A striking 4.00-carat sustainably grown cushion-cut blue sapphire sits at the center of this timeless design, flanked by FG/VS sustainable diamonds that add structure and brightness without overpowering the stone. Originally crafted in platinum, the Blue Nilu works beautifully as a cocktail ring, an engagement ring, or an elevated everyday piece on any finger.

This ring was first created for a client celebrating her 20th wedding anniversary. She sent me a photo of a design she loved — one priced at nearly half a million dollars — and we reimagined it with ethical stones, exceptional craftsmanship, and a sapphire that exceeded her expectations. It became one of those special projects that beautifully reenforced why I started Waltz Diamonds.
