Riviera (French for “river”) is the purest form of diamond necklace — a graduated line of stones that drapes the collarbone with no pendant or design elements interrupting the flow. The form requires precise matching across every stone in the line, since any variation in color, clarity, or proportion is visible against the wearer’s skin.

Every necklace in this collection consists of GIA-certified natural diamonds in matched parcels — round brilliant, pear shape, emerald cut, or mixed shape — graduating from a center carat weight outward to the clasp. Color grades span D-G across the white pieces; clarity sits between Flawless and VS2. Total carat weights run from approximately 20cttw to over 100cttw.

Settings are hand-fabricated in platinum with individual baskets per stone and articulated underlinks that allow the piece to lie flat against the décolletage. Hidden box clasps with figure-eight safety mechanisms are standard. Each riviera takes weeks to assemble — the matching alone often spans months across multiple cutting houses.
