Three Decisions, Made With Intention
Most engagement rings are the result of one decision: pick the stone, and the rest follows from a catalog. This one is the result of three.
The first was the cut: a radiant, the elongated rectangular shape with cropped corners and seventy facets that combines the architectural geometry of an emerald cut with the fire of a round brilliant. The second was the setting: a half-bezel, where solid metal wraps the long sides of the stone and leaves the rest of it open to light. The third — and this is the one nobody else does — was to set hidden diamonds into the shoulders of the band, where they're invisible from above but catch light when the wearer turns the ring.
Three small refusals to do the obvious thing. Three deliberate departures from the engagement-ring catalog. Together, they make the ring you see below.
The Detail You Don't See at First
Most engagement rings hide nothing.
This one hides this.
Hidden Diamonds · Set Into Both Shoulders of the Shank
From above, the piece reads as a clean half-bezel solitaire — radiant cut center stone, white-gold mounting, no obvious flourish. Turn it ninety degrees, and the second story emerges: small bezel-set diamonds running along the inside curve of the shank, only visible from the side, only there for the wearer to find. It's the kind of detail that distinguishes a ring designed by a person from one designed by a stock template.
On the Hand
How It Lives
The clean studio shots tell you what the ring is.
These tell you how it actually wears.
The Cut
What Is a Radiant Cut Diamond?
The radiant cut was patented in 1977 by Henry Grossbard, who set out to design a fancy-shape diamond that delivered the same brilliance as a round brilliant cut. He succeeded. With seventy facets — more than an emerald cut's fifty-eight, more than a princess cut's fifty-seven — the radiant cut returns light from a wider range of angles than almost any other fancy shape on the market.
Visually, a radiant cut diamond engagement ring looks like an emerald cut and behaves like a round. The cropped corners give the stone the architectural silhouette of an emerald cut — clean, geometric, modern. The seventy facets give it the fire of a round — sparkle that catches light from across a room.
Two practical advantages worth knowing: radiants cost 20–30% less per carat than rounds of equivalent quality grade (because the cut wastes less of the original rough), and they look larger on the finger than rounds of equivalent carat weight (because the elongated rectangular shape covers more surface area). For a buyer who wants size and brilliance without paying the round-brilliant premium, radiants are the answer.
The Setting
What Is a Half-Bezel Setting?
A bezel is a band of metal that wraps around the edge of a gemstone, holding it in place from the outside rather than from above (as prongs do). A full bezel wraps the metal completely around all four sides; a half-bezel wraps only the long sides, leaving the cropped corners exposed.
The compromise is intentional. A full bezel is the most secure setting in fine jewelry — the metal protects the diamond's edges from chips and impact — but it also dims the stone's brilliance by blocking light from entering through the sides. A half-bezel keeps the protection where the stone is most vulnerable (the corners and long edges) while leaving the open sides for light to flood through.
For a radiant cut specifically, the half-bezel setting does something extra: it accentuates the elongated silhouette. The metal frames the long sides of the stone like a parenthesis, drawing the eye along the length of the diamond and making the ring read as more graceful, less square. It's why half-bezel radiants photograph so well in profile.
The Signature Detail
What Are "Hidden Diamonds"?
Hidden diamonds — sometimes called a hidden halo, a surprise halo, or simply "diamonds where you don't expect them" — are accent stones set into the side or underside of the engagement ring rather than the top. They're invisible from the head-on view that most engagement ring photography captures. They only reveal themselves from the side, from below, or in close-up detail.
On this piece, the hidden diamonds run along the inside curve of both shoulders of the shank — set into bezels themselves, securely flush with the band, catching light only when the wearer turns her hand. The effect is quietly extravagant: the ring rewards closer inspection. The person wearing it gets to discover (and re-discover) the detail that nobody else can see.
It's the closest thing fine jewelry has to a private joke between the maker and the wearer. Every ring is also an object you live with — you look at it constantly, on the subway, washing dishes, holding a phone. A hidden diamond detail gives that constant looking something new to find every time.

Why This Ring, Now
There are two kinds of engagement rings worth buying. The first is the classic — a single round brilliant on a thin platinum band, the silhouette every grandmother recognizes, the safest possible visual choice. There's nothing wrong with it. There's also nothing surprising about it.
The second kind is the one that has a small editorial point of view. Not "different for the sake of different" — just designed by a person who made deliberate decisions about cut, setting, and the small invisible detail that nobody else thought to add. This ring is squarely in that second category.
The radiant cut delivers the architectural silhouette of an emerald with the brilliance of a round. The half-bezel protects the stone where it's vulnerable while keeping the sides open for light. The hidden diamonds reward the wearer for paying attention. The 14kt gold construction is solid, daily-wearable, and made by a working bench team you can email today.
It's the ring for someone who already knows she doesn't want what everyone else has — and who'll quietly enjoy showing the side view to people who notice.
Frequently Asked Questions
What is a radiant cut diamond?
A square or rectangular diamond with cropped corners and 70 brilliant facets, patented in 1977. Combines the silhouette of an emerald cut with the fire of a round brilliant. Costs 20–30% less per carat than rounds of equivalent quality.
What is a half-bezel setting?
Solid metal wraps two opposite edges of the stone (typically the long sides) while leaving the other two edges exposed. More secure than prong setting, more open than full-bezel setting.
What are hidden diamonds on an engagement ring?
Small accent diamonds set into the side or underside of the band, visible only from profile or in detail shots. The ring featured here has hidden diamonds set into both shoulders of the shank.
How big does a 2.78 carat radiant cut diamond look?
Approximately 9 × 7 mm. Reads as a substantial statement stone — closer to a 3-carat round than a 2-carat round in visual impact, because the elongated rectangle covers more surface area.
Is a radiant cut diamond more expensive than a round?
No. Radiants typically cost 20–30% less per carat than rounds of equivalent grade. Rounds waste more rough during cutting, which is why they carry a premium.
Are radiant cut engagement rings popular in 2026?
Yes — they've grown faster than any other fancy-shape diamond in the last three years. Better price-per-carat than rounds, modern silhouette, brilliance that competes with rounds.
How much does this ring cost?
Starts at $1,575. Final price varies by ring size and any custom modifications.
What's the difference between a half-bezel and a full bezel?
Full bezel wraps all four edges of the diamond. Half-bezel wraps only two edges. Full bezels are most secure but dim brilliance; half-bezels balance protection and light.
Can this ring be resized?
Yes. One free resize within 60 days. Half-bezel and hidden-diamond settings can be resized within reasonable limits (1–2 sizes); larger changes may require remounting.
