Engagement Ring: How to Choose the Perfect One?

An engagement ring today tells a singular story. It is no longer a standard formula dictated by the advertising campaigns of the last century. It is a meaningful choice, a one-of-a-kind piece that carries your story, your tastes, your vision of commitment. This guide helps you choose yours with confidence: stone, metal, setting, budget, size and personalisation. Objective criteria for a deeply personal decision.

The stone is the heart of the ring. The choice is guided by emotion as much as by durability. Two families dominate: the classic Diamond and coloured stones, which have seen strong growth over the past ten years. Five stones form the core of our engagement rings: the Diamond (the timeless choice), the Sapphire (faithfulness), the Ruby (passion), the Emerald (hope) and the Black Diamond (modernity).

The Diamond remains the historic benchmark. The 4Cs (cut, color, clarity, carat) summarise the evaluation criteria: the round brilliant cut captures and reflects light like no other shape. From 0.8 carat, our internal threshold for a significant purchase, a gemological certificate (GIA, HRD, IGI) guarantees authenticity and documents the exact characteristics of your stone. It is an investment to be passed down through generations.

The Sapphire has a hardness of 9 on the Mohs scale, second only to the Diamond: it endures across decades without losing its brilliance. Kate Middleton wore one on her finger, and the world followed. Deep blue, powder pink or milky white, it extends far beyond the classic blue.

The Ruby carries the symbolism of passion: a classic red in 18ct gold, never saccharine, never flat. The Emerald calls for a little more care (its natural inclusions, known as the "garden," are part of its identity), yet its deep green, expressed through our signature gradient Canopée Emerald (from dark tsavorite to light tsavorite by way of emerald), is truly unlike anything else.

The Black Diamond, opaque and geometric, embodies modernity. Each stone has its own dedicated guide for those who wish to explore further:

The carat measures the weight of the stone, not its visual size. One carat is equal to 0.20 grams. A one-carat stone in a round brilliant cut is not the same size as a one-carat stone in an emerald cut (rectangular): the distribution of weight within the stone changes the visible surface area. Never compare two stones by carat weight alone without considering their shape.

Of course, carat weight matters: the higher it is, the higher the price. But at Mayuri, we recommend that those choosing their engagement ring first ask themselves the question of the desired effect: do you prefer a more understated ring, suited to everyday wear, or do you dream of a more striking piece with a wow factor? These are deeply personal choices, and there is no wrong answer.

Do not be misled by myths: there is no universal rule such as "a minimum of 0.5 carats" or "1 carat required." The right weight is the one that suits you visually, financially, and symbolically. A perfectly cut 0.3-carat stone on a slender hand can be spectacular. Conversely, an oversized stone poorly proportioned on an ill-fitting setting misses the mark entirely.

The metal carries the stone and touches your skin every day. This choice determines the durability, hypoallergenic properties, and aesthetic of the ring.

18ct gold is at the heart of our offering. 75% pure gold (also referred to as 750 parts per thousand), alloyed with other metals for strength. Our 18ct yellow gold contains silver and copper, with no nickel: it is hypoallergenic and develops a warm patina over time. White gold is alloyed with palladium (sometimes with nickel in older formulations or those produced outside the European Union): visually close to Platinum, it may require regular rhodium plating to maintain its silvery brilliance. Rose gold owes its colour to a proportion of copper of 20 to 25%: romantic and contemporary, it can be worn alone or layered with other gold tones.

Our Platinum is the ultimate benchmark. 95% pure (with 5% iridium or ruthenium for resilience), it is hypoallergenic, the very metal used in medical implants. Denser than gold, it develops a natural satin patina over time without wearing away. Visually identical to white gold, it carries a higher upfront cost, yet endures across generations without compromise.

Vermeil is an elegant option: a layer of gold at least 5 microns thick (per French standards) over a solid 925 silver core. Less durable than solid gold since the gold layer eventually wears with daily friction, vermeil delivers the look of gold at a different price point. At Mayuri, vermeil is part of our collection, yet 18ct gold remains our preferred recommendation for an engagement ring, a piece worn every day for decades.

European REACH regulations require a nickel release rate of no more than 0.5 micrograms per square centimetre per week for jewellery in prolonged contact with the skin. That said, the legal threshold is no guarantee of comfort for sensitive skin.

At Mayuri, none of our alloys contain nickel: yellow gold, white gold, rose gold, Platinum, and vermeil are all nickel-free, well below the regulatory limit. If you have a known sensitivity, Platinum remains the most inert material available, with a lasting aesthetic advantage: it does not yellow, unlike white gold, which may require periodic rhodium plating to maintain its silvery brilliance. Be cautious with jewellery of uncertain origin, as certain older formulations or pieces produced outside the EU may contain nickel. Vermeil (925 Silver with gold) is generally well tolerated, though silver can oxidise when exposed to perspiration and cosmetics, leaving a temporary discolouration on the skin, reversible and not harmful. For a ring worn continuously, our recommendation is solid gold or Platinum.

The solitaire is the most refined of all settings: a single stone set on a clean, understated band, typically held by four or six prongs. This simplicity draws all light and all meaning toward the stone itself. Nothing distracts from it, nothing competes with it. The solitaire endures across decades without ever feeling dated: it embodies commitment in its purest form.

The setting may vary (fine or sculpted prongs, a flat or domed band, a raised or flush-set stone), yet the principle remains the same: the stone speaks for itself. This is the choice of those who want a ring that is instantly recognisable, timeless by design, and that pairs harmoniously with a wedding ring when the moment comes. The solitaire is not an empty convention; it is a geometry that has stood the test of time. The central stone catches the light from every angle, the band disappears visually, and the finger carries a single point of light. No embellishment, no statement. Just the essential. Our Saral collection embodies this perfectly: Saral a slender 18ct yellow gold band, a four-prong set stone, nothing more.

