8 Carat Engagement Rings

Eight carat engagement rings in solid 14K gold — the largest weight we make, in both lab grown diamond and moissanite.

The scale

An eight carat round measures around 13mm, wider than most fingers. A ring this size has more in common with a cocktail ring than with a traditional solitaire, and it behaves like one: it catches every light in a room and it is the first thing anyone notices.

Before you buy one

Be honest about how it will be worn. Eight carats sits high, it is heavy enough to rotate on a loose finger, and it will catch on knitwear, bags and hair. For daily wear, choose a bezel or half bezel and size the ring slightly closer than you would a thin band so it does not spin. For an occasion piece, a raised setting shows the stone from every angle and the snagging matters less.
