3.03 Square Sapphire & Diamond Engagement Ring 14k

This 'By Filigree' engagement ring centers a 3.03 carat square cut blue sapphire in a four-prong basket setting, flanked by two old mine cut diamonds weighing .21 carats each for a total of .42 carats.

The square cut gives the sapphire clean, geometric lines with step-cut facets that emphasize its deep blue color rather than creating sparkle. Old mine cuts have a cushion-like shape with a high crown and small table, producing broader flashes of light and a softer glow compared to modern brilliants.

Set in 14 karat yellow gold, the ring includes contour bands that wrap around the finger to follow its natural curve, creating a secure and comfortable fit. The yellow gold warms the overall look and provides strong contrast against the sapphire's oceanic blue. At just over three carats, the sapphire delivers substantial presence while the diamond accents add bright punctuation on either side.
