Buying guide
Choosing a round moissanite engagement ring
A round centre stone gives a ring an even outline from every direction. In a round moissanite engagement ring, that symmetry can be the focus of a simple setting or the starting point for a more detailed composition. Look at the relationship between the stone's diameter, the claws and the band rather than considering any element in isolation.
Start with diameter, not the size label
Moissanite is a different gemstone from diamond. Where a size is expressed as a diamond-equivalent weight, it is a comparison, not the moissanite's actual weight. The millimetre measurements provide a more direct way to judge how much of your finger the centre stone will cover. A wider band also changes the visual balance around the same diameter.
Decide how much detail surrounds the centre
Our moissanite solitaire rings provide a useful starting point for an open, uncomplicated setting. Compare the wider shoulder set collection when you prefer detail along the band. Check the specification of any accent stones separately from the moissanite centre.
Compare a round outline with an oval
A round stone has an even diameter, whereas an oval moissanite ring introduces length along the finger. Neither outline is inherently more flattering: the preferred proportions depend on the hand, the band and the presence you want from the finished ring.
What should I check before choosing?
Review the centre-stone measurements, setting height and space available for a wedding band. Moissanite's flashes of coloured light give it a character of its own; it should not be assessed as though it were a natural diamond. Our moissanite guide explains the material, and a ring consultation can help you compare proportions and settings.
