How do I identify a genuine 1930s piece?

Examine the construction methods and metal choices, as authentic items typically feature handmade platinum or white gold mountings with distinct Art Deco geometry. Look closely at the setting details, such as millegrain edges and hand-cut diamond shoulders, which reflect the manufacturing standards of the period.

Are these sapphires usually treated?

Many sapphires from this era are natural, though thermal enhancement has long been practiced to improve colour saturation in precious stones. Certification from established gemological laboratories often helps clarify whether a specific sapphire has retained its natural state or undergone heating.

How should I care for delicate antique settings?

Protect fragile platinum and gold mountings by removing rings and bracelets before engaging in strenuous physical tasks or housework. Clean the jewellery gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners that might loosen older stones.

What metals were most common during this decade?

Platinum was the premier metal of choice for fine gem-set pieces because its strength allowed for slender, intricate wirework and secure settings. Yellow gold and white gold also appeared frequently, particularly in rings and brooches produced during the latter half of the decade.
