Lab-Grown Diamonds: The Modern Choice
At Finite Jewels, we understand that selecting a diamond is about more than just beauty—it's about making an informed, ethical, and sustainable choice. Lab-grown diamonds offer an exceptional alternative to mined diamonds, combining cutting-edge technology with timeless elegance.
What Are Lab-Grown Diamonds?
A lab-grown diamond is created in a controlled environment using advanced technology that replicates the high-pressure, high-temperature conditions under which natural diamonds form deep within the earth. These diamonds are chemically, physically, and optically identical to mined diamonds, meaning they possess the same brilliance, fire, and durability that diamonds are known for.
Despite being indistinguishable from natural diamonds to the naked eye, lab-grown diamonds come at a more affordable price point and are considered a more sustainable and ethical choice. Unlike mined diamonds, which require extensive excavation, lab-grown diamonds have a significantly lower environmental impact, making them a modern, responsible alternative without compromising quality or luxury.
The Key Benefits of Lab-Grown Diamonds
Exceptional Quality & Beauty
Lab-grown diamonds are held to the same high standards as natural diamonds and undergo rigorous grading based on the 4Cs: Cut, Carat, Clarity, and Colour.
More Value for Your Money
Because lab-grown diamonds do not require the costly and labor-intensive process of mining, they are typically 30-40% more affordable than their mined counterparts, allowing you to purchase a larger or higher-quality diamond within your budget.
Sustainable & Ethical
Mined diamonds often involve extensive land disruption and carbon emissions, whereas lab-grown diamonds require far fewer natural resources, can be produced using renewable energy and require significantly less water than mining. Additionally, they are 100% conflict-free, offering peace of mind when making your purchase.
Identical Composition
Both lab-grown and natural diamonds are made of pure carbon arranged in a crystal lattice structure, ensuring the same hardness (10 on the Mohs scale) and light performance.
Certified & Graded
Just like natural diamonds, lab-grown diamonds are independently certified IGI (International Gemological Institute), ensuring transparency and authenticity in every stone.
At Finite Jewels, we take pride in offering premium-quality lab-grown diamonds that provide exceptional brilliance, ethical sourcing, and remarkable value.
Natural Diamonds: The Timeless Choice
What Are Natural Diamonds?
A natural diamond is formed deep within the Earth's mantle over billions of years under intense heat and pressure. Each stone is a rare geological miracle, brought to the surface through natural processes and shaped into the dazzling gems admired around the world.
No two natural diamonds are ever exactly alike, giving each one its own unique character and charm. Their rarity and natural origin make them symbols of prestige and timelessness, often cherished as heirlooms passed down through generations. Beyond their unmatched brilliance and durability, natural diamonds hold enduring value, making them both a treasure to wear today and a legacy to preserve for the future.
The Key Benefits of Natural Diamonds
Timeless Rarity & Natural Beauty
Formed deep within the Earth over billions of years, each natural diamond is a rare geological wonder. Their brilliance, durability, and uniqueness make them timeless symbols of love and luxury.
Enduring Value
Natural diamonds are widely recognised for their ability to hold long-term value. Their rarity and global demand make them a meaningful investment as well as a cherished piece of jewellery.
Symbol of Legacy
More than a jewel, a natural diamond is a legacy. Their unique origin and timeless appeal make them ideal heirlooms, passed down through generations as symbols of love, achievement, and commitment.
Exclusivity & Prestige
Because no two natural diamonds are exactly alike, owning one brings a sense of exclusivity and prestige. Each stone carries an individuality that reflects both nature's artistry and the wearer's personal story.
Certified & Graded
Natural diamonds undergo rigorous grading by the Gemological Institute of America (GIA), the world's most respected authority in diamond certification. This ensures authenticity, quality, and complete transparency in every purchase.
At Finite Jewels, we offer a curated selection of natural diamonds that embody timeless beauty, rarity, and enduring value.

Engagement Ring Styles & Settings
At Finite Jewels, we know that choosing an engagement ring is an exciting but sometimes overwhelming experience. Understanding the fundamentals of engagement ring styles and settings will empower you to make a confident choice.
Ring Structure at a Glance
Understanding Ring Styles & Settings
Ring Style
Defines the overall aesthetic and structure of the ring. This includes solitaires, halos, three-stone rings, and more.
Ring Setting
Refers to how the diamond is secured in the ring, such as prong, bezel, or pavé settings.
Engagement Ring Styles
The style defines the overall design and aesthetic of your ring. From classic solitaires to intricate halos, each style creates a unique look and presence.
Solitaire Rings
The Timeless Classic
The solitaire engagement ring is perhaps the most iconic and enduring style, celebrated for its understated elegance and ability to showcase a single, brilliant diamond. The term solitaire refers to a single gemstone, unaccompanied by side stones or embellishments, allowing its beauty to take centre stage.
