Explore the Beauty Nature’s Masterpiece
Mined diamonds are unique gems celebrated for their profound significance in the world of gemstones. Their connection to the Earth makes them natural treasures that resonate with those who value tradition, prestige, and appreciate nature’s beauty. Beyond their shine, mined diamonds carry a rich history, making them a piece to be cherished and passed down through generations. By choosing a mined diamond, you embrace a gem that embodies the wonders of the Earth and serves as a symbol of love and lasting commitment.
Are Mined Diamonds Right for You?Â
-
Aesthetics: Mined diamonds are celebrated for their natural brilliance, fire, and sparkle, making them a popular choice for those who value authenticity. Each diamond is unique, with characteristics like clarity, cut, and colour that contribute to its visual appeal. We make it our mission to help clients carefully select diamonds that enhance their bespoke pieces. We also emphasise the importance of an excellent cut to maximise light performance. Â
-
Cost: Mined diamonds tend to be priced higher due to the labour-intensive process of extraction and certification. The cost is influenced by factors such as carat weight, clarity, and overall quality. We work closely with you to find diamonds that fit both your budget and design preferences, creating a piece that’s not only beautiful but also meaningful.Â
-
Durability: Known for being the hardest natural material, mined diamonds are exceptionally durable and perfect for everyday wear. Their resistance to scratches and damage ensures that your bespoke jewellery, whether it’s an engagement ring, wedding band, or heirloom piece, will remain as stunning as the day you first wear it. This durability makes them an ideal choice for clients looking for long-lasting, timeless designs.Â
-
Ethical Sourcing:Â At Durham Rose, we understand the importance of ethical sourcing. We follow practises to ensure that all our mined diamonds adhere to strict ethical standards, such as the Kimberley Process, which guarantees that the diamonds are sourced responsibly. We are committed to offering diamonds that you can wear with pride, knowing they align with your values.
-
Design Versatility:Â One of the key advantages of mined diamonds is their versatility in design. Whether you envision a classic solitaire engagement ring or a unique, intricate piece, mined diamonds can enhance any design. At Durham Rose, we specialise in working with clients to create bespoke jewellery that reflects your individual style and vision.
Origin
Mined diamonds are formed deep within the Earth’s mantle under intense pressure and heat. They are transported to the surface through volcanic eruptions, creating deposits in igneous rock formations known as Kimberlite, or in alluvial deposits like riverbeds. The earliest diamond trade began in India around the 4th century BC, and by the 1700s, Brazil became a key source. In the 1800s, large diamond reserves were discovered in South Africa, greatly expanding diamond availability beyond royalty and nobility.
Diamonds gained lasting popularity as the symbol of engagement in 1947, following DeBeers’ iconic “Diamonds are Forever” campaign. Ethical concerns in the modern diamond industry have led to initiatives like the Kimberley Process, which ensures that diamonds are conflict-free and responsibly sourced.
Today, diamonds remain highly valued for their beauty, durability, and symbolism, making them a sought-after choice for bespoke engagement rings and other fine jewellery.
Physical Mastery
Proportions:Â
This refers to the dimensions and angles of the diamond’s facets. The ideal proportions allow light to enter the diamond, reflecting off its internal facets and returning to the viewer’s eye. When a diamond is cut to optimal proportions, it achieves a balance that maximises light performance, enhancing its overall brilliance.
Symmetry:
This aspect examines how evenly and accurately the facets are aligned and positioned. A diamond with excellent symmetry will reflect light uniformly, ensuring that the sparkle is consistent across its surface. Even minor deviations in symmetry can impact how light travels through the stone, resulting in noticeable differences in visual appeal.
Polish:
The polish grade assesses the smoothness of the diamond’s surface. A well-polished diamond will have a flawless surface, allowing light to enter and exit without obstruction. Any blemishes or imperfections on the surface can impede light performance, diminishing the stone’s brilliance.
Light Performance
When selecting a diamond for your bespoke ring, understanding how light interacts with the stone is essential. Three key factors determine how well your diamond handles light, ultimately creating its sparkle and beauty:
Brilliance:
Brilliance is the amount of white light that is reflected from the diamond, contributing to its overall brightness. This is measured precisely, with areas of the diamond that reflect light appearing bright and vibrant, while dark areas indicate light loss or leakage. A well-cut diamond will allow it to capture and reflect light effectively, creating a stunning display of brilliance. When you choose a diamond with excellent brilliance, you can be assured that it will shine beautifully, regardless of the lighting conditions.Â
Fire:
One of the most striking attributes of a diamond is its ability to disperse light into a brilliant spectrum of colours, known as fire. Like a rainbow, this sparkling display is best appreciated when the diamond is in motion, as flashes of colour shift with every change in light.
Scintillation:
Scintillation refers to the sparkle created by light reflecting off a moving diamond. It is assessed by observing the bursts of light emitted as the diamond is rotated or moved in the light. A diamond with high scintillation will display a composition of light, creating a sparkling effect that draws attention. This dynamic quality is particularly important for a ring, as it will be viewed from various angles and in different lighting situations.Â
What are the 4C’s?
When embarking on the journey to create a bespoke jewellery piece, it’s important to consider the key factors that influence a diamond’s quality and beauty. Understanding these 4C’s will help you make informed decisions and ensure that your chosen stone perfectly aligns with your vision and preferences. Whether you’re looking for exceptional brilliance, unique colour, or the perfect size, we’re here to guide you through every step of the process, ensuring that your bespoke piece is true reflection of your love story.Â
Cut
Did you know?
