Description
A deep blue cushion London Blue Topaz anchors this vintage necklace in sterling silver, joined by small round natural diamonds. The sterling silver carries an antiqued finish that darkens the recesses and gives the surface depth, with yellow gold accents adding a warm contrast. The pendant hangs from the chain on a bail, and the chain closes with a lobster clasp that won't open on its own. You can wear it over a white shirt or with a knit in cool gray. It is a considered choice for a December birthday or an anniversary. Quietly old-world.

What is a cushion cut necklace?
It has a softly squared stone with rounded corners. The shape sits between a square and an oval, so it looks soft but still has clean edges. Many styles here use a bezel setting, where a smooth metal rim wraps the stone for a modern look.
Which cushion necklace is best for everyday wear?
A bezel-set style is a smart pick for daily wear. The metal rim surrounds the stone, so the edges are less likely to catch on clothing. Amethyst and blue topaz in sterling silver are simple, easy choices to wear and layer.
Which cushion necklace styles are most popular?
Lab-grown diamond and amethyst styles lead the list. Cushion lab-grown diamond necklaces in 14K white gold appear near the top, followed by amethyst, garnet and diamond pieces in sterling silver. Blue topaz, peridot and green quartz styles also rank well.
How do I care for a cushion necklace?
Wipe it with a soft cloth after wearing. Store it separately in a pouch so the stone and metal stay free of scratches, and keep it away from perfume and harsh cleaners. See our jewelry care guide for more tips.
