5 Kate Middleton Engagement Ring Halo Setting

Halo engagement rings feature a circle of smaller stones in a, er, halo-style circle around the center stone of a ring. Although diamonds are often used for the halo, other precious gems like emerald, rubies or sapphires can be used too, to provide an interesting and unusual contrast effect. Although in this case the contrast is reversed!

Choosing a halo setting engagement ring is a great way to make a center stone look larger than it really is without the costs involved in actually splashing out on a larger stone.

What shape is Kate Middleton’s engagement ring?

The center stone of Kate Middleton’s engagement ring is a stunning oval cut blue sapphire. Blue sapphires are definitely the most well-known and beloved variety of sapphire due to their strikingly vibrant hue and the way they pair so brilliantly with white settings and diamonds.

A precious gemstone second in hardness only to diamond, and coupled with their symbolism of truth and commitment, sapphires have been a favorite of royals for many years.

The particular sapphire in Kate Middleton’s engagement ring is quite special, as it previously belonged to Prince William’s mother, Princess Diana, who tragically died in a car crash in August 1997.

After their mother’s untimely passing Prince Charles allowed his two royal sons William and Harry to select mementos from her possessions. Interestingly Harry, the younger brother, had chosen Princess Di’s sapphire engagement ring way back when, and William had selected a Cartier watch.

Touchingly, when William confessed his intention to propose to Kate the brothers exchanged mementos, as Harry thought of Kate like a sister and wanted her to have the ring.

When interviewed Prince William said that giving the ring to Kate was his way of making sure his mother didn’t miss out on his big day.
