Frequently Asked Questions
Yes—both the marquise center and the tapered baguette sides are lab-grown diamonds matched for color and clarity to ensure a seamless three-stone look.
The marquise’s elongated outline creates a larger face-up look while staying comfortable and lightweight; the secure prong design helps protect the pointed tips.
White gold emphasizes a sleek, modern frame; yellow gold adds classic warmth and contrast; rose gold creates a soft, romantic glow around the stones.
Most three-stone rings can be resized within a small range. Share your target size (and whether you’ll stack bands) so we can confirm feasibility before purchase.
Slim pavé, plain knife-edge, or gentle curved/chevron bands complement the marquise tip and sit neatly beside the baguettes without crowding the silhouette.
