WHY CHOOSE ROUND ENGAGEMENT RINGS?

Round brilliant engagement rings are the most popular choice of all. The round brilliant is cut for maximum sparkle and is the easiest shape to compare from one stone to the next, so if you are looking at round styles you probably want a bright, classic centre stone that will still feel right in decades to come.

HOW TO CHOOSE A ROUND ENGAGEMENT RING

Choosing a round engagement ring means putting cut quality first, then settling the setting and stone type.

  • Start with cut quality: Cut does the most visible work in a round brilliant, so compare the cut grade and proportions before chasing a higher colour or clarity grade.
  • Pick the setting: A solitaire shows the stone cleanly, while a halo adds visual size and extra sparkle.
  • Choose the stone type: Round works equally well as a lab grown diamond or moissanite, so the decision is look and budget.
  • Read the background first: For how cut quality, colour and clarity affect a round stone, read the round diamond guide, then use this page to compare rings.
