Rowan – Custom Parti Colour Sapphire Signet Ring
Meet Rowan, a distinctive custom parti-colour sapphire signet ring from our Men’s Collection, handcrafted in platinum with a clean, contemporary silhouette designed to be worn by anyone.
At its centre is a 0.73ct emerald-cut parti-colour sapphire, sourced and cut in Inverell, NSW. Its naturally occurring green and blue tones make every angle of the gemstone feel different, giving the ring an individual character that cannot be replicated.
The sapphire is elegantly bezel-set into a substantial platinum signet-style setting. Strong architectural lines give Rowan a distinctly modern presence, while its understated proportions make it refined enough for everyday wear.
Although featured within our Men’s Jewellery Collection, Rowan's minimal, sculptural design is naturally unisex, making it an exceptional choice for anyone drawn to Australian sapphires, contemporary signet rings and jewellery with individuality.
Parti-colour sapphires are celebrated for displaying more than one natural colour within a single gemstone. Each stone has its own unique colour zoning, making every parti sapphire—and every ring created around it—truly one of a kind.
