OUR COLLECTIONS
Choosing an engagement ring is one of the most important jewellery decisions you’ll ever make. It’s not just about appearance — it’s about quality, proportion, craftsmanship, and longevity.
For over 26 years, McGuire Diamonds has been Ireland’s trusted name for bespoke diamond engagement rings, known for precision, skill, and value.
The Irish jewellery market has evolved rapidly in recent years. Buyers today are informed, value-driven, and focused on ethical luxury. McGuire Diamonds has led that shift through its expertise in lab-grown diamonds — stones identical in brilliance and structure to mined diamonds but with full traceability and exceptional value.
Clients across Ireland are now choosing lab-grown diamonds because they allow for superior quality and size at a more accessible price point. This transparency and efficiency align with what modern buyers want: true quality and honest value.
The average spend on an engagement ring in Ireland is around €4,000, but the right budget depends entirely on the client. Our focus is always on maximising quality within your chosen price range rather than following any “rule of thumb.”
Because lab-grown diamonds typically cost 80-90% less than mined equivalents, clients often find they can purchase a larger or higher-grade diamond without increasing their budget. Every McGuire Diamonds ring, regardless of price, is built to the same exacting standard of craftsmanship and finish.
The choice of metal affects not only the look of your ring but also its performance and durability.
Yellow gold has seen a strong resurgence in Ireland for its warm, classic tone. White gold offers a clean, modern appearance that enhances a diamond’s brilliance, while platinum remains the most durable and prestigious option — naturally white and resistant to wear. Rose gold provides a softer, distinctive hue that appeals to clients seeking individuality.
Every diamond setting is engineered for structural integrity and precision. We ensure perfect alignment, comfort, and longevity in every design.
McGuire Diamonds is recognised as one of Ireland’s leading authorities in lab-grown diamond engagement rings. Lab-grown diamonds are identical to mined stones in every measurable way — chemical composition, hardness, brilliance, and fire. The only difference lies in origin.
Created using advanced technology that replicates the earth’s natural diamond-forming process, lab-grown diamonds offer:
Complete traceability and ethical sourcing.
Exceptional value compared to mined equivalents.
The ability to choose a larger or higher-quality diamond within budget.
Each diamond supplied by McGuire Diamonds is independently certified and hand-selected for cut precision and visual performance.
When selecting an engagement ring, the design style defines both its aesthetic and its craftsmanship. McGuire Diamonds specialises in three core styles: solitaire, three-stone, and halo — each with distinct characteristics and technical requirements.
The solitaire is the most classic and refined of all styles. It features a single diamond secured by a minimal setting designed to maximise light return. The focus is entirely on the quality of the stone and the precision of the cut. A well-executed solitaire requires expert proportion and balance — it’s the true test of a jeweller’s skill.
A three-stone ring features a central diamond flanked by two slightly smaller side stones. The design symbolises balance and progression, but its real value lies in symmetry and proportion. The side stones must complement — not compete with — the centre diamond. At McGuire Diamonds, each three-stone ring is individually planned for scale and harmony, ensuring the result is elegant, not crowded.
A halo ring surrounds the central diamond with a precise circle of smaller stones. The effect increases brilliance and creates the impression of a larger centre diamond. A well-made halo demands meticulous stone setting to maintain symmetry and avoid excess metal. McGuire Diamonds crafts halo settings that are refined, durable, and technically exact — avoiding the bulky, mass-produced appearance often seen elsewhere.
Each style can be further customised by diamond shape, setting type, and band profile, allowing every client to achieve a ring that is both technically perfect and individually suited.
A diamond’s beauty is defined by the Four Cs — cut, colour, clarity, and carat weight. McGuire Diamonds educates each client on these factors to ensure every decision is informed and precise.
Cut: The most critical factor in brilliance. We select only excellent and ideal cuts for maximum light performance.
Colour: Graded from D (colourless) downwards; most McGuire Diamonds stones fall between D–F for crisp, white brilliance.
Clarity: Refers to internal inclusions. Our diamonds are chosen for eye-clean clarity and symmetry.
Carat: Indicates weight, not size. Lab-grown options allow clients to choose larger carat weights without compromising quality.
Shape is equally personal. Round, oval, cushion and emerald cuts remain the most popular in Ireland, each offering a distinct aesthetic. Our specialists help clients identify the shape and proportions that best complement their hand — one of the most important aspects of getting the design right.
McGuire Diamonds is widely regarded for its bespoke engagement rings in Ireland. Each design begins with a private consultation, either in our showroom or online, where clients meet directly with a diamond expert to discuss their preferences, design ideas, and budget.
With decades of experience, McGuire Diamonds excels at guiding clients through every decision — from diamond selection to setting style and proportion. Precision in design ensures that each ring looks balanced, feels comfortable, and reflects the client’s personal taste. This attention to individual fit and proportion is one of the main reasons many of our new clients come through referrals from those already wearing one of our rings.
Once a design is approved, production begins in our workshop. Bespoke engagement rings typically take four to five weeks to complete from order. During this time, our craftsmen oversee every stage: CAD design, metal casting, diamond setting, polishing, and final quality inspection. The result is a ring built to exact standards of accuracy and strength.
McGuire Diamonds serves clients both online and in person. Our showroom appointments allow clients to view and compare diamonds directly, while online consultations provide the same expert guidance and detailed visual references.
Each ring — regardless of how it is purchased — comes with full certification, secure nationwide delivery, and lifetime aftercare. Quality control, diamond selection, and finishing all take place under one roof to maintain complete consistency.
An engagement ring is a precision piece of craftsmanship, and regular maintenance preserves its appearance and structural integrity. McGuire Diamonds offers professional cleaning, inspection, and resizing to ensure every ring remains in perfect condition.
All our rings are supplied with independent diamond certification and documentation for full transparency. This level of care reflects our long-term philosophy. A ring should perform perfectly for decades, not just look good at the point of sale.
For more than 26 years, McGuire Diamonds has earned its reputation for excellence through consistency, skill, and client trust. Ireland’s leading producer of lab-grown diamond engagement rings, combining cutting-edge technology with traditional craftsmanship.
Our business has grown primarily through referrals from satisfied clients — a reflection of the quality, precision, and value built into every ring we create. No shortcuts, no inflated prices, and no gimmicks — just expert advice, honest workmanship, and exceptional results.
