Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of this marquise diamond, casting a slender, luminous shadow across the hand. The 9 x 4.5 mm stone’s tapered silhouette creates a striking visual rhythm, both bold and refined.

Set in polished platinum, the solitaire ring is crafted with a delicate yet secure six-prong setting that elevates the diamond while maintaining a low profile for everyday wear. The band’s smooth comfort fit balances the dramatic shape, allowing the ring to sit naturally without catching or shifting.

Each lab-grown diamond is selected for its clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical sourcing without compromise.

This design suits those who appreciate architectural elegance paired with subtlety—ideal for slender fingers or anyone seeking a statement piece that layers effortlessly with other bands. Its streamlined silhouette is glove-friendly and comfortable for daily life.

Should you need a custom size, resizing is available to ensure a perfect fit without disrupting the ring’s clean lines.
