Elongated Radiant Moissanite Hidden Halo Engagement Ring

Elongated radiant-cut engagement ring with your choice of moissanite or lab-grown diamond, a low cathedral, four triple-claw corner clusters, and a restrained hidden halo. Designed as Jewel Eternal’s clean core radiant setting, it combines a solitaire-led face-up look with refined side detail, an open gallery, and a bridge designed to accommodate many straight wedding bands.

Each colorless Jewel Eternal moissanite is D color and VVS1 clarity or better. Choose a 2.5ct, 3ct, or 4ct center in 925 sterling silver, 14K gold over sterling silver, solid 14K yellow gold, solid 14K white gold, or Platinum 950 where offered.

Choose your center stone: Moissanite or lab-grown diamond in 2.5ct, 3ct or 4ct sizes. Lab-grown diamond centers are offered in solid 14K yellow gold, solid 14K white gold and Platinum 950. Select CENTER STONE, metal and ring size to see the finished-ring price.

Our lab-grown diamond selection target is D–F color and VS1 clarity or better, with proportions and make suited to the radiant shape. Exact stone specifications and any accompanying grading report are confirmed for the sourced center stone; a particular laboratory report or growth method is not guaranteed.

The center-stone selection changes the center only; the hidden-halo accents remain moissanite.

Center stone sizes

The setting is proportioned to the actual center stone rather than stretching one basket across every size. Approximate moissanite face-up targets are:

• 2.5ct: approximately 9.0 × 6.6 mm
• 3ct: approximately 9.5 × 7.0 mm
• 4ct: approximately 10.4 × 7.6 mm

Moissanite carat labels describe diamond-equivalent size. Lab-grown diamond carat labels refer to center-stone weight, not total ring weight. Diamond millimeter dimensions vary with the sourced stone and its proportions; the basket is fitted to that stone. The 3ct version is the signature proportion shown in most imagery.

Triple-claw prong setting

Each clipped corner is secured by a matching cluster of three petite claw tips. The four identical clusters create twelve visible claw tips in total, reinforcing the radiant’s geometry while keeping the center stone visually dominant.

Hidden halo and low cathedral

The hidden halo sits beneath the girdle and follows all four sides of the radiant, with only the structural interruptions required by the cathedral connections. It is intentionally subtle from above and becomes visible from side and three-quarter angles.

The solid cathedral shoulders rise into an open basket rather than a bulky enclosed cup. The architecture keeps the setting low to moderate while preserving center-stone security, cleaning access, and wedding-band clearance.

Wedding-band fit

The bridge is designed around a slim straight wedding band, with a target clearance suitable for a band approximately 2.0 mm wide and 1.8 mm high. Many straight bands should sit flush or nearly flush. Because wedding-band profiles vary, a very small gap may remain with some bands.

For a slim line of sparkle, explore the Micro Pavé Moissanite Half Eternity Band. Exact pairing clearance must be checked against the chosen band; this is not a guarantee of a flush fit. Browse more Jewel Eternal wedding bands.

Metal options

• 925 sterling silver: reinforced for the setting and finished in bright rhodium where specified.
• 14K gold over sterling silver: 925 sterling silver with extra-thick 3-micron 14K gold plating.
• Solid 14K yellow gold: warm, durable fine-jewelry construction and the signature gold version shown.
• Solid 14K white gold: a bright white-metal option with cohesive contrast around the colorless center.
• Platinum 950: naturally white, dense fine-jewelry metal with platinum-appropriate prong construction.

Made for everyday bridal wear

The approximately 2.2 mm plain shank avoids the fragile appearance of an ultra-thin band beneath a substantial radiant. Rounded claw tips reduce snag risk, the open underside allows access beneath the pavilion, and the lower shank remains plain for practical future resizing.

Care

Clean with lukewarm water, mild dish soap, and a soft brush, then rinse and dry thoroughly. Avoid chlorine, bleach, abrasive cleaners, and impact-prone activities. Have the corner claws and hidden-halo stones checked periodically, particularly after a hard impact.

Frequently asked questions

Is this a radiant-cut or emerald-cut ring?

This ring has a radiant-cut moissanite or lab-grown diamond center, according to your selection. The triple-claw detail describes the setting: three petite claw tips at each of the four clipped corners.

Is the wedding band included?

No. The price is for the engagement ring only. Any companion band shown is sold separately.

Is the hidden halo visible from the top?

Only minimally. The halo is positioned beneath the center stone so the ring reads as a clean elongated radiant solitaire from above and reveals the halo from the side.

Is this a low-profile radiant engagement ring?

It is a low-to-moderate cathedral design. The stone sits only as high as needed to accommodate the secure basket, hidden halo, bridge, and wedding-band clearance.

Why use triple-claw prongs?

Three petite claws at each clipped corner create a symmetrical fine-jewelry detail while securing the radiant’s four corners. All four corner clusters match.

Can a straight wedding band sit beside it?

The bridge is specifically designed to accommodate many slim straight wedding bands, allowing a flush or nearly flush stack depending on the companion band’s exact dimensions.

What quality is the moissanite?

Jewel Eternal’s colorless moissanite standard for this ring is D color and VVS1 clarity or better.

Which metal is best for long-term bridal wear?

Solid 14K gold and Platinum 950 are the preferred long-term fine-jewelry choices. Sterling silver and 14K gold over sterling silver provide lower-entry alternatives where offered.
