Ring Sizing Conversion Chart

Porter Lyons offers ring sizes 3–12 (US). Use this guide to find the correct fit before ordering. For assistance selecting a size, contact us directly.

How to Find Your Size

The most accurate methods:

  • Visit a jeweler to be professionally sized with a ring mandrel.

  • Wrap a thin strip of paper snugly around the base of the finger. Mark where it overlaps, measure flat in millimeters, and match to the circumference column below.

  • If between sizes, size up — especially for wider bands (see Wide Band Sizing below).

Tip: Fingers are largest at the end of the day and in warm weather. Measure then for the most comfortable everyday fit.

The Nile Backbone Ring honors Porter Lyons' heritage with its signature alligator backbone design, symbolizing strength and resilience. This bold motif is flanked by tapered baguette diamonds, enhancing the ring's elegant symmetry while adding a modern edge.

  • 1.30 grams, 14k Solid Gold
  • 0.40 carats, Natural Diamonds
  • Kimberley Certified Diamonds (Conflict Free)

Fine jewelry is meant to be worn, and over time, 14k gold will develop a natural patina — minor surface wear that speaks to use, not diminishment. Keep your piece away from harsh chemicals, including chlorine, hairspray, and lotions, and store it in its box when not in use. To clean, use warm water with a soft-bristle brush, or our jewelry cleaner for additional shine— and note that pearls, turquoise, and Ethiopian opals should never be submerged or placed in an ultrasonic cleaner.
