FAQs

An old mine cut is a vintage diamond shape popular from the 18th to the early 20th century, characterised by a cushion outline, high crown, small table, and deep pavilion.

These pieces typically feature high-carat yellow gold or silver-topped gold settings, crafted by hand before the widespread use of platinum in fine jewellery fabrication.

Authentic pieces exhibit hand-cut facets that are irregular under magnification, open-backed settings, hand-stamped hallmarks, and signs of period wear appropriate to their age.

An antique ring can be paired with sleek, contemporary metal bands to create a mixed-metal stacked look that highlights the unique character of historical gemstones.

Clean these items gently using warm water, mild washing-up liquid, and a soft brush, avoiding harsh ultrasonic cleaners which can damage historical settings and fragile foils.
