Moissanite Freesia 2mm Solitaire Engagement Ring - 18K Yellow Gold. Lustrous metal flows upwards like vines reaching towards the sun in this subtly nature-inspired solitaire ring that secures the center stone in classic claw prongs. The band gently tapers from 2mm to 1.2mm to complete the look with a sleek finish. As a Brilliant Pick, this piece displays the best and brightest in fashion and design and is beloved by Brilliant Earth designers and customers alike.
