The Volcanic Signet Ring is inspired by the ancient volcanic plugs of the Glasshouse Mountains. These rustic rock formations, extending all the way to the beaches of the Sunshine Coast, have been beautifully weathered by crashing waves. This ring embodies the perfect balance of brutality and elegance, mirroring the rugged beauty of its natural inspirations.
Unlike other blackened silver rings that lose their surface over time, the Volcanic Signet Ring is crafted to last a lifetime without changing. The design ensures that while the polished high points remain clean and bright through gentle buffing by your hands, the blackened channels stay untouched, preserving the ring’s striking contrast and unique appeal.

How to measure at home — Cut a thin strip of paper and wrap it snugly around the finger you plan to wear the ring on. Mark where the paper overlaps, then measure that length in mm — this is your circumference. Find that number in the Circumference column above to identify your size. If you fall between two sizes, we recommend sizing up. For wider band styles, also consider going up one size.
Jack Lewis –
I went to the Carseldine markets this weekend and bought a lovely signet ring from the Kaikoa designs stall and enjoyed learning about their story! From how the jewellery were all individually handmade and unique. The customer service was absolutely amazing, engaging and was great getting to know Marc. The kind customer service and great atmosphere that was provided quickly convinced me to purchase a 1 of 1 unique bespoke piece. Thank you Marc and Kaikoa Designs, I’ll sure to be back 🙂
