Modena Sculptural Gold Bangle

Find Your Perfect Fit
Before selecting your ring, be sure to measure the correct finger on the correct hand — sizes can vary between hands. For the most accurate results, measure when your hands are warm, as cold temperatures can cause your fingers to shrink slightly. And don’t forget: the ring should comfortably pass over your knuckle without being too loose.

Measure an Existing Ring
Choose a ring that already fits the finger where you plan to wear your St geran ring.
Using a ruler or measuring tape, measure the inner diameter of the ring.

Record the measurement in millimetres.

Refer to our ring size chart above to find your corresponding size.

We use standard US sizing. For approximate conversions, refer to the table below. You can also purchase our ring sizer for greater accuracy.

Hypoallergenic Jewellery
At St Geran, our jewellery is thoughtfully crafted to be hypoallergenic, nickel-free, and lead-free, making it suitable for most sensitive skin types. Each piece is designed to feel as good as it looks, minimising irritation and promoting everyday comfort.
If you have a known allergy or material sensitivity, we recommend reviewing the Materials section on each product page for specific details.

18k Gold Plated & 925 Silver Plated Jewellery
Our 18k gold plated pieces are crafted by applying a rich layer of 18k gold over a quality base metal, most commonly copper, and occasionally stainless steel.
Similarly, our 925 silver plated designs feature a fine layer of genuine 925 silver plated over carefully selected base materials, such as brass or copper, creating a bright, polished finish.
While these finishes are created for durability, plated jewellery is naturally delicate and may fade or tarnish over time with exposure to moisture, chemicals, or frequent friction.

Care Instructions
To Preserve Your Pieces:
Avoid contact with perfumes, lotions, hairspray, and household cleaners
Remove jewellery before showering, swimming, or exercising.
Store pieces in a cool, dry place—ideally in a soft-lined jewellery box or anti-tarnish pouch, away from direct sunlight.
Use the anti-tarnish tab provided with your purchase to protect against moisture during storage.

To Clean:
Gently buff using a soft, dry polishing cloth.
Avoid abrasive materials or harsh polishing agents that may wear down the plating.
