The Rosalee is a princess-cut lab-grown diamond engagement ring in 950 platinum, centred on a clean four-prong solitaire setting. The square princess-cut centre stone remains the sole focal point, giving the design a precise geometric appearance without halo or shoulder-set detailing.

A 2mm band gives this platinum lab-grown diamond ring a balanced proportion and keeps the solitaire profile refined around the centre diamond. The four-prong arrangement defines the corners of the princess cut while maintaining a straightforward single-stone composition.

For those comparing princess-cut lab-grown diamond solitaire engagement rings, the Rosalee combines a four-prong setting, 950 platinum and a 2mm band. Its documented wedding-ring-friendly construction is designed to sit alongside most standard wedding bands.
