Product Description
A brilliant mix of artistry and geometry defines this Fancy Blue Round Cut Cluster Lab Diamond Engagement Ring. Each ethically crafted lab grown diamond, from the vivid Blue VS diamond (0.30 TCW, 1.50 mm) to the icy EF-VS white diamonds (0.30 TCW, 1.50 mm), is placed with careful precision. This layered arrangement forms a dimensional pave dome. This signature detail improves sparkle, symmetry, and finger coverage. The contrast between blue and white round shaped diamonds adds a captivating gradient effect that shines from every angle.
The eye-catching design features cluster, snowflake, floral burst, dome cluster, and multi stone halo styling. This makes it a standout choice for modern brides, anniversary gifts, and fine jewelry collectors. The micro prong pave setting secures each diamond while maximizing fire and brilliance. It ensures durability without losing delicacy. This cluster shape offers the glamour of a cocktail ring combined with the elegance of an engagement piece. It has also earned alternative names like blue diamond promise ring, round cluster bridal ring, and lab diamond round brilliant ring.
A sleek 2.50 mm comfort fit band, made of 925 sterling silver, 10K–18K solid gold, or 950 platinum, offers polished refinement in your choice of yellow, white, or rose metal tones. You can fully customize it in bandwidth, depth, diamond size, and metal purity. It includes an official Ouros authenticity certificate, along with optional engraving and flexible payment plans.
