14K Yellow Gold Synthetic Sapphire and Old European-Cut Diamond Three-Across Ring

This 14K yellow gold antique three‑across synthetic sapphire and diamond ring highlights both refined design and period character. Centrally set within the band is a 0.48 carat cushion cut synthetic sapphire, bezel‑set flush into the yellow gold for a sleek, seamless profile. On either side of the centre stone sits an old European cut diamond, also bezel set, each rising slightly above the bezel due to the distinctive proportions and higher crown of these early diamond cuts, a hallmark of jewellery crafted in the early 20th century. 

The band itself is a classic high polish 14K gold that sits close and comfortable against the finger, tapering gently as it wraps the hand. The overall feel is balanced and elegant, with each stone proportioned to create a cohesive and timeless look. Inside the shank, the ring is hallmarked with two walking lions flanking the manufacturer’s mark "S.L&Co." This piece is a beautiful example of antique design that integrates quality materials, craftsmanship, and historical details, from the synthetic sapphire centre to the distinctive old cut diamonds and unique hallmark inside the band.

First developed in the late 19th century through flame-fusion techniques, synthetic corundum quickly gained popularity for its exceptional clarity, durability, and vibrant, consistent colour. Importantly, these stones were not seen as imitations, but rather as innovative, high-quality materials that allowed jewellers greater creative freedom, especially in the geometric and highly stylized designs of the Art Deco era. 

Old European cut diamonds, popular from the late 19th century into the early decades of the 20th, are valued for their handcrafted faceting and warm, romantic sparkle under candlelit or softer ambient lighting, contrasting with the sharper brilliance of modern cuts. The use of bezel settings for both the sapphire and diamonds also reflects a vintage sensibility, offering protection to the stones while contributing to the ring’s enduring style.
