Deco Round-Cut Three-Stone Engagement Ring with Tapered Baguette Side Stones

Clean, refined, and beautifully architectural—this three-stone engagement ring features a brilliant 3 ct round center diamond framed by two tapered baguette side stones. The round brilliant cut brings exceptional sparkle, while the baguettes introduce sleek, linear geometry for a timeless Art Deco balance. The polished, slender band keeps the focus on the stones, allowing the contrast between the round and step-cut facets to shine.

Important Note on Final Size

Because this design offers multiple center-stone sizes (3 - 5 ct) and US ring sizes 4–9, the exact measurements will adjust proportionally to maintain balanced proportions and a seamless design. Larger stones will be paired with proportionally longer tapered baguettes, and the basket height will adjust slightly to support the center stone securely. Every ring is crafted to ensure the three-stone layout remains harmonious, regardless of the size chosen.
