Things to Consider When Picking an Engagement Ring
Choosing an engagement ring is one of the most personal decisions a buyer can make. An antique or vintage ring offers something no modern jeweller can replicate — a piece with its own history, hand-finished craftsmanship, and character that has already endured decades or centuries of daily wear. This guide covers the practical considerations that matter most: gemstones, settings, metals, hallmarks and sizing.
Why Did Diamonds Become the Standard Engagement Ring Stone?
Diamonds were not always the default choice for engagement rings. The earliest well-documented diamond betrothal ring dates to 1477, when Archduke Maximilian of Austria presented one to Mary of Burgundy, though the British Museum notes this tradition's origins remain uncertain. Before the mid-twentieth century, engagement rings commonly featured coloured gemstones, pearls and miniature diamonds.
The shift came in 1947, when De Beers' copywriter Frances Gerety coined the slogan "A Diamond Is Forever." Before that campaign, only around 10% of American brides received diamond engagement rings. By 1990, the figure had reached 80%. The Tiffany solitaire setting, introduced in 1886 by Charles Lewis Tiffany, had already established the raised-diamond archetype — but it was De Beers' marketing that made diamonds feel obligatory.
Which Gemstones Are Best for Everyday Wear?
Diamond, sapphire and ruby are the most practical gemstones for an engagement ring worn daily. Diamond scores 10 on the Mohs hardness scale, while sapphire and ruby both score 9, making all three highly resistant to scratching.
Hardness alone does not tell the full story. The Mohs scale measures scratch resistance, not toughness — a stone's ability to resist fracture or chipping. Emerald scores 7.5-8 on the Mohs scale but is classified by the GIA as a Type III gemstone, meaning it almost always contains natural inclusions that make it brittle. Its toughness rating is only "fair to good." An emerald engagement ring can work, but it needs a protective setting and more careful handling than a diamond or sapphire.
| Gemstone | Mohs Hardness | Toughness | Daily Wear Suitability |
|---|---|---|---|
| Diamond | 10 | Excellent | Ideal |
| Sapphire | 9 | Excellent | Ideal |
| Ruby | 9 | Excellent | Ideal |
| Emerald | 7.5-8 | Fair to good | With care |
| Opal | 5.5-6.5 | Poor to fair | Occasional wear |
| Pearl | 2.5-4.5 | Good | Occasional wear |

What Makes Antique Diamonds Different from Modern Ones?
Antique diamonds were cut entirely by hand, producing stones with individual character that machine-cut modern diamonds cannot replicate. The old mine cut — the dominant diamond cut from the early eighteenth to late nineteenth century — has 58 facets like a modern brilliant cut, but with a squarish outline, smaller table, higher crown, larger culet and shorter lower half facets.
Each old mine cut diamond is unique because it was shaped by a bruter who ground two diamonds together, following the natural octahedral crystal form, before a polisher finished the facets. According to the GIA, old mine cuts display less brilliance but more fire — the spectral colour dispersion that produces bold flashes of colour — than modern round brilliants. Under candlelight or low lighting, these diamonds come alive in a way that modern cuts do not.
| Diamond Cut | Era | Shape | Key Characteristics |
|---|---|---|---|
| Rose cut | Pre-1760s, Georgian | Domed top, flat base | Triangular facets, no pavilion, subtle sparkle |
| Old mine cut | 1700s-1890s | Soft cushion | High crown, large culet, bold fire |
| Old European cut | 1890s-1930s | Round | Smaller culet, precursor to modern brilliant |
| Modern brilliant | 1919 onwards | Round | 57-58 facets, maximum brilliance |
How Does the Setting Affect an Engagement Ring?
The setting determines both how the gemstone looks and how well it is protected during daily wear. A bezel setting, which encases the stone's edge in a metal rim, offers the most protection and sits lower on the finger — a practical choice for active lifestyles. A claw or prong setting raises the stone higher, allowing more light to enter and increasing sparkle, but the claws need periodic checking to ensure they remain secure.
Cluster settings, which group smaller stones together to create the impression of a larger gem, were particularly popular in the Georgian and Victorian periods. The solitaire — a single stone in a raised setting — became the defining engagement ring style after Tiffany's 1886 innovation, though antique solitaires use collet and claw settings rather than the modern six-prong version.
| Setting Type | Protection Level | Light Performance | Historical Period |
|---|---|---|---|
| Bezel/collet | High | Moderate | Georgian onwards |
| Claw/prong | Moderate | High | Victorian onwards |
| Cluster | High | Moderate | Georgian, Victorian |
| Gypsy/flush | Very high | Low | Victorian, Edwardian |
| Pavé | Moderate | High | Edwardian, Art Deco |
What Metal Should You Choose for an Engagement Ring?
Gold is the most common metal in antique engagement rings, and hallmarks inside the band can date a ring with precision. British hallmarking of gold dates back to 1300, when Edward I's statute required a leopard's head mark — making it one of the oldest forms of consumer protection in the country.
