A round brilliant sits at the center, framed by marquise and baguette diamonds that taper toward the band. The different cuts catch light in their own way, so the ring changes character as your hand moves instead of flashing in a single pattern.
The marquise diamonds soften the outline beside the center stone, while the baguettes add crisp, straight reflections. Small round accents bring the arrangement together and keep the transition into the band balanced from every angle.
Choose your preferred center diamond from 1 to 4.5 carats, then select your metal. Every ring is made to order by Signora Jewels, with the setting proportioned for the diamond you choose.
