What Exactly Is a Lab-Grown Diamond?

A lab-grown diamond is a real diamond. It shares the same chemical composition, crystal structure, and optical properties as a mined/natural diamond. Under professional gemologist testing, it is identified as a diamond.

The only difference is origin: mined diamonds are formed beneath the Earth over billions of years; the other is grown by science in a controlled environment. Both are diamonds.

Instead of developing deep within the earth over billions of years, lab-grown diamonds are created using technology in highly controlled environments to replicate natural diamond-growing conditions.

Same structure, same brilliance, same durability.

Lab-Grown vs Natural Diamonds: Understanding the Difference

 

Origin, Not Appearance

Mined (Natural) diamonds form over billions of years beneath the earth’s surface. Lab-grown diamonds are created in controlled environments that mirror those conditions. Visually, structurally, and chemically, they are indistinguishable without specialized equipment.

Quality Control

Because lab-grown diamonds are created under precise conditions, they offer exceptional consistency in cut, clarity, and brilliance—qualities highly valued in fine jewellery.

Modern Value Perspective

For many modern buyers, lab-grown diamonds allow greater freedom: investing in design, craftsmanship, and personal priorities without compromising social elegance or aesthetic standards.

So, yes. Lab grown diamonds are real diamonds.

As real as it's meaning, values and how something makes you feel, it's beyond rarity. It's choosing intentionally. It's identity.

Choose Based on the Values ​​You Hold

Ultimately, diamonds aren't just about sparkle, but about the story you want to tell. Natural diamonds offer a classic narrative of natural rarity and a long history, while lab-grown diamonds represent a more conscious, innovative, and relevant modern luxury.

Sol et Terre presents lab-grown diamond jewelry designed with a thoughtful approach to luxury, combining elegant design and craftsmanship, highest quality diamonds, and a commitment to transparency.

Each Diamond Collection is created not just to be worn today, but to accompany life's journey with values ​​that feel personal and responsible.

The 4Cs: What Truly Determines Diamond Beauty

Cut

Cut defines brilliance. A well-cut diamond reflects light with precision, creating sparkle that feels alive rather than excessive.

Color

From icy whites to warmer tones, color selection is a matter of taste and harmony with metal choice.

Clarity

Clarity speaks to purity. At Sol et Terre, inclusions are evaluated not only by grade, but by how they appear to the naked eye.

Carat

Carat is presence—not just size. Proportion and balance matter more than numbers alone.

At Sol et Terre, our role is not to overwhelm, but to guide you—so each diamond feels right, not just impressive.

 

Do Lab-Grown Diamonds Sparkle the Same?

It is Science meets beauty.

Brilliance is determined by cut; not by origin. A well-cut lab-grown diamond displays the same fire, scintillation, and light performance as a natural diamond. They have the same brilliance, hardness and durability as mined diamond.

In fact, the controlled growing process often allows for higher clarity and precision, enhancing the diamond’s ability to reflect light beautifully.

For an elegant look that emphasizes classic simplicity,  Sol et Terre's Round Diamond Stud Earrings  are the ideal choice. Their round cut reflects light in a balanced way, creating a clean shine that feels both serene and timeless.

Meanwhile, for those seeking a soft, modern take,  the Round and Pear Diamond Pendant  offers the harmony of two contrasting yet harmonious diamond cuts. Its minimalist, effortless, and personal design embodies the balance between beauty and mindfulness.

 

Using advanced HPHT or CVD technology, scientists replicate the natural diamond‑growing conditions with precision.

This allows for exceptional control over clarity, cut, and quality — resulting in diamonds that often surpass traditional expectations of perfection.

Diamond cut has the greatest impact on brilliance because it determines how light reflects within the stone, making it more important than clarity or color.

Are Lab-Grown Diamonds Certified?

 

Yes. Reputable lab-grown diamonds like Sol et Terre are graded and certified by internationally recognized laboratories using the same 4C standards—Cut, Color, Clarity, and Carat Weight; applied to natural diamonds.

Certification matters because it provides transparency and protects the buyer. It ensures that what you see, what you are told, and what you receive are aligned.

At Sol et Terre, certification is not optional. It is fundamental.

Sol et Terre presents lab-grown diamond jewelleries designed with a thoughtful approach to luxury, combining elegant design and craftsmanship, highest quality diamonds, and a commitment to transparency through certification.

What Actually Makes a Diamond Sparkle

Diamond Cut vs Brilliance

What Is Diamond Brilliance?

Brilliance refers to the amount of white light reflected back to the eye. A well-cut diamond maximizes light return, while a poorly cut stone—even with high clarity—can appear dull.

Why Diamond Cut Matters More Than Color or Clarity

Brilliance isn’t accidental—it’s engineered. Understanding cut ensures your diamond shines for a lifetime. (1) Diamond Cut have the ability to control light entry and exit (2) Poor colour proportions may cause light leakage (3) Excellent cutting can enhance perceived size and even brightness. This is why a smaller, well-cut diamond can outshine a larger but poorly cut stone.

How Different Diamond Cuts Perform

In a Round Cut Brilliant : Maximum sparkle appears due to ideal symmetry. While in an Emerald Cut Diamond : The Cutting Lower it's sparkle, but then make the higher clarity an emphasis of it's beauty. In a Pear & Marquise Diamond Cut : Dynamic brilliance happens with directional light play

Which Diamond Cut Truly Suits You?

Choosing between Diamond Cuts, less about trends and more about what resonates your own personality, lifestyle, and values. In the example above, Round Cut Diamonds are ideal for those who appreciate tradition, warmth, and versatility. Meanwhile Emerald Cut Diamonds best suited for those who value clarity, structure, and timeless restraint.

Which One Lasts Longer, Emotionally?

The right choice is the one that feels natural to you, not impressive.
