Buttercup: halo with split shank

What this ring is made of

Oval

An elongated brilliant that tends to look larger face-up than a round of the same weight, and the length can make a finger look longer. Some ovals show a darker band across the middle, called a bow-tie, so look at the stone in person or on video.

Prongs

Small metal claws hold the stone from above. They let in the most light and show the most of the stone, and they should be checked by a jeweler every year or so.

Halo

A ring of small diamonds right around the center stone. It makes the center read larger and adds sparkle, but it also adds width and makes the head of the ring busier.

Split band

The band divides into two arms as it reaches the stone. It makes the top of the ring look wider and more intricate without making the stone itself bigger.

Pavé shoulders

Tiny diamonds set flush into the band, leaving the back of the band plain so it can still be resized.

18k yellow gold

18k yellow gold is 75% pure gold, so the color is rich and warm. It is softer than 14k, which means it scratches a little more easily and can wear at the prongs sooner.
