The SARAH & SEBASTIAN engagement ring journey is guided by considered design, exceptional craftsmanship, and a deeply personal approach. From contemporary silhouettes to refined interpretations of classic forms, each bespoke ring is designed in-house and made to order, with meticulous attention to detail.

Once your diamond or gemstone is secured, our design team creates a precise CAD model tailored to your specifications. Your ring is then handcrafted in Sydney by a master jeweller. From hand-setting stones to the final polish, our process ensures an exceptional level of Australian craftsmanship.

All of our natural diamonds are GIA certified, the world’s most respected authority on diamond grading. Each stone is assessed for the 4Cs: cut, colour, clarity, and carat weight, providing complete transparency. This certification ensures your diamond is ethically sourced and professionally evaluated for lasting quality and integrity.

We work exclusively with trusted suppliers who share our commitment to ethical sourcing. Every gemstone is selected for its quality, durability, and origin. We prioritise supply chain transparency and environmental impact, ensuring every stone meets our standards for beauty and responsibility before it becomes part of your piece.

Every SARAH & SEBASTIAN engagement ring is guaranteed by a 36 month warranty against manufacturing faults. To ensure your piece remains in pristine condition, we offer a lifetime of complimentary professional cleaning and annual checks at any of our flagship boutiques. We provide one complimentary resize on all SARAH & SEBASTIAN engagement rings within three years of the date of final payment.

Every engagement ring is encased in our signature aluminium shell. Designed to be a forever keepsake, your shell serves as a cherished trinket box and can be custom engraved with initials or a significant date to mark your moment in time.
