WHY CHOOSE HEART ENGAGEMENT RINGS?

Heart shaped engagement rings have a brilliant-cut centre stone shaped as a heart, with a cleft at the top and a point at the base. If you are looking at heart styles you probably want a romantic, openly symbolic ring with a shape that few others wear.

HOW TO CHOOSE A HEART ENGAGEMENT RING

Choosing a heart shaped engagement ring means checking the symmetry of the shape and protecting the point.

  • Check the symmetry: The two halves should mirror each other and the cleft should be clean and even, because the shape shows any imbalance clearly.
  • Mind the size: A heart shape reads best from around half a carat upward, where the outline is easy to see.
  • Protect the point: Look for a setting that covers the point at the base for daily wear.
  • Explore the centre stone: To compare diamond shapes more broadly before you decide, read the diamond education guides, then use this page to compare rings.
