Find Your Perfect Diamond
Made to sit flush against the engagement ring it was designed for.
Every ring is made from start to finish in our Los Angeles atelier.
The emerald cut's outline with the round brilliant's engine inside. The radiant crops its corners for safety, fills its rectangle with crushed-ice fire, and forgives clarity and color more generously than almost any shape, the pragmatist's answer to wanting it all.
The radiant is a hybrid, engineered in the late 1970s to answer a specific question: could the emerald cut's elegant, cropped-corner rectangle carry the fire of a brilliant? Its inventor rebuilt the pavilion with brilliant-style faceting under a step-cut silhouette, and the result was the first rectangular shape to earn a brilliant's sparkle, a dense, glittering pattern the trade calls crushed ice.
The engineering pays out twice. First in resilience: the eight cropped corners remove every vulnerable point from the outline, making the radiant the most durable elongated shape in diamonds. Second in forgiveness: the crushed-ice faceting shreds inclusions and disperses body color so effectively that the radiant tolerates lower clarity and color grades than nearly anything else on the board.
Face up, a radiant reads as an emerald cut that swapped stillness for fireworks. Buyers deciding between the two are really choosing between architecture and energy, and the radiant is the honest recommendation whenever the budget concentrates on size and sparkle rather than grades.
| Facets | Typically 70, brilliant style in a rectangle |
| Cut grading | No formal lab cut grade, evaluate by eye |
| Face-up size | Generous spread, slightly under oval |
| Length to width | 1.15 to 1.35 rectangular, 1.00 to 1.05 square |
| Relative price | Among the lowest per carat of the major shapes |
| Watch for | The bow-tie, corner evenness, depth over 70 |
The radiant spreads well for its weight, close behind the oval, and its rectangle stretches nicely along the finger. Watch one number: depth. Radiants are sometimes cut deep to hold weight, and a stone over about seventy percent depth hides carats under the table where no one sees them.
| Carat Weight | Typical Measurements | How It Wears |
|---|---|---|
| 0.75 ct | 6.4 x 4.9 mm | A lively rectangle on slender hands |
| 1.00 ct | 7.0 x 5.4 mm | The classic radiant, dense with fire |
| 1.50 ct | 8.1 x 6.2 mm | Generous spread with crushed-ice glitter |
| 2.00 ct | 8.9 x 6.8 mm | Commanding presence, edge to edge sparkle |
| 3.00 ct | 10.2 x 7.8 mm | A statement rectangle across the finger |
Measurements are typical for well proportioned stones. Individual diamonds vary with their cutting.
The radiant is the shape where smart buyers save the most, because its faceting forgives what other shapes expose. Here is where your attention belongs.
Crushed-ice faceting is the best inclusion camouflage in diamonds: SI1 and even verified eye clean SI2 stones read flawless face up, and G to H color disappears in white metals, I in yellow gold. The radiant exists so you can put those savings into carat, and you should.
Two numbers do the work. Keep depth under roughly seventy percent so the weight you pay for shows on the finger, and confirm on video that any bow-tie across the center flickers rather than sits fixed. Elongated radiants carry the same bow-tie rules as ovals.
The eight cropped corners should match, even and symmetrical around the outline. Then watch the crushed ice itself: fine radiants glitter uniformly edge to edge, while poor ones show dull patches or a dead center. None of this appears on the certificate, only on video.

With no exposed points to guard, the radiant frees the setting to be pure style. These three directions cover most of what our clients choose, each made to order around your exact stone.
Four prongs and a clean band, all crushed ice on display. The radiant's durability makes this the rare elongated shape that needs nothing defensive from its mount.
Flanked by trapezoids or tapered baguettes, the composition the radiant was practically invented for. The step cut sides frame the brilliant center in deliberate contrast.
Pavé beneath the girdle, invisible face on, glowing in profile. Adds ceremony without interrupting the rectangle's clean sweep.
The radiant is the shape for buyers who read the price list before the poetry. It forgives the grades other shapes punish, and it puts the difference on the finger.
We will be straight about what the radiant is: the value engineer's elongated diamond. It was designed to combine the emerald cut's outline with the brilliant's forgiveness, and it succeeded so well that the honest advice is to buy its grades lower than pride prefers: an eye clean SI, an H in gold, and the carats those choices set loose. Its checks are few: depth under about seventy percent, a bow-tie that moves, corners cut even. What it does not offer is the emerald cut's stillness; crushed ice is energy, not architecture, and a buyer wanting the hall of mirrors should walk one page over and pay the step cut's grade bill knowingly. Between those two honest options, most size-first budgets belong here, and we will say so plainly when yours does.
