Lab Grown Diamond 2.14 ctw Marquise Blue Three-Stone Ring 14K White Gold

The Stone(s)

The focal point of this three-stone layout is a 1.51 carat marquise-cut lab grown diamond featuring a distinct light blue hue and VS1 clarity grade. The elongated marquise silhouette measures 11.53 x 5.95 x 3.76 mm, a ratio that maximizes surface area and displays high fire and scintillation. Flanking the primary axis are two colorless (E-F grade) pear-cut lab grown diamond side stones measuring 5.50 x 3.90 x 2.26 mm with a collective weight of 0.63 carats and eye-clean VS clarity. Every center stone carries an independent IGI jewelry certification with a laser-inscribed report number on the girdle to verify its 4Cs criteria.

The Setting

Engineered for physical balance and maximum light exposure, the center marquise lab grown diamond is held by a specialized six-prong configuration. Two heavy V-prongs encase and shield the delicate apex tips against lateral impacts, while four round side prongs anchor the girdle. The pear-cut side stones are mounted in three-prong baskets that taper downward toward the shank. This ring is built with an open wire under-gallery architecture, omitting solid metal under the baskets to allow lateral light to pass through the pavilions and maximize the optical performance of both the blue and colorless stones. The low-profile under-bezel ensures that despite the 11.53 mm length of the center stone, the ring sits flush against the finger for daily wearability without catching on fabrics.

Metals and Finish

This trilogy piece is structured in solid 14K white gold (585 purity code), polished to a high-mirror finish. The white gold is rhodium-plated to provide a bright, neutral backdrop that avoids reflecting warm tones into the blue marquise diamond, preserving its true color saturation. The plain polished shank features a slight knife-edge profile that tapers cleanly as it approaches the pear-cut side stones, creating a visual transition that emphasizes the gemstone cluster. For custom configurations, this setting can be cast in 10K gold (417) for enhanced hardness, 18K gold (750) for a higher precious metal content, or 950 platinum for a dense, hypoallergenic weight.

OPTIONAL FAQ BLOCK

Q: Is the blue color of the marquise lab grown diamond permanent?

A: Yes. The light blue color of the lab grown diamond is uniform throughout the crystal lattice, achieved during the growth process (CVD/HPHT). It will not fade, change, or degrade over time, and shares identical optical and chemical properties with mined fancy color diamonds.

Q: How do the V-prongs protect the marquise-cut stone?

A: The points of a marquise cut are its most vulnerable areas. Traditional prongs leave the tips exposed to impact. Our setting utilizes V-shaped precious metal caps that wrap completely around both tips, absorbing external contact and preventing chipping.

Q: Can I customize this ring with a larger center diamond or in rose gold?

A: Yes. During the 24-hour post-purchase confirmation process via WhatsApp, you can modify the center stone carat size or request a different backdrop, such as 18K yellow gold or 14K rose gold, which alters how the stone’s color presents.
