The Sustainable Choice

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

FAQs

An old mine cut diamond ring from this era typically features a hand-faceted stone with a slightly squarish cushion shape, a high crown, a small table, and a deep pavilion. During the 1920s, these cuts were often set in transition-era mountings combining yellow gold shanks with platinum settings.

Jewellers during the 1920s predominantly utilized yellow gold, white gold, and platinum. It was common practice to craft the band out of yellow gold while securing the diamond in a white metal head to emphasize the stones white tone.

Authentic pieces feature asymmetrical hand-cut facets, an open culet visible through the top of the stone, and characteristic period hallmarks on the interior band. The setting craftsmanship often exhibits delicate hand-finishing, such as claw prongs and decorative collar shoulders.

A vintage solitaire ring can be styled by pairing it with a simple contemporary metal band or mixed-metal stacking rings. The timeless geometry of an old cut stone allows it to complement both minimal modern attire and classic formal wear.

Clean the piece using warm water, mild soap, and a soft-bristled brush to remove dust from behind the stone. Have a professional jeweller check the integrity of the setting claws annually to ensure the diamond remains securely held.
