Three square charms hang side by side, each framing a round HPHT lab-grown diamond. Their graduated proportions give this gold-plated 925 sterling silver necklace a small, architectural rhythm across the neckline.

Includes a GRA certificate. Backed by a 2-year warranty.

The contrast between round stones and square mounts is what sets the design apart from a single solitaire. Separate bails leave a little space between the charms, making the outline easy to appreciate against a plain blouse or an open collar.

Choose it for a partner who prefers structured jewelry to floral or ornate designs. It brings a considered accent to a dinner outfit and makes a thoughtful anniversary or birthday gift without relying on an oversized pendant.

Round cut gemstone looks prettier in person

It arrived safely packed, and the round gemstone looked bright as soon as I opened the box. The S925 sterling silver gives the necklace a clean finish, while the bezel setting details add a nice amount of detail without making it feel too busy. It arrived ready to wear, with no loose-looking details. The metal and stone look well matched.

Beautiful round cut Gemstone sparkle

I've worn this necklace several times now and the stone still has a lovely sparkle. The round cut catches the light nicely, and the polished finish has stayed neat with normal care. It has kept a fresh look with gentle cleaning so far. The overall shape reads clearly when worn.

A lovely clean and simple Gemstone necklace

The round gemstone is the part that stands out most. It has a beautiful color in person, and the clean and simple design works really well with the S925 sterling silver. It feels special but still easy to style. The shine has held up nicely through normal wear so far. The packaging protected the finish well.

The Round cut really stands out

The color and cut are what make this necklace stand out. The round gemstone looks lively under different lighting, and the clean and simple design has a little more presence than a very simple piece. The small details are easier to notice in person. The piece has a nice sense of depth in person.

A bright necklace with plenty of character

This is a pretty necklace with a clear gemstone focus. The bezel setting gives it a finished look, and it has stayed bright through normal wear so far. It looks bright in photos and even livelier in natural light. The stone remains the clear focal point.
