity. Both consist of frozen water, sharing the same crystalline structure, transparency, and coldness. Their origin alone sets them apart.
The same holds true for diamonds. Is a lab-grown diamond as "real" as a mined diamond? Absolutely! Chemically, physically, and optically, they are identical.
Mined Diamonds: The result of a geological process spanning millions, even billions of years, mined diamonds are extracted from the Earth's depths. Their formation under extreme pressure and temperature imparts a rarity and mystical aura that has fueled their value for centuries. If you seek a rare diamond with a rich history, a mined diamond with a GIA certificate could be the perfect choice. However, diamond mining carries a substantial environmental and social cost, and working conditions in certain mines are often criticized. The ecological footprint of mined diamonds is a significant factor to weigh in your decision.
Lab-Grown Diamonds: Born from human ingenuity and technological breakthroughs, lab-grown diamonds are created in a matter of weeks within sophisticated facilities. By replicating the conditions that form natural diamonds, scientists can produce diamonds with the same chemical makeup, crystalline structure, and brilliance as mined diamonds. They are identical in appearance and physical properties, but their production process is more ethical, sustainable, and transparent. Lab-grown diamonds, also called synthetic or cultured diamonds, offer a responsible alternative to mined diamonds, without sacrificing quality. If you're eyeing an engagement ring with an ethical and affordable diamond, a lab-grown diamond is an excellent option.
In short, diamonds, whether sourced from the Earth's depths or designed by humankind, share the same characteristics. Their value, brilliance, and beauty are indistinguishable; only their origin differs. Mined diamonds result from an age-old natural process, while lab-grown diamonds, created through technology, present an ethical and sustainable choice, without compromising quality.
The 4Cs: Cornerstones of Diamond Evaluation
Whether you're aiming to purchase a mined or lab-grown diamond, its evaluation rests on four fundamental criteria, universally recognized in the gemological world: the 4Cs. These four pillars – Carat, Cut, Color, and Clarity – interact to define a diamond's value and beauty, directly influencing its price. Grasping the significance of each "C" empowers you to choose the diamond that best aligns with your expectations and budget.
Carat (Weight): How Weight Influences a Diamond's Price
Carat measures a diamond's weight. One carat equals 0.2 grams. The higher the carat weight, the rarer and more valuable the diamond becomes. A diamond's price escalates exponentially with its carat weight. This means a 2-carat diamond, all else being equal, won't simply cost twice as much as a 1-carat diamond, but significantly more!
Psychological thresholds also exist at certain carat weights (0.5ct, 1ct, 1.5ct, 2ct, etc.). Buyers often agree to a substantially higher price for a diamond that crosses one of these thresholds, even if the weight difference is minuscule. For example, a 1-carat diamond's price can be markedly higher than a 0.95-carat diamond.

Keep in mind that these prices serve as a guide and can fluctuate based on demand, supply, and market variations. If you're after a specific one-carat diamond, don't hesitate to reach out to a professional diamond dealer for a precise estimate.
Cut: The Make or Break Factor
Cut is arguably the most crucial of the 4Cs. It encompasses a diamond's proportions, symmetry, and polish. An expert cut maximizes a diamond's brilliance, allowing light to penetrate the stone, reflect off its internal facets, and exit through the top, creating the diamond's signature "fire."
Different cut shapes exist, each with unique characteristics and a distinct influence on a diamond's price. The round cut, also known as the brilliant cut, is the most sought-after and typically the priciest, as it optimizes the diamond's brilliance. It's also the most demanding in terms of raw material since achieving the ideal proportions requires sacrificing a larger portion of the rough diamond. If your priority is a diamond with maximum brilliance, the brilliant cut is an excellent choice.
Other cuts, such as princess, emerald, pear, or marquise, offer diverse styles and may come at a more accessible price point.
- The princess cut is a square or rectangular cut exuding intense brilliance and a modern flair.
- The emerald cut is a rectangular cut with truncated corners, emphasizing the diamond's clarity. It's often favored for large diamonds with high clarity.
- The pear cut, also called the teardrop cut, is an asymmetrical cut blending the curves of a round cut with the point of a marquise cut. It frequently graces pendants and earrings.
- The marquise cut is an oval cut tapering to points at both ends, creating the illusion of greater size. It's a popular choice for rings and pendants.
Different diamond cuts: Brilliant cut, emerald cut, marquise cut, pear cut, princess cut.
The quality of the cut has a major impact on the price of a diamond, whether mined or lab-grown. A diamond with an excellent cut can be worth significantly more than a diamond of the same carat weight and color with a mediocre cut.
Color: The Subtle Influence of Hue... and on a Diamond's Price!
A diamond's color is an important factor to consider, both for its aesthetic appearance and its price. While we often imagine the diamond as a perfectly colorless stone, the reality is more nuanced. Indeed, the majority of diamonds used in jewelry have a slight yellow tint.
The GIA color scale and its impact on a diamond's price
To classify diamonds according to their color, the GIA (Gemological Institute of America) has developed a scale ranging from "D" to "Z". Each color grade has a direct impact on the price of the diamond.
Let's take as a reference a 1 carat round brilliant cut diamond, with VS2 clarity and an excellent cut:
- D: Exceptional white +. The ultimate in terms of color, D color diamonds are perfectly colorless. Expect a bonus of +30% to +40% compared to the reference price (grade G).
- E-F: Exceptional white and extra white +. Very close to colorless, with a tiny, almost imperceptible yellow tint. Bonus of +20% to +30% compared to the reference price. If you are looking for an exceptional white diamond, categories E and F are an excellent choice. All our diamonds are certified at least F to guarantee you the whitest diamond, as for the Andrea ring.
- G-H: Extra white and white. A slight subtle yellow tint that does not significantly affect the brilliance. This is often the best value for money. Grade G is our reference price. Grade H offers a reduction of -10% to -15%.
- I-J: Nuanced white. The yellow tint is more noticeable, but remains acceptable, especially if the diamond is mounted on yellow gold. Reduction of -20% to -25% compared to the reference price.
- K-M: Light tint. The yellow color is clearly visible. These diamonds are cheaper, with a reduction of -30% to -40% compared to the reference price.
- N-Z: Notable tint. The yellow color is pronounced. These diamonds are the least expensive, with a reduction of up to -50% compared to the reference price.
"Fancy" colored diamonds: a major influence on price
Beyond white diamonds, there are "fancy" colored diamonds: pink, blue, green, bright yellow, red... These diamonds are extremely rare and sought after. Their price, already high for mined "fancy" colored diamonds, can reach astronomical sums for certain colors and intensities.
Let's take the example of a 1 carat pink diamond, brilliant cut, VS2 clarity:
- Pale pink: + 80% to +150% compared to a white diamond of the same quality.
- Medium pink: +200% to +500%
- Intense pink: +800% to +2000%
- Bright pink: The price can be multiplied by 10, 20, or even 50 compared to a white diamond!
Blue, green, and red diamonds follow a similar trend, with even greater price variations depending on the rarity and intensity of the color. The price of a blue diamond can thus reach incredible heights, making these stones true jewels.
Lab-grown diamonds: an accessible rainbow of colors
Lab-grown diamonds offer a unique opportunity to explore the world of colored diamonds at more affordable prices. Scientists can control the growing conditions to obtain specific colors, thus offering a wide range of choices.

