Lab Grown Diamond Yellow Pear Three Stone 18K Gold Ring 1.72 CTW | Primira Luxury

The Stone(s)

The focal point of this three-stone layout is a 1.61 carat pear-cut lab grown diamond graded as an eye-clean SI1 with intense yellow color saturation. The distinct teardrop silhouette features a modified brilliant faceting pattern that optimizes internal light reflection, minimizing the bow-tie effect typical of fancy cuts. Flanking the central stone are two precisely matched pear-cut side stones totaling 0.11 carats, graded EF color and VS clarity. These colorless accents point outward along the band, creating a sharp structural contrast that amplifies the warm hue of the center diamond. Every stone group is independently verified under strict lab standards, with independent IGI jewelry certification available upon request to verify the graded cut, color, clarity, and carat metrics.

The Setting

Engineered for physical protection and maximum light entry, the center yellow diamond is anchored by a specialized 6-prong claw configuration. A dedicated V-prong guards the vulnerable pointed tip of the pear shape, while five low-profile claws wrap around the rounded base and upper girdle to secure the stone against daily impact. The flanking side stones are anchored in matching 3-prong micro-settings. The structural foundation features an open double-rail gallery wire basket undercarriage. This deliberate elevation lifts the pavilion facets off the finger line, allowing unobstructed light to enter from beneath and maximize the internal fire of both the fancy-yellow and colorless diamond groups.

Metals and Finish

This piece is composed of solid 18K Gold (750 purity code), selected for its traditional rich hue and the structural integrity required to balance a multi-stone setting. Following advanced color-backdrop logic, the golden prongs seamlessly blend into the yellow diamond’s perimeter to naturally saturate its warm hue, while the white metal accents beneath the side stones maintain their crisp, colorless profile. The band transitions into a high-polish, tapered split shank that narrows as it approaches the gallery to emphasize the stone architecture. For alternative lifestyle needs, this design can be rendered across our full metal matrix: 10K Gold (417) for maximum scratch resistance, 14K Gold (585) for an optimal balance of gold content and durability, or 950 Platinum for an ultra-dense, hypoallergenic setting.

FAQ

Q: Why is a 6-prong setting used for the center pear diamond instead of a standard 4-prong?

A: Pear-cut stones feature a vulnerable pointed apex that is prone to chipping if left exposed. Our architecture utilizes a dedicated V-prong to fully encase that tip, combined with five additional claws around the belly and wings. This layout ensures the stone remains balanced and locked into the gallery basket during active daily wear.

Q: Can I change the metal tone of the prongs independently from the band?

A: Yes. During your 24-hour post-purchase WhatsApp consultation, you can request a two-tone finish. We highly recommend keeping yellow gold prongs on the center stone to enrich the yellow diamond’s saturation, paired with white gold or platinum prongs for the side stones to keep them looking colorless.

Q: How is the yellow color in the lab grown diamond achieved, and will it fade?

A: The coloration is achieved by introducing trace amounts of nitrogen into the vacuum growth chamber during the CVD or HPHT process, mimicking the exact geological environment of natural fancy diamonds. Because it is part of the stone’s physical crystal lattice, the intense yellow hue is permanent and will never fade, alter, or cloud over time.
