Theía de la Tierra jewelry is designed to fit naturally and comfortably, becoming an effortless part of everyday wear.
To ensure the best fit, we recommend taking a moment to measure carefully.
How to Measure Your Wrist
Wrap a soft measuring tape around your wrist, close to the skin but without tightening.
If you do not have a measuring tape, use a thin string or strip of paper and then measure its length with a ruler.
The result is your wrist circumference in centimeters.
Elastic Bracelets
Elastic bracelets are available in fixed sizes, listed in both centimeters and inches.
Choose the size that is closest to your wrist measurement, but never smaller than your measured wrist circumference. Your bracelet should fit comfortably – sitting neatly on your wrist without feeling tight or restrictive.
If your measurement falls between two sizes, choose the larger size.
If you prefer your bracelet to move more freely on your wrist, you may also choose one size larger than your measured wrist circumference.
If you're unsure which size to choose, feel free to contact us – we'll be happy to help you find the perfect fit.
Available sizes:
14 cm — 5.5 in
15 cm — 5.9 in
16 cm — 6.3 in
17 cm — 6.7 in
18 cm — 7.1 in
If you require a different size, a custom-made bracelet can be created upon request.
Silk Cord Bracelets
Bracelets made with silk cord feature an adjustable closure and fit most wrist sizes.
The adjustment range typically accommodates wrist circumferences of approximately 14–18 cm.
If your wrist is smaller or larger, please contact us – a custom size may be available.
Stretch Rings
Our rings are elastic and gently adapt to the finger. For the best comfort, however, we recommend choosing the correct size.
To measure your finger circumference, wrap a thin strip of paper around your finger, mark where the ends meet, and then measure the length.
Ring sizes are listed according to the European sizing system (finger circumference in millimeters).
