Two Strand Layered Mixed Shape Diamond Necklace6. 16 carats of mixed shape diamonds span two strands of 18K white gold with round brilliants running the upper strand in bezel settings, baguette cluster stations marking the lower in illusion frames. The construction gives the piece a finished, curated look without requiring anything else at the neckline. For a wedding, a milestone anniversary or the gift that arrives in a box worth keeping.
