Buying guide

Side stone shapes and what they do

  • Three stone: one side stone on each side of the center, often round, pear or trillion. This is the most common look in the collection.
  • Marquise side stones repeat the center's shape for a longer, slimmer line.
  • Baguettes are straight step cuts that give a clean, geometric frame, often channel set.
  • Pear side stones point toward the center and widen the ring's outline.

Band styles

Many marquise rings with side stones add a pavé band, so lab-grown diamond accents continue below the sides. Channel set bands hold stones between two metal walls for a smooth edge. Some settings use a split shank or bypass band, and a few have vintage milgrain, filigree or floral shoulders, or a hidden halo under the center.

Center, metal and price

Most settings can hold a fancy blue, yellow, pink or green center, and many are made for a black center. Gold comes in 10K, 14K or 18K. Most bands are about 1.8 to 2.5 mm wide. Prices are for the setting only, from under $250 and mostly between about $850 and $1,350; the center is priced when you choose it.
