Find Your Perfect Fit: Why We Love Adjustable Rings
At HUMMINGBIRDFCSG, we believe jewelry should be as effortless as it is beautiful. That’s why we love adjustable rings — they take the guesswork out of sizing, making it easy for you to find your perfect fit every time!
Our adjustable rings are designed to comfortably fit between US sizes 4 to 10.
Here’s a quick guide to what those sizes mean:
US Ring Size | Inner Diameter (mm) | Circumference (mm) |
---|---|---|
4 | 14.8 mm | 46.5 mm |
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 | 57.0 mm |
9 | 18.9 mm | 59.5 mm |
10 | 19.8 mm | 62.1 mm |
Inner diameter measures the width across the inside of the ring, while circumference measures the full distance around your finger.
Why Adjustable Rings?
Flexibility: Perfect for days when your fingers feel a little different — warmer weather, cooler evenings, you name it.
Gifting Made Easy: No need to secretly find out someone’s ring size — adjustable rings make beautiful, stress-free gifts!
Layer and Stack: Wear on different fingers depending on your mood and style.
Quick Tip:
When adjusting your ring, do it gently to maintain its shape and beauty. A small tweak is all you need for the perfect fit!
