A Guide to Engagement Ring Styles

The "Big Question" is looming large. But first - the ring.

Because there's a lot of nuptial bling out there to sift through, Costco.com is here to help you find the engagement ring style that's just right for you.

1. Traditional

A timeless shape that will always be in style, the round cut engagement ring is a classic bride's dream.

Pro-Tip: Going for a classic look? Wedding sets are a traditional style that feature an engagement ring and matching wedding band.

2. Glamorous

Another favorite among brides, the princess cut has a square or rectangular shape that offers a distinct alternative to its more perennial counterpart — the round cut — without sacrificing any light return.

Pro-Tip: To make a modest stone appear larger and more luminous, surround it with smaller support diamonds to create a halo effect.

3. Sophisticated

The emerald cut, with its cropped corners and step-like dimensions, is not as brilliant as the round cut, but long lines and a "hall of mirrors" effect offer even more dramatic flashes of light.

Pro-Tip: A diamond does not need to be flawless. Brilliant cut diamonds with slight inclusions are still stunning, and any imperfections would require magnification.

4. Unique

A cross between a rectangle and an oval, the cushion is known for its pillow-like shape. Rounded corners deliver a more antique look.

Pro-Tip: Yes, summer is wedding season, but it's also one of the best times to shop for an engagement ring.

5. Nontraditional

For the "avant-garde" bride, colored gemstones and diamonds are a modern and refreshing alternative to their more orthodox cousin, the translucent diamond.

Pro-Tip: A diamond band engagement ring is another way to spice things up. Plus, it rests comfortably next to a solid metal wedding band after the long-awaited "I do."
