At Custom Jewellery Designs, located at Shop 75, Whitford Shopping Centre, Hillarys WA, we offer a refined selection of 18ct gold jewellery including engagement rings, wedding bands, diamond and gemstone pendants, earrings, bracelets, and bangles. We also specialise in bespoke designs tailored to your personal style and story.

18ct gold is composed of 75% pure gold and 25% alloy metals such as silver, copper, or palladium. This blend offers a rich yellow hue, excellent durability, and is gentle on sensitive skin making it ideal for fine jewellery that’s both elegant and enduring.
