18.60 CTW Marquise Diamond Tennis Necklace in 14K & 18K Gold

Elegant, dramatic and endlessly refined, this 18.60 CTW marquise diamond tennis necklace is designed as a continuous line of elongated brilliance around the neckline. The necklace features 124 marquise-cut diamonds, creating a graceful leaf-like rhythm that gives the piece exceptional movement and a sophisticated high-jewellery presence.

Each marquise diamond measures approximately 5.50 × 3.00 mm and weighs about 0.15 carat, producing an impressive combined diamond weight of 18.60 CTW. The stones are secured in individual collet settings, allowing the pointed marquise silhouettes to remain clearly defined while maintaining a polished, structured finish. The consistent stone size creates a beautifully balanced necklace with uninterrupted sparkle from end to end.

The articulated construction is designed to follow the natural contour of the neckline, helping the necklace sit comfortably while preserving its refined, fluid appearance. Its timeless single-row composition makes it equally suited to bridal jewellery, black-tie styling, milestone celebrations and collector-worthy luxury wardrobes.

This design is available in 14K and 18K gold, with White Gold, Yellow Gold and Rose Gold options. According to the CAD, the approximate metal weight is 34.2295 grams in 14K gold and 40.27 grams in 18K gold. Final finished weight may vary slightly after casting, stone setting, polishing and any requested necklace-length adjustment.

Diamond origin, diamond quality, certification, necklace length, closure specification and final finish are available on request and will be confirmed before production.

Created for moments that call for unmistakable brilliance, this marquise diamond necklace is an exceptional choice for weddings, anniversaries, luxury gifting and milestone celebrations.
