Product Information
The Chi-Rho - the first two letters of “Christos” in Greek - is the oldest monogram of Christ, used since the Roman Empire. Here it rises in bold silver relief from a black onyx inlay, set into a cross-shaped face that frames the symbol with the very sign of salvation. Inside: Alpha and Omega. A small Chi-Rho medallion is engraved on the shank. Handcrafted in Jerusalem for a man who carries the ancient faith.
“I am the Alpha and the Omega, the First and the Last, the Beginning and the End.” - Revelation 22:13

Size Chart
Finding your perfect fit shouldn't be a guessing game. Whether you're choosing a ring for yourself or picking one as a gift, here's everything you need to get the size right the first time.
How to Find Your Ring Size
Option 1: Measure a ring you already own
Take a ring that fits the intended finger well and measure the inside diameter in millimeters. Match that number to the chart below.
Option 2: The string or paper strip method
Wrap a thin strip of paper or string snugly around the base of the finger where the ring will sit. Mark where it overlaps, then measure the length with a ruler in millimeters. Match that number to the circumference column below.
Option 3: Not sure, or buying as a gift?
The average US ring size is 7 for women and 10 for men. If you're buying a surprise gift and can't get an exact measurement, this is a safe place to start — and if it needs adjusting later, resizing is simple.
A few tips for an accurate measurement
- Measure in the evening, when fingers are at their largest
- Avoid measuring right after being out in the cold, or after a workout — fingers shrink in cold weather and swell in heat
- If you're between two sizes, size up rather than down
- Wider bands fit more snugly than thin ones, so consider going up half a size for a wide band