Lower carat gold standards — 9ct, 12ct and 15ct — were only introduced in 1854. The 12ct and 15ct standards were cancelled in 1932 and replaced by 14ct. This means a British-hallmarked ring in 15ct gold dates between 1854 and 1932, while anything hallmarked before 1854 will be 18ct or 22ct. Lower carat gold is harder and more scratch-resistant; higher carat gold is softer but has a richer colour and greater intrinsic value.
Platinum became widely used in engagement rings during the Edwardian period (1901-1915), prized for its strength and white colour. It allowed jewellers to create delicate, lace-like settings that would have been impossible in gold. Explore our hallmark finder for help identifying the marks inside your ring.
How Do You Find the Right Ring Size?
The UK uses an alphabetical sizing system (running from A to Z+), while the US uses a numerical system. A UK size L corresponds roughly to US size 6, and a UK size O to US size 7. The most reliable method is to visit a jeweller with a set of ring sizers — a collection of metal bands in every size — and try them on the finger that will wear the ring.
Common mistakes include measuring at the wrong time of day (fingers swell in warm weather and toward the evening), using a ring that is worn on a different finger as a guide, and relying on string or paper strip methods that tend to be inaccurate. For antique rings, sizing is especially important because some older pieces have thicker shanks that fit differently from modern rings. Our guide to ring sizing and resizing for antique pieces covers this in detail.
Are Antique Engagement Rings a Sustainable Choice?
Choosing an antique engagement ring is one of the most environmentally responsible decisions a buyer can make. No new mining is required — the ring already exists. According to Earthworks, an environmental research organisation, producing the gold for a single new ring generates more than 20 tonnes of mine waste. The Smithsonian Magazine independently corroborates this figure, noting that 20 tonnes of rock and soil are dislodged to produce enough raw gold for one ring.
An antique ring carries none of this environmental cost. The materials were extracted decades or centuries ago, and every year the ring continues to be worn is a year no new resources are consumed. Beyond the environmental case, antique rings also offer craftsmanship that is not replicated in modern mass production — hand-finished details, hand-cut diamonds and individually worked settings.
How Should You Choose a Style That Fits?
An engagement ring should reflect the wearer's personality, not follow a trend. Antique and vintage rings span centuries of design — from the closed-back settings and foil-backed stones of the Georgian era, through the romantic sentiment of Victorian jewellery, to the geometric precision of Art Deco. Each period produced distinctive engagement ring styles.
Consider how the ring will look alongside a wedding band. Some antique ring settings — particularly cluster designs and wide boat rings — sit high on the finger and may not pair easily with a flat band. A solitaire or low-set collet ring typically sits flush with a band. Think about the wearer's daily routine, too: someone who works with their hands will find a low-set bezel or gypsy setting more practical than a raised claw mount.

Frequently Asked Questions
What is the best gemstone for an engagement ring worn every day?
Diamond, sapphire and ruby are the most durable choices for daily wear. Diamond scores 10 on the Mohs hardness scale, while sapphire and ruby both score 9. These three gemstones combine high scratch resistance with excellent toughness, meaning they resist both scratching and chipping. Softer stones like opal and pearl are better suited to occasional wear or protective bezel settings.
How can British hallmarks help date an antique engagement ring?
British hallmarks have been stamped inside gold rings since 1300. The marks identify the maker, the assay office that tested the gold, and the date of hallmarking through a system of date letters. A ring in 15ct gold must date between 1854 (when that standard was introduced) and 1932 (when it was cancelled). An 18ct or 22ct hallmark on its own does not narrow the date, since these standards predate 1854.
What is the difference between an old mine cut and a modern brilliant cut diamond?
Both have 58 facets, but old mine cuts have a squarish outline, higher crown, smaller table and larger culet. They were hand-cut by bruters who shaped each stone individually, following the natural crystal form. According to the GIA, old mine cuts display less brilliance but more fire — producing bold flashes of spectral colour rather than the white sparkle of modern brilliants.
Are antique engagement rings more environmentally friendly than new ones?
Antique rings require no new mining. Earthworks estimates that producing the gold for a single new ring generates more than 20 tonnes of mine waste, a figure corroborated by the Smithsonian Magazine. By choosing an antique ring, the buyer avoids this environmental footprint entirely while acquiring a piece with craftsmanship that predates modern mass production.
Should I choose gold or platinum for an antique engagement ring?
Gold is the most common metal in antique rings, available in 9ct, 15ct, 18ct and 22ct purities. Lower carat gold is harder and more durable; higher carat gold has a richer colour. Platinum became popular during the Edwardian period and is valued for its strength and white colour, but antique platinum rings are rarer and typically more expensive than gold equivalents.
How do I find my partner's ring size without them knowing?
Borrow a ring they already wear on the correct finger and take it to a jeweller for measurement. Alternatively, press the ring into a bar of soap to capture an impression. Avoid string or paper strip methods, which are unreliable. Remember that fingers swell in warm weather and throughout the day, so an ideal fit accounts for slight size variation.