This design has been a favourite for centuries, symbolising pure, undivided love. Despite its minimalist nature, solitaire rings offer a wealth of design variations, from the setting style to the band shape. The diamond can be secured in a classic prong setting, elevated in a cathedral setting, or encased in a sleek bezel setting for a modern touch. The simplicity of the solitaire ring allows for customisation, making it an ideal choice for those who value both tradition and personal expression.
Halo Engagement Rings
A Radiant Statement
The halo engagement ring emerged in the Victorian era, where jewellery design was influenced by opulence and grandeur. This style features a central diamond surrounded by a circle of smaller diamonds, creating an effect that enhances size and brilliance.
The additional stones reflect light back into the centre diamond, intensifying its sparkle and giving the illusion of a larger stone. Halo settings have evolved over time, incorporating modern and vintage-inspired variations. Some feature double halos for even greater radiance, while others adopt hidden halos, where smaller diamonds are set beneath the centre stone, visible only from the side.
Hidden Halo Engagement Rings
Subtle Brilliance
A hidden halo is a contemporary evolution of the traditional halo ring, offering an unexpected element of brilliance. Unlike a standard halo, where the smaller diamonds encircle the centre stone from a top-down view, a hidden halo is placed beneath the prongs of the setting.
This detail is only visible from the side, adding an extra layer of light reflection and intricacy. This style is ideal for those who appreciate subtle luxury, as it enhances the centre stone's brilliance while maintaining a clean, minimalist aesthetic. Many solitaire rings can be adapted to include a hidden halo, making it a versatile option for those seeking a refined yet radiant ring.
Three-Stone Engagement Rings
Past, Present & Future
The three-stone engagement ring is a deeply symbolic design featuring a central diamond flanked by two complementary stones, representing the past, present, and future of your love story. This style gained popularity in the early 20th century and remains a cherished choice for couples seeking meaningful symbolism.
The beauty of three-stone rings lies in their versatility and personal significance. The centre stone typically represents the present moment, while the side stones honour your shared history and future dreams together. These rings can feature matching stones for symmetrical elegance, or incorporate different cuts and sizes for a more contemporary interpretation. The setting can vary from classic prongs to modern channels, each offering its own aesthetic appeal.
Diamond-Set Engagement Rings
Elegant & Enhanced Sparkle
A diamond-set engagement ring introduces additional diamonds along the band, complementing the centre stone while elevating the overall brilliance of the ring. Unlike a halo setting, where smaller diamonds surround the centre stone, diamond-set bands feature accent stones along the shank.
This style has been favoured for centuries, particularly in Edwardian and Art Deco jewellery, where intricate detailing and shimmering surfaces were highly sought after. The setting style of the accent diamonds plays a significant role in the ring's final appearance—whether it's the pavé setting, where tiny diamonds appear as though they are seamlessly "paved" into the band, or the channel setting, which offers a modern, streamlined look.
Engagement Ring Settings
The setting is how your diamond is secured and presented in the ring. Each setting style affects both the appearance and security of your stone.
Prong Setting
Classic & Brilliant
The prong setting is the most well-known and widely used method for securing a diamond in an engagement ring. This design features small metal claws (or prongs) that grip the diamond, lifting it above the band to allow maximum light entry.
By exposing more of the stone's surface, prong settings enhance brilliance, fire, and overall sparkle. Prong settings can be tailored to different aesthetics—claw prongs add an elongated, elegant effect, while button prongs offer a more rounded, delicate look. The number of prongs also affects the ring's style and security; a four-prong setting provides a minimalist, floating effect, whereas a six-prong setting offers added security while slightly altering the visual shape of the diamond.
Cathedral Setting
Elevated & Elegant
Inspired by the grandeur of cathedral architecture, this setting is defined by graceful arches that rise from the band to cradle the centre stone. By lifting the diamond, the cathedral setting creates height and prominence, allowing more light to pass through the diamond for enhanced brilliance.
This design has been cherished for centuries, particularly in traditional European engagement rings, where height and elegance were seen as markers of refined craftsmanship. While cathedral settings inherently feature a high-set diamond, they can be adjusted for varying degrees of prominence, offering both subtle and dramatic silhouettes. From a side profile, the curved arches add an element of sophistication.
Bezel & Demi-Bezel Setting
Sleek & Secure
A bezel setting is one of the oldest and most secure methods for setting a diamond, where a thin metal rim encircles the stone's edges, holding it firmly in place. Unlike a prong setting, which leaves the sides of the diamond exposed, a bezel setting completely or partially surrounds the stone.
This setting offers maximum protection against knocks and daily wear. Historically, bezel settings were popular in ancient jewellery, prized for their durability and seamless appearance. Today, they have been reimagined into sleek, modern designs, often paired with a wave shank or minimalist band. A demi-bezel setting is a variation where the metal only partially encircles the stone, allowing more light entry while maintaining a high level of security.
Pavé Setting
A Continuous Sparkle
The pavé setting derives its name from the French word for "paved", as it features small diamonds set closely together, covering the band in a brilliant, shimmering surface. This technique, refined during the Art Deco period, creates a luxurious, diamond-encrusted look.