Pavé features small stones along the band, creating a continuous line of light. More spectacular than a solitaire, pavé requires regular maintenance, as the grain-set stones may loosen over time. It is a setting for those who love maximum brilliance.

The halo surrounds the central stone with a crown of small diamonds or fine gemstones. Visually, it enlarges the central stone and amplifies its radiance. The halo was highly popular in the 1920s (Art Deco), then again in the 2010s. Today, it is making a strong comeback in more understated versions, featuring a single row of fine stones rather than an elaborate double halo.

The trilogy (or three-stone ring) features three stones along the band: one larger central stone flanked by two smaller side stones. The classic symbolism associates these three stones with the past, present, and future of the couple. Geometrically, the trilogy offers an elegant visual balance, more assertive than a solitaire yet less ornate than a full pavé setting.

Each setting tells a different aesthetic story. The choice comes down to your personal taste, your lifestyle (a pavé ring scratches more easily than a simple solitaire), and your budget: more stones means a higher price.

The price of a ring encompasses far more than raw materials: the work of the goldsmith and gemologist, the design, the sampling, the structure. Gold and the stone account for 30 to 50% of the final price. For reference: a 0.5 to 1 carat Diamond in 18ct Yellow Gold typically falls between £2,500 and £7,000, a coloured gemstone of 1 to 2 carats between £2,200 and £5,000, and bespoke pieces start from around £750. As for the "two to three months' salary" rule, that is a De Beers slogan, not a standard: the right budget is simply one that does not put you in debt. We break down 2026 price ranges item by item in our budget guide.

Proposing with a surprise requires knowing the ring size without raising suspicion. Five tried-and-true methods work well: borrowing and tracing the outline of a ring she already wears, having it measured at a jeweller, discreetly asking a close friend or family member, using a printable ring sizer, or purchasing in a standard size (52 to 54) and adjusting after the proposal. A ring that is too large slips away; a ring that is too tight cannot be worn: the detail makes all the difference, and each method has its pitfalls. We walk you through them one by one, complete with a size conversion chart, in our dedicated guide.

Confusion is common: both mark a commitment. A promise ring expresses a bond without a wedding date, earlier in the relationship, with a free-spirited aesthetic and a gentler budget. An engagement ring answers the question "will you marry me?" and opens the path to wedding planning: it is the centrepiece, the piece meant to be passed down. Both journeys, promise ring followed by engagement ring, or engagement ring from the outset, are equally valid. Meaning, styles, finger, budget: everything is covered in our dedicated guide.

There is no universally right moment. Christmas, Valentine's Day, or a birthday offer a natural setting for a proposal, but spontaneous proposals, an ordinary morning, a place that means something to you both, are just as meaningful: the right moment is the one where the decision feels clear to both of you. No minimum length of relationship is required, and choosing the ring together, trying it on as a couple before a surprise proposal on the chosen date, is now just as common as a complete surprise.

Tradition holds that the man gives the ring: a convention from the nineteenth century, when marriage was also an economic contract. There is nothing obligatory about it anymore. Some couples choose together, share the cost, or reverse the roles; a woman can give a ring to her partner, and our Mars collection exists for exactly that. What remains true: it is the person who proposes who presents the ring, regardless of whose hands paid for it.

A logistical detail many couples discover too late: a bespoke ring takes 4 to 6 weeks to craft, and longer before Christmas and Valentine's Day when our ateliers are fully booked. For a Christmas proposal, place your order in October. The proposal date is best chosen with the production timeline in mind.

A bespoke engagement ring is not a luxury indulgence. It is the opportunity to translate a singular story into a one-of-a-kind piece. Where ready-to-wear collections offer tried-and-tested combinations (blue Sapphire and white gold, Ruby and yellow gold, Diamond and Platinum), bespoke opens up every possibility.

You can choose an unusual coloured gemstone: an Emerald from our Canopée gradient Canopée (ranging from deep green to pale green, including tsavorite), a Sunset Sapphire (orange-toned) in place of the classic blue, or a fancy Diamond (yellow, champagne, cognac) rather than a pure white stone. You can combine metals (a yellow gold band with white gold claws, or Platinum paired with rose gold for a subtle contrast). You can engrave a date, initials, GPS coordinates, or a short phrase on the inside of the band, invisible from the outside, intimate for you both.

A bespoke piece begins with a conversation with our team: sketches, and an exchange of ideas on proportions and stone selection. Production lead times range from 3 to 8 weeks depending on the complexity of the project. Prices start from around £750 and increase according to your choices. What you receive in return is a piece that exists nowhere else in the world, created for you, for your story, for the hand that will wear it.

And if your project is a surprise and you are unsure of the size, we have thought of that too: our sizing guide has everything you need.

An engagement ring is chosen through both emotion and objective criteria: the stone (diamond or coloured), the metal (18ct gold, Platinum, or vermeil), the setting (solitaire, pave, halo, or trilogy), the budget (encompassing far more than raw materials), the size (measured with care), and the personalisation (bespoke or ready-to-wear). There is no standard formula, no universal rule. Every couple writes their own version.

Our collections feature all the major stones: Diamond, Ruby, Sapphire, Emerald, Black Diamond. Our settings range from the most refined solitaires to the most intricately crafted trilogies. Our metals include 18ct gold (yellow, white, and rose), Platinum, and vermeil. If no ring in our collections perfectly matches what you have in mind, we design fully bespoke pieces, from the selection of the raw stone through to the final engraving.
