Diamond rings stand for love. They are a vital part of wedding ceremonies. Picking a right diamond matters a lot, yet the band design also carries huge weight. A ring band does not only hold the diamond in place, it also shows the wearer’s unique personality and charm. Many buyers wonder, what are the common diamond ring styles sold at Blue Nile?
Simple Prong Styles: Six-prong & Four-prong
Simple designs create timeless classics. Six-prong and four-prong diamond ring styles have existed for hundreds of years. The iconic six-prong design has a history of nearly one hundred years. It is everlasting, minimal and can stand the test of time. The most famous examples include Tiffany’s classic six-prong ring, Cartier’s iconic four-prong bullhead style, and the HW ring from Harry Winston. Blue Nile also provides a wide range of six-prong and four-prong band options, and they look really nice when worn. Two typical choices are Petite Hidden Halo Solitaire and Classic Six-Prong Solitaire.

Bands With Side Pave Diamonds
If you think a plain band looks empty and lack decorations, you can add small side diamonds. The whole ring will then shine brightly, just like many little stars surrounding a bright full moon. Blue Nile has lots of choices in this category, such as Scalloped Pavé Diamond Engagement Ring and French Pavé Diamond Engagement Ring in Platinum (1/4 ct. tw). Some customers say this style catch eyes much easier than plain single stone rings. Small diamonds along the band add soft sparkles when hands move.
