Diamond Origin
Lab-Grown vs. Earth-Mined Diamonds
Two origins. One beautiful decision.
Choosing between an earth-mined and lab-grown diamond is a personal choice, and at Crown & Carat, we believe there’s no wrong answer. Different origins, different stories, you choose what matters most to you.
Earth-Mined
Earth-mined diamonds are one of nature’s rarest creations. Formed deep beneath the earth’s surface under immense heat and pressure, most natural diamonds began their journey more than a billion years ago before eventually being brought to the surface and mined. Each is a finite, naturally occurring gemstone shaped by the earth, with its own unique characteristics and history. Every natural diamond we offer is ethically sourced and traceable, so you can feel confident in the diamond you choose.
Lab-Grown
Lab-grown diamonds are real diamonds, but instead of forming beneath the earth over billions of years, they are grown in a controlled laboratory environment over a matter of weeks. Using advanced technology, typically CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature), the conditions that allow a diamond crystal to grow are recreated in a laboratory. The process begins with a tiny diamond seed, onto which carbon atoms gradually form and crystallize, creating a rough diamond that is then cut, polished and graded just like an earth-mined diamond.
The finished result has the same chemical composition, crystal structure and optical properties as an earth-mined diamond. The primary difference is its origin. Because lab-grown diamonds can be produced rather than discovered in a finite natural supply, they are typically available at a significantly lower price point, allowing you to prioritize a larger stone, higher specifications or simply a different budget.
Ultimately, the difference is origin, not whether one is a “real” diamond.
Some clients are drawn to the rarity, billion-year history and natural formation of an earth-mined diamond. Others love the value and flexibility that lab-grown diamonds offer. Your ring should reflect what matters to you, not what someone else tells you to choose.
At Crown & Carat, we work with both earth-mined and lab-grown diamonds and will guide you through each option transparently, without steering you toward either.
Your diamond. Your priorities. Your choice.

The First C
Cut
Cut is what makes a diamond sparkle. It's how well the facets catch and return light, and the most important C for beauty.
Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond's cut as shape (round, heart, oval, marquise, pear), but what diamond cut actually means is how well a diamond's facets interact with light. 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.
Achieving the best cut for a diamond reflects in the stone's final beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyze. To determine the cut grade of the standard round brilliant diamond, the shape that dominates the majority of diamond jewellery, GIA calculates the proportions of those facets that influence the diamond's face-up appearance. These proportions allow GIA to evaluate what the best cut for a diamond is by studying how successfully a diamond interacts with light to create three desirable visual effects.
The Second C
Color
The best diamonds have the least color. Grading runs from D (colorless) to Z (faint yellow), and the difference is often invisible to the naked eye.
Understanding what diamond color means helps in choosing the right diamond. Interestingly, the diamond 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 diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones of established color value.
Many of these diamond 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. Our specialists can help you find the right balance of color and value during your consultation.
The Third C
Clarity
Clarity measures a diamond's tiny natural marks. Most are impossible to see without magnification, so you rarely need to pay for perfect.
To understand diamond clarity, we must first understand how diamonds are created. 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. If you are trying to determine what is the best clarity for a diamond, remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity.
The Fourth C
Carat
Carat is the diamond's weight, not its size, but two stones of equal carat can look and cost very differently depending on the other three Cs.
To put it simply, diamond carat weight measures how much a diamond weighs.
A metric "carat" is defined as 200 milligrams. Each carat is subdivided into 100 'points,' which allows very precise measurements to the hundredth decimal place.
All else being equal, diamond price increases with diamond carat weight because larger diamonds are rarer and more desirable. However, two diamonds of equal carat weight can have very different values (and prices) depending on the three other factors of the diamond 4Cs: Color, Clarity, and Cut.
While now you know what carat means, it's also important to remember that a diamond's value is determined using all of the 4Cs, and not just carat weight.
