Ring Size Guide

At Colombian's Best - Emerald Company , each piece is a masterpiece of fine jewelry. To ensure a perfect and sublime fit, we have designed this exclusive sizing guide for our digital showroom.

Method 1: Measure the internal diameter of an existing ring

This is the most accurate method if you already own a ring that fits perfectly on the desired finger:

  1. Take a ring that fits you comfortably and place it on a flat surface.
  2. Using a millimeter ruler, measure the internal straight-line distance from end to end (excluding the thickness of the metal).
  3. Compare the measurement in millimeters with our correspondence table below.
Method 2: Measure the circumference of the finger

If you do not have a reference ring, follow these steps very carefully:

  1. Wrap a flexible measuring tape or a thin strip of paper around the base of your finger.
  2. Make sure the paper fits comfortably over the knuckle, as the ring will need to pass through there.
  3. Mark the exact point where the end crosses and measure the length with a ruler (this is the circumference in mm).
  4. Refer to the "Circumference" column in our technical table.
