Step into a world of bold sophistication with this past design from our archives. This substantial men's ring features a striking Black Star Sapphire, a gemstone renowned for its deep, midnight hue and rare asterism (star effect) that shifts in the light.
Set in a heavy, gold-toned band with distinct ribbed detailing on the shoulders, this piece exudes a vintage, "gentleman's club" aesthetic.

We are thrilled to present this exceptional 1.85-carat Oval Emerald. Sourced for its vivid green hue and superior clarity, this stone captures the true essence of luxury.
Unlike many emeralds that rely on heavy treatment, this piece stands out for its natural vibrancy and "garden-like" internal character (inclusions) that proves its authenticity. Perfect for a bespoke high-end ring or a standalone addition to a serious gem collection. https://bit.ly/3OH0vS1

There is more to DIANA than its vivid blue centre.

The diamonds surrounding its 1.3 ct unheated blue sapphire are specially drilled to create kinetic movement around the halo. This petal-like surround adds a moving detail to the familiar sapphire-and-diamond silhouette.

DIANA is crafted in 18 kt white gold with 1.668 ct of diamonds in total. Contact AUTIUM in Singapore to enquire about AU398 and viewing arrangements.
