Light breaking into color through a lab-grown diamond

Light performance

Cut to catch light, then give it back.

Excellent cut, polish and symmetry. An ideal cut returns more of the light that enters it than most stones its size.

About this necklace

One size, one long row.

This sterling silver tennis necklace keeps it even: round lab-grown diamonds of a single matched size, each held face up in its own prong setting, linked one after another for the full length. Because every link carries a stone, the row bends smoothly into a curve at the neck with no plain sections.

  • Stones: round lab-grown diamonds, all one size
  • Total weight: 7, 10, 12, 15 or 20 ct
  • Setting: separate prong settings
  • Metal: Silvadium, a tarnish-resistant sterling silver
  • Line: single row, stones end to end

Wear it with: a second, shorter chain or a pendant for layers, or stacked with a line bracelet.
