Half-Bezel Radiant Cut Lab-Grown Diamond Engagement Ring with Hidden Diamonds 2.78tcw 14kt Yellow Gold

This Half-Bezel Radiant Cut Lab-Grown Diamond Engagement Ring centres a 2.50ct radiant-cut lab-grown diamond in DEF colour and VS clarity, with 0.28 total carat weight of round-cut lab-grown diamond accents set as hidden diamonds along the gallery for a total of 2.78 carats across the ring. The half-bezel setting wraps the centre stone on two sides while leaving the other two open for maximum light entry, the split-shank band visually elongates the finger while supporting the substantial centre stone. Lab-grown diamonds are openly disclosed as such throughout this listing, the centre and accents are real diamond material (the same chemistry, the same Mohs 10 hardness, the same optical properties as mined diamonds) produced in laboratory conditions rather than mined from the earth, sold honestly at a price tier that natural diamonds of comparable specification cannot match.

About the Lab-Grown Diamonds

The 2.50ct centre stone and the 0.28tcw of accent stones are all lab-grown diamonds (also called lab-created, synthetic, or laboratory-grown diamonds). Lab-grown diamonds are real diamonds, the same chemical composition (pure carbon arranged in a cubic crystal lattice), the same Mohs 10 hardness (the hardest natural material on earth), and the same optical properties (refractive index, dispersion, brilliance) as mined diamonds. The difference is origin: mined diamonds form geologically over billions of years deep in the earth, lab-grown diamonds are produced in controlled laboratory conditions over weeks via either Chemical Vapour Deposition (CVD) or High Pressure High Temperature (HPHT) processes. The result is real diamond material rather than a simulant like cubic zirconia or moissanite. The DEF colour grade on the centre stone places it in the colourless tier of diamond colour grading (the top tier), the VS clarity grade indicates very slightly included (a strong fine-jewelry clarity, with inclusions visible only under 10x magnification). DEF / VS specifications combined with 2.50ct centre weight and 0.28tcw accents is a top-tier lab-grown diamond engagement ring specification.

About the Half-Bezel, Split-Shank, and Hidden Diamonds

Three distinct setting features come together in this ring. The half-bezel centre setting wraps the radiant-cut centre stone on two opposing sides (typically the longer sides of the radiant shape) while leaving the other two sides open, the result combines bezel-setting protection (the metal collar guards the most exposed corners of the stone) with prong-setting brightness (the open sides allow light entry and reduce metal coverage). The split-shank band divides into two separate strands as it approaches the centre stone, the visual effect adds width and architectural detail to the band while supporting the substantial centre weight. The hidden diamonds feature places 0.28tcw of round-cut lab-grown diamond accents on the gallery (the under-bridge of the ring, visible only from the side rather than from the top-down view), creating a sparkle reveal when the ring is viewed in profile that's invisible from straight on. Hidden halos are a recognised contemporary design feature in fine engagement rings, the surprise side-view sparkle is part of the appeal.

Why Lab-Grown Diamonds for Engagement Rings

Lab-grown diamonds have become an increasingly mainstream choice for engagement rings over the past decade, the technology has matured to produce diamonds gemologically indistinguishable from mined diamonds at every grade level, and the price differential (typically 30-50% below natural diamonds of comparable specification) makes higher carat weights and stronger colour and clarity grades accessible at engagement-ring price tiers that natural diamonds rarely match. A 2.50ct natural diamond in DEF colour and VS clarity would price into the five-figure range before the setting; the same specification in lab-grown diamond keeps the centre stone substantial while leaving budget for design features (the half-bezel setting, the split-shank, the hidden diamonds) rather than committing all of it to the centre stone. For buyers prioritising visual impact, design quality, and ethical sourcing over the long-term store-of-value argument for natural diamonds, lab-grown is the path that fits engagement-ring purposes most efficiently. We disclose the lab origin openly throughout this listing, in the product name, in the spec sheet, in the FAQ, and in the schema, rather than letting buyers discover the lab origin only after purchase.

Frequently Asked Questions

Are these natural diamonds or lab-grown diamonds?

Lab-grown diamonds. Both the 2.50ct radiant-cut centre and the 0.28tcw of round-cut accents are lab-grown (also called lab-created or laboratory-grown) diamonds. Lab-grown diamonds are real diamonds, the same chemistry (pure carbon in a cubic crystal lattice), the same Mohs 10 hardness, and the same optical properties as mined diamonds. The difference is origin: mined diamonds form geologically over billions of years, lab-grown diamonds are produced in controlled laboratory conditions over weeks via CVD or HPHT processes. They are NOT cubic zirconia, moissanite, or any other diamond simulant. We disclose this openly throughout the listing.

What does 'hidden diamonds' mean on this ring?

Hidden diamonds (sometimes called hidden halo) refers to the 0.28tcw of round-cut lab-grown diamond accents set on the gallery, the under-bridge portion of the ring that's visible from the side but invisible from the top-down view. The effect is a surprise sparkle reveal when the ring is viewed in profile, distinct from a traditional halo where the accent stones encircle the centre stone visibly from above. Hidden halos are a recognised contemporary engagement ring design feature.

How does DEF colour and VS clarity compare to other diamond grades?

DEF is the colourless tier of diamond colour grading, the top tier (D, E, F all read as completely colourless to the unaided eye). G, H, I are 'near colourless', J onward begin to show faint colour tints. VS (very slightly included) is in the upper range of clarity grading, two tiers below FL/IF (flawless / internally flawless) but two tiers above SI (slightly included). DEF/VS is considered top-tier specification for fine engagement rings, the diamonds will appear bright and white with no visible inclusions to the unaided eye.

What is a half-bezel split-shank setting?

Two separate setting features on this ring. Half-bezel refers to the centre stone setting style: a metal collar wraps the centre stone on two sides (leaving the other two sides open), combining bezel-setting protection with prong-setting light entry. Split-shank refers to the band style: the band divides into two separate strands as it approaches the centre stone, adding visual width and architectural detail. Together with the hidden diamonds on the gallery, these three features give the ring its distinctive contemporary character.
