Vintage Australian 18ct Yellow Gold Diamond And Sapphire Ring Circa 1940-50
Please note, boxes are for display only unless otherwise stated.
This vintage Australian 18-carat yellow gold ring is a charming and wearable piece of jewellery with a touch of history. At its centre sits a square-cut Sapphire of approximately 0.14 carats, its rich blue hue beautifully complemented by four round brilliant-cut diamonds—two on either side—together weighing approximately 0.20 carats. The combination of sapphire and diamond creates a timeless contrast of colour and sparkle, making this ring both elegant and versatile.
One of the most appealing features of this piece is its low-rise profile. Sitting close to the finger, it is exceptionally comfortable to wear and pairs seamlessly with other rings, whether stacked alongside a wedding band, worn with an eternity ring, or simply enjoyed on its own. Its understated proportions make it an easy everyday choice while still offering a refined touch of vintage glamour.
Adding further intrigue are the hallmarks inside the band: “Hand Wrought,” “18CT,” an “X,” and a maker’s mark of an “M” within a circle. These marks suggest the ring was crafted by either Mackay & Co. of Queensland or S. Middlewick of Western Australia, both respected names in Australian jewellery history.
Beautifully made, full of character, and delightfully easy to wear, this ring is a wonderful example of Australian craftsmanship—an elegant vintage piece that feels just as relevant today as when it was first created.
