Frequently Asked Questions

How do I choose the correct Gecko ring size?

Gecko ring sizes correspond to the internal circumference in millimetres. For example, a size 50 ring has an internal circumference of 50 mm. If your measurement falls between sizes, choose the next size up for comfort.

What are the sizing considerations for wide bands?

Wide bands cover more of the finger, so they feel tighter than a narrow ring in the same size. Many people prefer going up a ring size for wide styles over 8 mm.

Are the rings engravable?

Yes. Most plain bands and many signet rings are engravable. Engraving is usually possible on the inside of the band, the outside of a plain band, and the face of signet styles. Check the product page for specific guidance.

How do I choose the correct chain length?

Start with how you plan to wear the chain, then match the length to your neck size and neckline. As a rough guide, most women prefer 41 to 46 cm for everyday wear and pendants, while men often choose 46 to 56 cm depending on build and style.

What are the best length chains for layering?

Aim for 2 to 4 cm between each chain so they sit neatly without tangling. If possible use an extendable chain to fine tune gaps. Three layers is a sweet spot for most necklines.
