The photograph shows the setting; the centre stone in it is not the weight you have picked. For that, see the picture below, which is to scale.

1 carat round

6.5 mm across

Shown actual size on a size 10½ man's hand. Carats are weight; millimetres are what the hand sees.

Raised solitaire setting

The stone lifted clear of a wide band on claws, the way an engagement ring holds one. The most presence of the three, and the most light.

We price this by hand. You get the quality options available at that shape and weight and what each one costs, usually the same day. Nothing is charged until you have seen them and said yes.