Lab-grown diamonds offer a unique opportunity to explore the world of colored diamonds at more affordable prices. Scientists can control the growing conditions to obtain specific colors, thus offering a wide range of choices.
The clarity of a diamond refers to its degree of purity. In other words, it is a matter of evaluating the presence of inclusions, these small natural imperfections that form during the crystallization of the diamond. Almost all diamonds contain inclusions, but their number, size, and position can vary considerably.

Clarity: Mastering the Clarity Scale to Optimize Your Purchase
The GIA (Gemological Institute of America) has developed a clarity scale to classify diamonds based on their inclusions:
- FL (Flawless): No inclusions visible, even under 10x magnification. This is the highest and rarest level of clarity.
- IF (Internally Flawless): No inclusions visible under 10x magnification, but tiny blemishes may be present on the diamond's surface.
- VVS1-VVS2 (Very, Very Slightly Included): Inclusions are very difficult to see, even for an experienced gemologist using 10x magnification.
- VS1-VS2 (Very Slightly Included): Inclusions are difficult to see under 10x magnification, but may be visible to the naked eye under certain conditions.
- SI1-SI2 (Slightly Included): Inclusions are easily visible under 10x magnification and may be visible to the naked eye for some.
- I1-I3 (Included): Inclusions are visible to the naked eye.
Clarity and diamond price: what impact?
Clarity has a significant impact on a diamond's price. The purer a diamond, the rarer and more precious it is. FL and IF diamonds are the most expensive, while I1-I3 diamonds are the most affordable.
Lab-grown diamonds: often superior clarity
Lab-grown diamonds often have superior clarity to mined diamonds because they are created in a controlled environment where inclusions are minimized. It is not uncommon to find lab-grown diamonds with "VVS" or even "FL" clarity, whereas these clarity levels are much rarer in mined diamonds. If you are looking for a diamond with excellent clarity, lab-grown diamonds are an excellent option.
Price: A Growing Gap Between Mined and Lab-Grown
The main advantage of lab-grown diamonds lies in their price. They are generally less expensive than mined diamonds with comparable characteristics. This price difference is explained by several factors:
- Production costs: Producing lab-grown diamonds is less expensive than mining, which requires significant investment in infrastructure, labor, and energy.
- No intermediaries: The market for lab-grown diamonds is more direct, with fewer intermediaries between the producer and the consumer, which reduces margins and additional costs.
- Market perception: Mined diamonds still benefit from an image of prestige and rarity that influences their price. However, this perception is changing as consumers become aware of the advantages of lab-grown diamonds.
Lab-grown diamonds offer an alternative to mined diamonds, with many advantages that are attracting more and more consumers. If you are concerned about ethics, the environment, and your budget, lab-grown diamonds are an option to seriously consider.
Here are the main advantages of lab-grown diamonds:
- More affordable price: The price of a lab-grown diamond is generally lower than that of a mined diamond with comparable characteristics. This allows you to acquire a larger or higher quality diamond for a given budget. For example, if you are looking for a 2 carat diamond, a lab-grown diamond will allow you to realize your dream without breaking the bank.
- Ethics and sustainability: Lab-grown diamonds are produced under ethical and environmentally friendly conditions. They do not have a negative impact on ecosystems and do not contribute to armed conflicts linked to mining. If you are looking for an ethical and ecological diamond, lab-grown diamonds are the ideal choice.
- Controlled quality: Lab-grown diamonds are created in a controlled environment, which guarantees their quality and purity. It is possible to choose specific characteristics, such as color and clarity, and obtain a perfect diamond, without visible inclusions.
- Traceability: Lab-grown diamonds are often accompanied by a certificate that guarantees their origin and manufacturing process. This gives you the guarantee of an authentic and traceable product.