The most important “C’ among the 4Cs is the ‘Cut‘
The cut is a fundamental aspect of the 4C’s that significantly influences a diamond’s overall aesthetics and performance. The term “cut” encompasses not only the shape—such as round, princess, or emerald—but also the precision with which the diamond has been faceted and polished. A masterfully cut diamond optimises light return, creating exceptional brilliance, fire, and scintillation. Understanding the nuances of the cut allows you to appreciate how it enhances the diamond’s inherent beauty and value. In the context of bespoke jewellery, a finely cut mined diamond serves as the foundation for your one-of-a-kind piece, making it an essential consideration in your selection process.
ColourÂ
When choosing the right diamond for your bespoke jewellery, it’s essential to understand which diamond colour aligns with your preferences. Do you prefer a warm, pale brown hue or the classic brilliance of a crystal white diamond? Once you’ve identified your preferred colour, the next step is considering your comfort price points. These two factors will help you focus on the ideal colour for your diamond.
Colour plays a pivotal role in a diamond’s character, directly impacting the stone’s overall appearance and beauty. Diamonds range from colourless to light hues, and their grading is based on the absence of colour; the less colour a diamond has, the rarer and more valuable it becomes.
*Kindly note that the illustration below serves to provide an approximation of the diamond’s colour; actual appearances may vary slightly.
The Gemological Institute of America (GIA) has developed an internationally recognised colour grading scale for diamonds, ranging from D (completely colourless) to Z (displaying light yellow or brown tones). Diamonds graded D are exceptionally rare and are highly valued for their icy, pure white appearance. Conversely, diamonds closer to Z exhibit more noticeable colour tints, typically yellow or brown.
Colourless Diamonds (D-F)
Diamonds graded D to F are categorised as colourless, making them the most desirable of all. These diamonds reflect white light with extraordinary brilliance, with no visible colour to distract from their sparkle. As a result, diamonds in this range are among the rarest and most valuable, ideal for those seeking a bright and pristine look in their jewellery.
Near-Colourless Diamonds (G-J)
Diamonds graded G to J fall into the near-colourless category, they have very faint traces of colour, though these are usually imperceptible to the naked eye. In most cases, these diamonds will still appear virtually colourless once set in a piece of jewellery, and they provide a striking balance between quality and cost. For clients looking to maximise value without compromising on beauty, near-colourless diamonds are an excellent option. Their slight warmth often goes unnoticed, especially in settings like white or yellow gold.
Faint to Light Colour (K-Z)
Diamonds in the K to Z range display progressively more noticeable shades of yellow or brown. As the colour becomes more pronounced, it tends to lower the diamond’s value. However, some clients may prefer this warmer hue, particularly when combined with yellow or rose gold settings, where the soft tint can create a harmonious and unique aesthetic. These diamonds can offer a more distinctive, vintage look that appeals to certain tastes and styles.
Clarity
Clarity defines the purity of a diamond by indicating the presence of natural inclusions (internal flaws) or blemishes (surface imperfections) that occur as the diamond forms deep within the earth. While no diamond is completely flawless—except for the rarest stones—clarity helps to define how “clean” a diamond appears to the naked eye and under magnification. These imperfections are often microscopic and do not affect the structural integrity of the diamond. However, the fewer and less visible these flaws, the higher the clarity grade and, consequently, the value of the diamond.
FL & IF – Flawless & Internally Flawless:Â
These Diamonds have no inclusions or blemishes visible under 10x magnification, making them incredibly rare and highly valuable due to their perfect purity. Internally Flawless (IF) diamonds, while also free of internal inclusions, may have slight surface blemishes that are very difficult to detect even under 10x magnification. Though not entirely flawless, IF diamonds still offer exceptional clarity and are almost indistinguishable from FL diamonds to the naked eye, making both grades highly sought after for their rarity and brilliance.
Very, Very Slightly Included (VVS1Â and VVS2):
Inclusions are so minute that they are very difficult to detect even under 10x magnification. These diamonds are nearly flawless and represent excellent quality.
Very Slightly Included (VS1 and VS2):
Inclusions are visible under 10x magnification but are still minor and typically not noticeable to the naked eye. VS diamonds offer a high level of clarity at a more affordable price point than VVS diamonds.
Slightly Included (SI1 and SI2):
Inclusions are noticeable under magnification and, in some cases, may be visible to the naked eye. However, many SI diamonds still offer excellent brilliance, and their inclusions are often hidden by the diamond’s sparkle or by the setting itself.
Included (I1, I2, I3):
Inclusions are visible to the naked eye and may affect the diamond’s brilliance and durability. These diamonds are generally less expensive, but may not offer the best visual appearance for a bespoke piece.
Carat

Please note that while this illustration offers a close representation, the actual size may vary slightly in reality.
What is Diamond Fluorescence?
Diamond fluorescence is essentially how ultraviolet (UV) light affects a diamond. Similar to how whites appear brighter or teeth seem to glow under UV light, diamonds emit visible light when exposed to UV rays. On a Diamond Grading Report, fluorescence indicates the strength of this reaction to UV light, an essential component of daylight.
