Complete Description
A continuous line of round lab-grown diamonds in a 3-prong straight-line setting. Available in 14k yellow, white, or rose gold, and in nine carat weights from 5ct to 60ct — starting at $2,800 for the 5ct and running to $31,980 for the 60ct.
Every stone is DEF color and VS clarity with an excellent cut grade, matched across the strand for consistent saturation and return of light. A 5ct strand reads as quiet daily brilliance; a 30ct+ strand is a statement piece.
3-prong vs. 4-prong
Both settings secure the same diamonds; the choice is about how the stones sit and how much metal shows. A 3-prong lifts each diamond slightly higher and leaves more stone exposed — the effect is a brighter read from an arm's-length view, with less metal visible in the line. A 4-prong holds each stone with one more point of contact, which some buyers prefer for everyday wear and for larger carat weights. Neither is more secure in ordinary use; both are industry-standard for tennis settings.

How it wears
The 16-inch length sits at the collarbone, visible with open necklines and layerable with longer pendants or stations. Metal choice shifts the read: white gold disappears into the stones for maximum brilliance; yellow gold warms them; rose gold softens the tone.
