What is the difference between white gold and platinum pieces?

Platinum is naturally white, exceptionally dense, and strong enough to support fine, intricate wirework without bending. White gold is an alloy mixed with other metals to achieve a pale tone and tends to feel slightly lighter on the garment. While both metals visually complement the 1920s aesthetic, platinum was the premier choice for top-tier jewellery of the period due to its superior durability and prestige.

Can these pins also be worn as pendants?

Certain examples are constructed with hidden bails or loops on the reverse, allowing them to transition seamlessly from a lapel brooch to a pendant hung from a chain. This dual functionality was a clever feature appreciated by jewellers and buyers of the period. Check the reverse of the piece for hinged loops or fitted attachments if you wish to wear it around the neck.

How should I clean my antique diamond pin?

Soak the piece briefly in warm water mixed with a few drops of mild washing-up liquid, then gently brush around the stones and settings with a very soft toothbrush. Avoid harsh chemical dips, particularly if the brooch incorporates softer natural materials like pearls, onyx, or turquoise. Pat the jewel thoroughly dry with a soft lint-free cloth before storing it in a lined jewellery box away from other pieces.
