Ring Size Guide

Finding Your Perfect Ring Size

Choosing the right ring size ensures both comfort and security for everyday wear. At GRYKA, we want your diamond ring to fit perfectly from the very first moment.


1. Measure Your Finger

String or Paper Method:

  1. Wrap a strip of paper or string around your finger.

  2. Mark where it overlaps.

  3. Measure the length with a ruler to determine your finger circumference.

Ring Method:

  • Use a ring you already own that fits well.

  • Measure its internal diameter in millimeters.

Best Time to Measure:

  • Measure at the end of the day, when your fingers are slightly larger.

  • Avoid measuring when cold, as fingers may shrink slightly.


2. International Ring Size Conversion

Ring sizes vary slightly depending on design and style. Use the table below to find your equivalent size across different regions:

Tip: For custom designs, minor adjustments may affect the final fit slightly.


3. Tips for Accurate Sizing

  • Measure your finger 2–3 times to ensure consistency.

  • If your knuckle is larger than the base of your finger, choose a slightly bigger size.

  • When between two sizes, it’s safer to choose the larger one for comfort.


4. Free Ring Resizing Service

At GRYKA, we provide one-time free resizing within 30 days of purchase (excluding special or custom designs).

💡 Extra Tip: Keep in mind that some wide-band rings may feel tighter than slim bands. When selecting a wide ring, consider sizing 0.5–1 size larger for comfort.
