Lab-Grown Oval Cut Cornflower Sapphire Leaf Engagement Ring in 14K Solid Rose Gold

This cornflower sapphire ring in rose gold pairs a genuine lab-grown cornflower-blue sapphire with the warm blush of solid 14K rose gold, framed by delicate leaf detailing. The cool periwinkle-blue stone against warm rose metal is a soft, romantic complementary contrast — a nature-inspired, fairy-tale ring with September's birthstone at its heart.

Rose gold & cornflower blue

Where white gold gives cornflower sapphire a cool, icy frame, rose gold does the opposite — its warm pink tone sets up a soft complementary contrast against the blue, making the stone feel romantic and vintage rather than crisp and modern. If you're weighing metal colors, our guide to yellow vs white vs rose gold shows how each shifts a blue stone's look. Prefer cooler? This design is also offered in white and yellow gold.

The cornflower sapphire

The center is a genuine lab-grown sapphire in the coveted cornflower blue — a soft, slightly hazy periwinkle that's historically the most prized sapphire color. Lab-grown means it's a real sapphire (corundum) created in a lab rather than mined, with vivid color at a far more accessible price, plus lab-grown sapphire accents. At 9 on the Mohs scale, sapphire is second only to diamond in hardness, so it's excellent for daily wear. It's September's birthstone — our September birthstone guide covers its meaning and lore.

The leaf design

Sculpted leaves trail along the band, framing the blue center like foliage around a still pool — an ethereal, woodland look for a non-traditional bride. There's more in our nature-inspired engagement rings.

Choose your metal

This ring is solid gold — the metal itself, not plating or vermeil over a base metal. Choose your karat from the drop-down; each is real solid gold, and the warm rose tone gives the blue sapphire a soft, romantic frame. The color is permanent: it won't wear off and won't turn your skin green.
