Rings
Find your ring size
H&Aquarius rings follow standard US sizing, with most styles available in US 5–8. Measure the inside diameter of a ring you already own, or measure the circumference of your finger to find your closest size.
Necklaces
Find your ideal length
Necklace length determines where a piece sits and how it layers with other jewelry. Measure a necklace you already own, or use a flexible measuring tape or piece of string around your neck to find where you would like your necklace to sit.
Bracelets
Find your bracelet size
Most H&Aquarius bracelets are available in 16 cm (6.3") and 17 cm (6.7"), while selected designs feature adjustable sizing. Measure your wrist circumference to find your recommended size.
Quick Size Reference
Rings
| US Size | Inner Diameter | Inner Circumference |
|---|---|---|
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.8 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 56.9 mm |
Between sizes? We recommend choosing the larger size. Wider bands may feel slightly more snug than delicate bands of the same size.
Bracelets
| Wrist Circumference | Recommended Bracelet Size | Fit |
|---|---|---|
| Up to 15 cm / 5.9" | 16 cm / 6.3" | Neat, closer fit |
| 15–16 cm / 5.9–6.3" | 17 cm / 6.7" | Comfortable fit |
| Over 16 cm / 6.3" | Check individual product sizing | Varies by design |
Between sizes? Choose the larger size if you prefer a little more movement around your wrist. Beaded, ceramic, wide, and structured bracelets may feel closer than fine chain bracelets of the same length.

Necklaces
Necklace length describes the full end-to-end length of the necklace, including the clasp. Where a necklace sits on the body can vary depending on your neck size, height, body proportions, and pendant size and design. For the most accurate placement, refer to the chain length listed in the Details & Dimensions section of each product page.
How to Measure
Rings
Measure the inside diameter of a ring you already own, or measure the circumference of your finger. Measure the exact finger you plan to wear the ring on.
Necklaces
Lay a necklace you already own flat and measure it from end to end, including the clasp. Alternatively, place a flexible measuring tape or piece of string around your neck where you would like the necklace to sit.
Bracelets
Wrap a soft measuring tape around your wrist, just below the wrist bone. Keep the tape comfortably snug against your skin without pulling it tight. The measurement you get is your wrist circumference—not your bracelet length.
A Note on Fit
Jewelry of the same listed size can feel slightly different depending on its design and construction.
Rings
Wider bands may feel more snug than slim or delicate bands.
Necklaces
Placement varies depending on neck size, height, body proportions, and pendant design.
Bracelets
Beaded, ceramic, wide, and structured bracelets take up more internal space and may feel closer than fine chain or tennis bracelets of the same length.
