Keel

$1,100.00

A fancy green hexagon-cut lab diamond — its proportions kite-shaped and deliberately elongated — rising on a pointed contour, with a single small round diamond set at the peak. The shank climbs to meet the stone rather than carrying it; the result is an architecturally tall piece that sits 10.9 millimeters off the finger. Keel is the line that gives a boat its direction, and the word felt right for the only silhouette in the collection with a deliberate edge.

  • A note on 10k: 10-karat gold is the strongest everyday gold alloy — more scratch- and dent-resistant than 14k or 18k, with a warmer, quieter tone. We chose it deliberately, for jewelry that's meant to be worn, not stored.

Care

10-karat gold is durable enough for daily wear, including water exposure. For longevity, we recommend removing the ring during high-impact activity (weight training, rock climbing, manual labor) and avoiding direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. A soft-bristled brush and mild soap in warm water is sufficient for home cleaning. Note: Keel's architectural profile makes it slightly more vulnerable to catching on fabric; we recommend extra care around knitwear. We offer complimentary lifetime polishing and inspection on every piece.
