FAQs

Old cut diamonds, such as old European or old mine cuts, were hand-cut prior to modern machinery, featuring smaller tables, higher crowns, and larger culets that create a distinctive candlelight sparkle.

These rings are traditionally crafted from high-karat yellow gold or white gold, often pairing white metal settings like platinum or white gold around the diamonds to enhance their perceived brightness.

Authentic pieces typically exhibit hand-carved settings, characteristic wear consistent with age, traditional solder marks, and hallmark stamps that correspond to historical assay office records.

An antique ring pairs effectively with contemporary minimalist attire to create a striking contrast, or it can be stacked with modern bands for an eclectic, textured look.

Clean these items gently using warm water, mild washing-up liquid, and a soft-bristled brush, avoiding harsh ultrasonic cleaners which can loosen older stones in their hand-crafted settings.
