How do I wear an art deco diamond pin today?

These pins attach securely to coat lapels, heavy knit sweaters, or silk scarves using traditional pin-stem and safety catches. Placing a small backing pad behind thick fabrics helps distribute the weight evenly. For formal wear, they fasten neatly to evening wraps or dress necklines, adding targeted points of light without pulling delicate materials.

What is the difference between platinum and white gold in these pieces?

Platinum offers natural white strength and density, allowing jewellers to create ultra-fine wire structures that hold stones securely without heavy metal bulk. White gold alloy mixes yellow gold with white metals to achieve a similar silver tone. Over decades, platinum retains its hue without plating, whereas early white gold often shows a warmer underlying tint.

Are these pins suitable for daily wear?

While platinum and gold provide durable mountings, the delicate box catches or pin stems require careful handling during fastening and removal. Regular checks by a jeweller ensure the stone settings remain secure. Avoiding exposure to harsh chemicals and storing them in dedicated boxes preserves the integrity of the metal and fragile calibré-cut stones.

How can I tell if the gemstones are original?

Original stones display hand-cut facets matching the period's production methods, such as old European cuts with open culets. Examining the bezels under magnification reveals consistent wear and secure metalwork that has not been recently rebuilt. Colour consistency and matching inclusions across accent stones like sapphires or onyx further confirm period assembly.
