Lab Grown Diamond Cushion Rose Vintage Solitaire Ring 1.64 CTW

The Stones

The focal point of this design is a 1.48-carat Cushion Rose cut lab grown diamond. Unlike modern brilliant cuts, the antique rose cut features a flat base and a faceted dome crown, producing broad, subtle light reflections rather than intense scintillation. This center stone is independently graded by the International Gemological Institute (IGI) as G color (near-colorless) and VS2 clarity, ensuring an entirely eye-clean presentation with no inclusions visible to the naked eye. Embedded along the shoulders are 10 round brilliant accent stones totaling 0.16 carats. These accents feature an EF color grade and VS clarity profile, offering a sharp, bright contrast that frames the vintage geometry of the center diamond.

The Setting

Engineering an antique rose cut requires specific gallery structural adaptations due to the stone’s flat-bottomed architecture. This setting uses an elevated cathedral gallery with an under-bezel rail that supports the flat base while keeping the stone elevated to capture ambient light. The cushion silhouette is anchored by an eight-prong double-claw arrangement, where four pairs of low-profile prongs grip the stone’s corners. This architecture distributes retention force evenly across the girdle, protecting the stone from impacts while maintaining an open gallery profile. The accent stones are integrated using a shared-prong pavé setting along a slim round-wire shank, minimizing visible metal between the diamonds to form an uninterrupted line of light.

Metals and Finish

This piece is manufactured to order in four gold purity tiers and 950 Platinum. The default 14K gold (585) composition provides an optimal balance of gold content and structural hardness for daily wear. For higher purity, 18K gold (750) offers a richer, deep yellow gold hue, while 10K gold (417) delivers maximum scratch resistance for highly active lifestyles. The premium tier utilizes 950 Platinum (95% pure platinum), providing a dense, hypoallergenic foundation that never tarnishes and offers ultimate prong retention for the high-carat center stone. The standard finish is a reflective high polish, though alternative surface finishes—including satin, brushed, matte, or hammered—can be specified during the post-purchase consultation.

OPTIONAL FAQ BLOCK

Q: Why does this cushion rose cut diamond look different from modern cushion cuts?

The rose cut is a historical faceting style dating back to the 1500s. While modern cushion brilliant diamonds have a deep pavilion (bottom half) to reflect light upward as small sparkles, a rose cut has a flat bottom and a domed top covered in triangular facets. This creates a distinct, transparent look with broader, slower flashes of light, emphasizing the physical clarity of the diamond.

Q: How does the flat base of the rose cut affect the ring’s wearability?

Because the diamond has no pavilion, it can be set much lower to the finger than a modern brilliant cut. The low-profile under-bezel rail keeps the center stone from catching on fabrics or bumping into surfaces, making it an ideal configuration for comfortable, unobstructed daily wear.

Q: Can I request this setting with a different center stone shape or carat weight?

Yes. During the 24-hour post-purchase specification window, our Surat engineering team can adapt the CAD architecture for center stones ranging from 0.25 carats up to 10 carats. You can also swap the cushion rose cut for custom silhouette outlines or standard brilliant shapes.