The pavé setting allows the metal to remain subtle and minimal while maximizing sparkle. Pavé-set bands are designed to complement the centre stone without overpowering it, making them an ideal choice for those who seek sophistication and brilliance in equal measure. The technique requires exceptional craftsmanship to ensure each small diamond is perfectly aligned and secure.
Channel Setting
Smooth & Modern
A channel setting secures diamonds within a metal groove along the band, creating a seamless row of stones with a sleek, structured appearance. Unlike pavé settings, which use tiny prongs to hold each stone, the channel setting sandwiches the diamonds between two solid metal edges.
This creates a flush, protected design that's perfect for those who prefer clean lines and understated luxury. The channel setting offers excellent protection for the diamonds while maintaining a contemporary aesthetic. This setting is particularly popular for wedding bands and anniversary rings, where durability and elegance are equally important.
Tension Setting
Modern & Striking
The tension setting is one of the most contemporary and innovative engagement ring designs. In this style, the diamond is held in place solely by the pressure of the band, creating the illusion that the stone is suspended or "floating" in mid-air. The result is a striking, minimalist look that maximises light exposure for exceptional brilliance.
Originally developed in the late 20th century, tension settings require expert craftsmanship to ensure both security and precision. While the diamond appears to defy gravity, the band is carefully engineered to grip the stone firmly in place. This setting is ideal for those who admire bold, modern aesthetics and enjoy jewellery that blends engineering with elegance.
Bar Setting
Bold & Structured
A bar setting secures each diamond between two vertical metal bars, leaving the sides of the stones exposed to light while keeping them firmly anchored. This design creates a series of stones set in parallel, offering both structure and brilliance.
Popular in both engagement rings and wedding bands, bar settings are admired for their durability and balanced appearance. The visible sides of the diamonds allow for greater sparkle compared to channel settings, while the metal bars provide a contemporary, geometric style. This setting is perfect for those who appreciate clean lines and a bold, modern presence.
Cluster Setting
Dramatic & Creative
The cluster setting arranges multiple smaller diamonds closely together to form the illusion of a larger centrepiece or to create unique, decorative shapes. This style allows for imaginative arrangements, from floral-inspired designs to starbursts and geometric patterns.
Cluster settings became especially popular in the Victorian era, where ornate and elaborate designs were favoured. Today, they are prized for their ability to achieve maximum impact and sparkle at a more accessible price point, since smaller diamonds can create a dazzling presence. For those who enjoy creativity and statement-making jewellery, a cluster setting is a bold and radiant choice.
Tiffany Setting
Iconic & Elevated
The Tiffany setting, introduced by Tiffany & Co. in 1886, is perhaps the most famous engagement ring design in history. It features six prongs that lift the diamond high above the band, allowing light to pass through the stone from every angle. This design redefined how diamonds were showcased, setting the standard for brilliance and elegance.
Beyond its technical innovation, the Tiffany setting carries cultural significance as a symbol of classic romance and luxury. While many jewellers offer variations of the six-prong design, the original Tiffany setting remains a timeless icon. For those who want a piece of jewellery steeped in tradition and prestige, this setting is the ultimate classic.

BOOK CONSULTATIONJewellery Care Guide
Your bespoke jewellery is made to be worn and enjoyed — but with a little care, you can help it stay looking its best for years to come.
General Care Tips
Avoid exposure to chemicals
Keep away from cleaning products, perfumes, hair sprays, or chlorine — these can dull both metal and stones over time.
Remove during activities
Take off your jewellery when exercising, swimming, cooking, or cleaning — not only to protect the piece, but also to reduce the chance of accidental knocks or loss.
Store it properly
Keep in a soft-lined box or pouch when not in use, ideally separate from other pieces to prevent scratches.
How to Clean Your Jewellery at Home
You'll need:
- Mild dish soap
- Warm water
- A soft toothbrush or jewellery cleaning brush
- A soft, lint-free cloth
- A small bowl or container
Avoid using:
- Household cleaners, bleach or acetone
- Ultrasonic cleaners, unless specifically recommended
- Tissues or paper towels, which can cause micro-scratches
Step-by-step cleaning guide:
Prepare a cleaning solution
Fill a bowl with warm water and add a small drop of mild dish soap. Avoid anything with harsh chemicals or abrasives.
Soak the ring
Place your ring in the solution and leave it to soak for around 20–30 minutes. This will loosen any dirt, oil, or residue.
Gently brush
Using a soft toothbrush, carefully clean around the stone and setting — especially underneath the diamond and around the prongs, where buildup often collects.
Rinse thoroughly
Run the ring under warm water to wash away soap and loosened debris.
Dry and polish
Pat dry with a clean, lint-free cloth. If you have a jewellery polishing cloth, you can gently buff the band to restore shine (avoid polishing gemstones directly).
Want a Deeper Clean?
If your jewellery needs a deeper clean or professional check-up, we recommend visiting a reputable local jeweller who offers cleaning services. Most will offer this as a one-off or annual service, especially for engagement rings and pieces worn daily.
