165 round diamonds, each in its own four-prong basket, each basket linked independently. The drape comes from the structure.
18K white gold tennis necklace, 165 round lab diamonds in symmetrical four-prong baskets linked by articulated joints, hidden box clasp with safety lock.
Available in 14K or 18K gold, white, yellow, or rose. Chain length, total carat weight, individual stone size, and stone type can be specified before production.
Mass-market diamond necklaces often use a rigid wire backbone with stone clusters attached. A diamond tennis necklace built correctly uses no backbone at all. Each of the 165 diamonds sits in its own four-prong basket, and each basket connects to the next through an articulated joint that pivots freely. The drape against the neck is not a styling result, it is a structural one. When 165 independently linked baskets hang from the collarbone, gravity pulls each joint to the position that follows the neck’s curve. A rigid construction would hold a fixed arc regardless of the wearer’s anatomy.
The necklace works three ways: as the evening statement piece worn alone, as the foundation of a layered look with a shorter pendant positioned above it, or as the sustained-wear luxury piece for someone who wants diamonds at the collarbone daily. Within our diamond necklaces collection, this is the piece built for buyers who know the term tennis necklace specifically.
The four-prong basket lifts each diamond by its corners and leaves the crown and most of the pavilion fully exposed to light. A bezel at this stone size would wrap the girdle with a metal rim, reducing the exposed crown area by roughly 30 percent and dimming the stone’s return. A shared-prong setting would reduce metal between stones but require adjacent stones to share prong positions, which constrains the spacing and makes matched-lot grading harder. Four independent prongs per stone is the configuration that maximizes each diamond’s individual light performance while keeping the setting symmetrical across all 165 positions.
The clasp is sized to match the basket width exactly, not wider. On lesser tennis necklaces, the clasp is larger than the baskets and creates a visible interruption in the diamond line. The hidden box clasp on this design is fabricated to the same profile as the baskets, so it reads as part of the diamond sequence rather than an obvious closure. The safety lock is integrated into the clasp face rather than added as an external chain.
The necklace is solid 18K white gold throughout, including the prong baskets, the link joints, and the clasp body. 18K is denser than 14K, which gives the white gold its bright mirror-finish tone and helps the rhodium plating hold longer through repeated skin contact. The 165 stones are lab grown diamonds, graded and matched as a complete set before any stone enters a basket. In a single-stone piece, one slightly off-color stone is invisible. In a 165-stone tennis necklace worn around the neck at eye level, one stone that breaks the color consistency is immediately visible to anyone looking at the wearer. The matching happens before setting, not after.
This necklace is built to order. Chain length is the decision that changes how it drapes most, and stone size is the decision that changes how it reads at distance.
Chain length determines where the necklace sits on the body and how it drapes at that position, send that first (16, 17, or 18 inch, or measure from the base of your throat to where you want the necklace to fall). Add your preferred gold karat and color, your target stone size or total carat weight, and your diamond type (lab or natural). If you plan to layer this necklace with a pendant, mention the pendant length so the production team can advise on stone size for visual balance.
