Lab Diamond Round Brilliant Cushion Halo Stud Earrings with Corner Accent Stones in 925 Sterling Silver

One round brilliant lab diamond, a full halo of white stones, and a cushion frame with corner accents — the stud that looks considerably larger than any single stone could explain.

These stud earrings use a cushion halo construction to achieve a visual face area and apparent diamond presence that the centre stone alone does not produce — and this is precisely the design’s purpose. The centre stone is a round brilliant lab-grown diamond set in four prongs, delivering the white light return and scintillation of the round brilliant cut. Around the centre stone, a continuous ring of closely-set round brilliant white stones forms a complete halo, amplifying the apparent diameter of the earring face and framing the centre diamond in a border of white brilliance. Beyond the halo, a cushion-shaped 925 sterling silver frame — a square with softly curved sides forming the cushion outline — provides the outer boundary of the earring, and at each of the four corners of the cushion frame, a round brilliant white stone is set as a corner accent, extending white stone coverage to the widest points of the earring and giving the cushion corners a finished, considered quality. The combination of centre diamond, continuous halo, and corner-accented cushion frame creates an earring face where white stone coverage extends from the centre prongs to the outer frame corners — the complete earring face is white stone from edge to edge. At $990, this is the most expensive piece in the LabGrownPro collection, and the cushion halo construction is what justifies the price: the total stone count, the precision required to set a continuous halo and corner accents in a consistent cushion frame, and the resulting visual face area place this earring in a different category from a simple round solitaire stud. The earring appears, at ear-glance distance, substantially larger than the centre stone’s actual diameter — the cushion halo’s primary function is to make a fine diamond stud as visually impactful as possible without requiring a larger centre stone.

Why You'll Love It

• Cushion halo construction — maximum visual face area from one centre stone — the centre round brilliant diamond, its full continuous halo, and the corner-accented cushion frame together create an earring face that reads substantially larger at ear-glance distance than the centre stone’s actual diameter; this is the cushion halo’s primary function — to amplify apparent earring size through stone coverage rather than stone carat weight; at $990, the visual impact of this earring is disproportionate to the centre stone size alone
• Full continuous halo — centre diamond framed in white brilliance — a complete ring of closely-set round brilliant white stones surrounds the centre diamond, tracing its circular outline and creating a uniform white brilliance border that the eye reads as part of the centre stone’s apparent diameter; the halo also increases the total number of light-catching facets at the earring face, creating more active sparkle across the full earring than a solitaire stud produces
• Cushion frame with corner accent stones — the 925 sterling silver cushion frame — a softly curved square outline — provides the outer boundary of the earring; at each of the four cushion corners, a round brilliant white stone is set as a corner accent, extending white stone coverage to the extremities of the earring face; the corner stones give the cushion shape a definition and a finished quality that an unset silver frame does not have, and they make the earring’s square-cushion silhouette read clearly at ear distance
• Round brilliant centre — the benchmark cut in the finest setting format — the round brilliant lab diamond at the centre is the highest-performing cut for white light return, fire, and scintillation; set in four prongs within the halo, its full table and upper facets are exposed to incoming light; in a halo setting, the centre stone’s performance is amplified by the surrounding halo’s reflected light, creating a brighter combined face than the centre stone alone produces
• The collection’s finest stud — for the occasion that warrants it — at $990 this is the most substantial earring in the LabGrownPro range; the cushion halo format is a classic of fine jewellery design — it has been used by the most recognised jewellery houses for decades because it works: it makes a diamond stud as visually commanding as its setting allows; for an engagement gift, a significant birthday, a personal milestone, or simply the earring that will be worn for decades, this is the right choice
