Twenty-eight engagement rings, from $120 to $1,909, with most sitting between $480 and $900. Fifteen are diamond-centred and eleven are coloured gemstone designs, which is a much higher proportion of coloured stones than a conventional engagement range — and it is the most useful thing to know before you start.
Every diamond here is lab-grown. That is the second thing worth knowing, because it is what makes the price range possible.

Lab-grown diamonds, and what they change
A lab-grown diamond is a diamond. Same chemical composition (pure carbon), same crystal structure, same hardness, same refractive index, same behaviour under light. Distinguishing one from a mined stone requires specialist equipment, not a jeweller's loupe. The only difference is how it formed.
What that means in practice is the entire reason this price range looks the way it does. A lab-grown stone costs substantially less than a mined one of the same size and clarity, which puts a visibly larger or cleaner centre stone inside a given budget. For most buyers here, the choice is not between a lab diamond and a mined diamond at the same price — it is between a lab diamond and a noticeably smaller mined one.
It is worth deciding in advance how you feel about origin, because it is the one thing that genuinely differs. Some people care about a stone having geological history; most, when they understand there is no physical difference, do not. See diamond vs lab diamond.
Coloured stones as centre stones
Eleven of the twenty-eight rings here are coloured gemstone designs, and this is a real alternative rather than a budget option.
Sapphire is the strongest choice and appears in ten pieces. It is the hardest coloured stone in this catalogue, second only to diamond, which matters more for an engagement ring than for anything else — this is a ring intended to be worn every day for decades. Beyond classic blue there are teal sapphires and padparadscha, a pinkish-orange variety.
Topaz, tourmaline, morganite, opal and zultanite appear in the marquise range, giving colours nothing else here offers — mint, peach, lilac, smoky grey, ice blue. These are softer stones. A morganite or opal engagement ring is beautiful and needs to come off for manual work; it is not a stone-and-forget purchase.
Emerald appears in one piece here. Emeralds contain characteristic internal inclusions that make them more brittle than their hardness suggests, which makes emerald a demanding choice for a ring worn permanently.
A coloured centre stone costs less per carat than a diamond and carries a personal marker a diamond does not. The honest trade-off is durability, and it is worth deciding which you are optimising for.
Shape, and how it affects perceived size
Pear, marquise, oval, emerald cut, princess and cushion shapes all appear here.
Elongated shapes — oval, pear, marquise — look larger than round stones of the same carat weight, because they spread more surface area across the finger rather than depth beneath it. They also extend the visual line of the finger. If size within a budget is your priority, this is the most effective single lever.
Round stones return the most light and are the most forgiving of inclusions, because brilliance masks them.
Step cuts — emerald cut and baguette — trade sparkle for a cleaner, more architectural look with broad flashes rather than fine scintillation. They show inclusions more readily than brilliant cuts, so clarity matters more in a step-cut stone.
Marquise and pear have points, and points are the vulnerable part of any stone. A setting that protects the point — a V-prong or bezel — is worth looking for.
Settings
Solitaire prong is the largest group here at fifteen pieces. It lifts a single stone so light enters from all sides, giving maximum brilliance. Prongs catch on fabric and need checking every few years; a lost stone is nearly always a prong that had loosened.
Bezel wraps the stone in a rim of metal. It is the practical choice for anyone who works with their hands, plays sport, or has small children — nothing catches, and the stone edge is protected. Four pieces here are bezel-set. The trade-off is slightly less light entering the stone.
Cluster settings group several small stones to read as one larger one, giving presence for less money.
Toi et moi places two stones side by side, a nontraditional alternative with obvious symbolism.
Thinking ahead to the wedding band
This is the decision people most often postpone and most often regret postponing.
The setting profile of the engagement ring determines what band can sit flush against it. A raised solitaire leaves a gap beside a straight band, and the two rings then rock against each other and wear each other's metal down over years. A curved or chevron band nests around the setting; a V-shaped band does the same for pear and marquise stones.
A bezel or low-set engagement ring is the most flexible, because a plain straight band sits against it without a gap.
You do not need to buy both at once. You do need to know, when choosing the engagement ring, whether you are also committing to a shaped band later. See wedding bands.
Sizing, and why it matters most here
Every ring is made to order, so size is fixed at production. For a proposal ring this is the highest-stakes sizing decision in the catalogue, and it is often being made for someone else without their knowledge.
Most designs run US 4 to 8.5 including half sizes. The reliable method for a surprise is to borrow a ring they already wear on the same finger of the same hand and measure its internal diameter — not a ring from a different finger, which will be a different size. Fingers on the dominant hand are typically slightly larger.
If measuring directly: wrap paper around the base of the finger, mark the overlap, measure in millimetres, then do the same over the knuckle and take the larger. Measure at the end of the day. See the size guide and how to measure your ring size.
Metal, care and ordering
These are solid gold — 14k at 58.3% purity, with the entry tier hallmarked 9K in the UK and Europe and 10K in the US. The gold runs throughout, so the ring can be repolished and repaired for decades, which is the point for a piece worn permanently.
Have prongs checked every few years. Never use an ultrasonic cleaner on emerald, opal or morganite. Keep gold away from chlorine. See the care guide.
Production is 4–6 business days before dispatch. US orders ship from Connecticut with duties included; UK, EU, Canada and Australia orders from London. 365-day warranty. Engraved rings cannot be returned. See shipping and returns.
Frequently asked questions
Are lab-grown diamonds real diamonds?
Yes. Identical chemical composition, crystal structure, hardness and optical behaviour to mined diamonds. Telling them apart requires specialist equipment. Only the formation differs.
What is the price range for engagement rings here?
$120 to $1,909, with most sitting between $480 and $900. Lab-grown stones are what make that range possible.
How do I get the largest-looking stone for my budget?
Choose an elongated shape — oval, pear or marquise. They spread more surface area across the finger than a round stone of the same carat weight, so they read larger.
Is a sapphire engagement ring practical?
Very. Sapphire is the hardest coloured stone here, second only to diamond, which matters for a ring worn every day for decades. Softer stones like morganite and opal need to come off for manual work.
How do I find their ring size without asking?
Borrow a ring they already wear on the same finger of the same hand and measure its internal diameter. A ring from a different finger will be a different size.
Should I buy the wedding band at the same time?
Not necessarily, but decide the shape question now. A raised solitaire needs a curved or chevron band beside it; a straight band leaves a gap and the two rings will wear against each other.
Which setting is best if she works with her hands?
Bezel. The metal rim wraps the stone, nothing catches on fabric, and the stone edge is protected. The trade-off is slightly less light entering the stone.
Do marquise and pear stones chip?
The points are the vulnerable part of any pointed shape. Look for a V-prong or bezel setting that protects the point rather than leaving it exposed.
Can an engagement ring be resized later?
Plain-shanked designs are the most straightforward. Heavily stone-set shanks are the most constrained. Because everything is made to order, getting the size right up front matters more here than anywhere else.
What is the difference between an engagement ring and a promise ring?
An engagement ring signals an intended marriage and is traditionally worn on the left ring finger. A promise ring signals commitment without a wedding date and can be worn on any finger. They are not interchangeable.
