1.55 CTW Lab Grown Diamond Heart Hidden Halo Solitaire Ring 14K Yellow Gold

The Stone(s)

The architectural centerpiece is a 1.50ct heart shape lab grown diamond, selected for its highly balanced cleft, distinct lobes, and symmetrical silhouette. Graded as F color (colorless) and VS1 clarity, the stone is entirely eye-clean, maximizing internal facet reflection density while avoiding visible structural inclusions. Beneath the main stone’s girdle, a secondary group of eight round brilliant lab grown diamonds (0.05 CTW, EF color, VS clarity) forms a concealed horizontal collar. This hidden gallery layout captures and reflects light from beneath the pavilion, altering the diamond’s standard dispersion patterns without adding bulk to the primary profile. Every center diamond is independently graded with a laser-inscribed report number on the girdle, verifiable directly at igi.org.

The Setting

The heart silhouette is secured by a specialized 4-prong mechanical setting. Each claw prong is positioned at a key anatomical point—protecting the vulnerable lower point and the curved upper lobes—to anchor the stone’s perimeter against daily impact. The setting features an exposed pavilion architecture, allowing the stone to sit low and flush against the finger profile. This low-profile clearance prevents snagging while leaving the diamond’s lower facets accessible to light transmission. The micro-pavé gallery wire collar is integrated directly into the prong base, ensuring structural stability without sacrificing the ring’s minimalist layout.

Metals and Finish

This piece is built by default in 14K Gold (585) yellow, which provides an optimal, durable balance of pure gold content and structural alloy hardness for daily wear. The band is a 2.0mm solid round-wire shank finished to a high polish, designed to taper slightly as it joins the head setting. The interior band profile is softly radiused for active comfort. The setting is also available across four alternative metal tiers to match specific lifestyle needs: 18K Gold (750) for a richer gold hue, 10K Gold (417) for maximum scratch resistance, and 950 Platinum—a dense, hypoallergenic alloy that provides the ultimate prong security for high-carat settings.

Customisation and Origin

Every ring is built to order and can be tailored to your precise metrics. Standard customization paths accommodate center stone carat weights from 0.25ct up to 3.00ct+, along with adjustments to metal tone (yellow, white, or rose), band width, and specific international ring sizes (including quarter and half-size steps).
