Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow framed by two smaller stones that balance presence with quiet elegance. This three-stone semi-set invites you to select a center diamond that reflects your personal story, resting in a sleek platinum band shaped for everyday grace.

Crafted in Williamsburg, the platinum setting is polished to a satin finish that resists scratches while maintaining a subtle sheen. The low-profile design keeps the ring close to the finger, offering comfort and ease beneath gloves or alongside other bands. Each prong is meticulously aligned to secure stones without overwhelming their natural sparkle.

Our commitment to lab-grown diamonds ensures a clarity and brilliance born from innovation, paired with an ethical footprint that honors sustainability without compromise.

Ideal for those who appreciate modern minimalism with architectural clarity, this three-stone ring complements a range of hand shapes and sizes, its balanced proportions lending a confident yet understated statement.
