Why Proper Ring Sizing Matters

A ring that's too loose risks falling off and getting lost. A ring that's too tight is uncomfortable and can even restrict circulation. Our professional ring sizing ensures your ring fits perfectly — snug enough to stay secure, loose enough to slide over your knuckle comfortably.

At Diamond Gems Jewelry, we use precision tools and decades of experience to resize rings in gold, platinum, silver, and more. Most sizing jobs are completed same-day so you don't have to be without your favorite ring.

How to Measure Your Ring Size at Home

String Method

Wrap a thin piece of string or dental floss around the base of your finger. Mark where it overlaps, then measure the length in millimeters. Compare to the chart above.

Existing Ring Method

Place a ring that fits well on a ruler. Measure the inside diameter in millimeters and match it to the size chart. Best for surprise gifts.

Pro Tips

Ring Sizing Tips

  • Measure at the right time: Fingers are smallest in the morning and when cold. Measure in the afternoon for the most accurate size.
  • Account for knuckle size: If your knuckle is larger than the base of your finger, measure both and choose a size in between.
  • Width matters: Wider bands (6mm+) typically need to be half a size larger than thinner bands for a comfortable fit.
  • Temperature and swelling: Fingers swell in heat, humidity, after exercise, and during pregnancy. Account for these changes.
  • Dominant hand: Your dominant hand's fingers are slightly larger — make sure you measure the correct hand.

FAQ

Ring Sizing Questions

Most rings can be resized up or down by 2 sizes. Going beyond that depends on the ring's design, metal, and construction. Rings with continuous pavé settings or tension settings have more limitations. We'll evaluate your specific ring and give you honest advice.

Most gold, platinum, and silver rings can be resized. Tungsten carbide and ceramic rings cannot be resized due to the hardness of the material. Titanium rings can sometimes be sized down but not up. Rings with eternity-style settings can be more challenging.

Simple sizing for standard gold rings can often be done same-day — sometimes while you wait. Complex rings with intricate settings or platinum rings may take 1-3 business days. We'll give you a timeline when you bring it in.

When done by a skilled jeweler, sizing should not damage your ring. Our craftsmen carefully cut, add or remove metal, solder, and polish so the sizing point is invisible. We always inspect and clean your ring after sizing.

Ring sizing at Diamond Gems Jewelry starts at $40 for standard gold sizing. Platinum sizing starts at $60. The final price depends on the metal type, ring complexity, and how many sizes are needed. All purchased rings from our store get one free sizing.
