Platinum Engagement Rings

Refined, balanced, and beautifully detailed, sidestone engagement rings offer a timeless design that is defined by a central stone flanked by smaller stones along the band. Sidestones add a subtle shimmer and sophistication without taking focus away from the centerpiece, each enhancing the brilliance of the ring while representing the journey you’ve shared. From round and oval to emerald and marquise center stones, sidestone settings are wonderfully versatile and can be personalized with pavé diamonds, baguettes, or colored gemstones to reflect your unique story. At Cullen, each sidestone ring is handcrafted by our expert jewelers using lab-grown diamonds, moissanite, or lab-grown sapphires — a responsible, sustainable choice designed to last a lifetime.
