Oval Sapphire & Trillion Diamond Ring in 18K Yellow and White Gold Signed ER

This classic three-stone ring features a richly saturated oval sapphire—deep navy with flashes of midnight—set in a two-tone 18K gold design. On either side, brilliant trillion-cut diamonds add light and symmetry, drawing the eye toward the sapphire’s vivid center.

The sapphire is currently untested and may be either a natural, heat-treated sapphire or a lab-created stone. Its deep, even color and clarity are consistent with both. We are listing this piece transparently and without passing on certification costs, but third-party gemological testing is available upon request.

Please note: Colors may vary slightly depending on your screen or device settings.

The timeless three-stone silhouette meets bold, regal color in this elegant ring. The sapphire’s depth is beautifully enhanced by the crisp geometry of the diamonds, creating a look that’s striking yet forever wearable.
