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:


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!
