Design & Production Notes

Precision-manufactured drop earrings developed for fine-jewelry retailers, wholesalers, independent designers, and private-label brands. This articulated two-stone design combines a kite-set princess-cut diamond with an elongated marquise-cut drop, creating a distinctive silhouette suitable for bridal, occasion, and contemporary fine-jewelry collections.

Princess-Cut and Marquise-Cut Design

The upper section features a calibrated princess-cut lab-grown diamond positioned in a kite orientation and secured with a four-prong setting. An elongated marquise-cut diamond is suspended beneath it through a compact articulated connection.

The flexible connection allows the lower diamond to move naturally with the wearer. This movement creates changing reflections from different viewing angles while maintaining a refined and lightweight appearance.

Stone dimensions, proportions, setting structure, drop length, metal specifications, and movement can be adjusted according to the buyer’s design requirements and target market.

Advantages for Buyers

Articulated Drop Construction

The concealed connection allows the marquise-cut diamond to move independently while keeping the overall design visually clean. Link movement, alignment, spacing, and durability are reviewed during sample development and production inspection.

Flexible OEM and ODM Development

The displayed princess-and-marquise combination can be used as a starting point for custom development. Alternative stone shapes—including emerald, pear, oval, radiant, round, and cushion cuts—can be evaluated according to the required design.

Scalable Manufacturing

Production supports one-piece samples, boutique private-label collections, customized retail orders, and repeat wholesale programs. Final pricing and production capacity depend on the approved materials, stone specifications, setting complexity, and order quantity.

Material and Documentation Options

CVD and HPHT lab-grown diamonds are available in different carat weights, dimensions, color grades, and clarity grades. Independent grading documentation can be arranged for qualified stones when specified before production.

Solid gold and PT950 platinum options are available. Nickel-free or market-specific alloy requirements should be confirmed in the approved order specification.
