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.

A gold ring formed as a continuous double helix, diamonds invisable set along the twists. Never forget your core.

  • 4.50 grams, 14k Solid Gold
  • 0.55 carats, Natural Diamonds
  • Kimberley Certified Diamonds (Conflict Free)
  • Band Width: 5mm

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.

14k Solid Gold

All Porter Lyons pieces are cast in recycled 14k gold — sourced to reduce our impact on the earth without compromising the integrity of the metal. 14k is our chosen alloy for its durability, warmth, and the way it holds form over time.

Diamonds

All Porter Lyons diamonds are natural and earth-forged — formed over millions of years under extreme heat and pressure, and long regarded as among the most energetically concentrated stones on earth. Each diamond in our collection is GHI in color and SI1–SI2 in clarity, unless otherwise noted in the product details.
