Method 1: Measure an Existing Ring (Most Accurate)

If you already own a ring that fits your chosen finger perfectly:

• 1. Place the ring on a flat surface.
• 2. Use a metric ruler to measure the inside diameter straight across the center of the band.
• 3. Note: Measure only the empty inner space—do not include the metal walls.
• 4. Match your millimeters (mm) to the Inside Diameter column in our chart above.

Method 2: The Paper Strip Test

If you don't have a ring for reference:

• 1. Cut a thin strip of paper (about 10 cm long).
• 2. Wrap the paper snugly around the base of your finger. Make sure it can slide comfortably over your knuckle.
• 3. Mark the exact point where the paper overlaps with a pen.
• 4. Lay the strip flat against a ruler and measure the length to your mark in millimeters (mm) to find your Inside Circumference.
• 5. Match this number to our chart to find your ideal Etérea size.

Etérea rings are available in three standard, versatile sizes: 6, 7, and 8 (some models).

• Size 6. Diameter 16.5 mm. Circumference 51.8 mm
• Size 7. Diameter 17.3 mm. Circumference 54.4 mm
• Size 8. Diameter 18.2 mm. Circumference 57.2 mm

Tip: If you are between sizes, we recommend ordering the larger size. This accommodates natural finger swelling throughout the day or during warmer weather.

Yes! The pieces specifically marked as water-resistant are crafted with 18k Gold PVD plating over 316L stainless steel. This advanced plating method makes them highly resistant to water, sweat, and perfume, so you can wear them every day without worrying about tarnishing.

We use two types of premium stainless steel, and each has slightly different care needs to keep your pieces looking their best:

Waterproof Pieces (316L Stainless Steel):
These are designed for non-stop wear. You can shower, swim, and sweat in them without worrying about fading. We simply recommend rinsing them with fresh water and drying them with a soft cloth after exposure to saltwater or chlorine.

Everyday Essentials (304 Stainless Steel):
To preserve their radiant 18k gold finish, please remove these pieces before showering, exercising, or swimming. Avoid direct contact with perfumes, lotions, and harsh chemicals. When not wearing them, store your pieces in their original Etérea pouch.
