For fit, 16 in sits close to the collarbone, 18 in is the most versatile, and 20–22 in falls lower for a statement line. Clean with warm water, mild soap and a soft brush, then store flat and separate.\u003c\/p\u003e\n\u003ch5\u003eFAQ\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes this marquise diamond necklace different from a round tennis necklace?\u003c\/strong\u003e\u003cbr\u003eThe marquise shape gives the line a longer, more directional sparkle.

Because this is a continuous diamond line, the diamond count and total carat weight increase with the length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow secure is the clasp?\u003c\/strong\u003e\u003cbr\u003eThe necklace is finished with a box clasp and figure-eight safety latch. That combination is commonly used on higher-carat tennis and riviera necklaces because it keeps the closure low-profile while adding extra security.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre lab grown diamonds real diamonds?\u003c\/strong\u003e\u003cbr\u003eYes — lab grown diamonds are real diamonds with the same chemistry, hardness and sparkle as mined diamonds. They are graded on the same 4C scale and are not simulants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this necklace good for a wedding or anniversary?\u003c\/strong\u003e\u003cbr\u003eYes — the all-diamond marquise line feels formal enough for bridal and evening wear, but the clean riviera silhouette also makes it a meaningful anniversary gift.
