Choosing the right ring size is crucial for comfort and security. Whether you’re buying a ring as a surprise or for yourself, it’s important to get the size right the first time. This guide provides detailed methods to measure your ring size accurately at home, ensuring you find the perfect fit.

Manual Measurement Using String or Paper

Step 1: Gather Your Tools

A piece of non-stretchy string or a thin strip of paper
A ruler with millimeter (mm) markings
A fine-tip marker or pen

Step 2: Measure Your Finger

Wrap the String or Paper Around Your Finger: Ensure it fits snugly but isn’t too tight.
Mark the Overlap Point: Use a marker to indicate where the string or paper overlaps.
Measure the Length: Lay the string or paper flat and use a ruler to measure the distance from the start to the marked point.

Step 3: Find Your Ring Size Using the Chart Below

Additional Tips for Accurate Sizing

Measure at the Right Time: Your fingers can change size throughout the day. Measure your finger at the end of the day when your fingers are at their largest to ensure the best fit.
Consider Knuckle Size: If your knuckle is larger than the base of your finger, you may need to size up. Measure both your knuckle and the base, then choose a size that fits comfortably over your knuckle.
Double-Check: It’s a good idea to measure multiple times to ensure accuracy.

Why Accurate Sizing Matters

Getting the correct ring size ensures that your ring is comfortable to wear and stays securely on your finger. A ring that’s too tight can be uncomfortable and difficult to remove, while a ring that’s too loose may slip off and get lost. By following these methods, you can confidently determine your ring size at home and ensure your new ring fits perfectly.

Inspired by the soft curves shaped by wind over time, the Dune Twinstone Ring captures the quiet movement that defines the Dune collection.

At its centre, a pear-shaped opal and a round diamond rest within a gentle contour of polished gold. The band rises softly around the stones, forming a natural cradle that allows them to sit closely together while maintaining a sense of balance and openness.

The opal reveals subtle flashes of colour as it catches the light, while the diamond adds a bright point of brilliance beside it. Together they create a delicate contrast, soft glow and crisp sparkle meeting within a single flowing form.

The band curves smoothly toward the stones, giving the ring a refined and organic silhouette that feels effortless on the hand. Light, elegant, and easy to wear, the design is perfect for everyday moments while still carrying a quiet sense of character.

Crafted in recycled gold, the Dune Twinstone Ring reflects the calm simplicity of the Dune collection.

Two stones.
One gentle curve.
A quiet meeting of light and colour.
