3mm Moissanite Tennis Necklace | Single-Row Round-Cut 925 Silver Chain

A 3mm round-cut moissanite tennis necklace gives you a continuous line of fire that reads like fine jewelry but wears every day. The single row of prong-set stones sits flat against the collarbone, each gem cradled in its own four-prong box link so light enters from every facet rather than being blocked by bezels. Every stone is DEF colorless, VVS clarity moissanite cut to a 3mm round (about 0.10ct DEW each), with a refractive index of 2.65 against a mined diamond's 2.42 — that higher index is the measurable reason the chain throws more rainbow flash under store lighting. At 9.25 on the Mohs scale the stones resist the scratches that dull cubic-zirconia copies within months. The chain is 925 sterling silver finished in a bright white rhodium-look polish, set on a flexible link that drapes evenly with no kinks, and secured by an integrated box clasp with a fold-over safety catch. Styling take: a 3mm width is the daily-wear sweet spot — substantial enough to catch light across a room, slim enough to layer under a 5mm piece or a pendant without competition. Choose 16in to sit high at the throat, or 20-22in to fall toward the neckline of an open collar. It photographs as one clean, unbroken line of light, which is why it works equally well over a crisp buttoned shirt or against bare skin in a slip dress. Specs: 3mm round moissanite (~0.10ct DEW each), DEF / VVS, RI 2.65, 9.25 Mohs; 925 sterling silver, rhodium-finish; box clasp; 16/18/20/22in.
