How do I identify an old cut diamond?

Old cut diamonds display smaller tables, higher crowns and characteristic open culets visible through the back of the stone. These geometric differences separate hand-shaped stones from modern machine-cut brilliants. Examinations under magnification reveal irregular facet shapes and softer edge reflections unique to nineteenth and early twentieth-century lapidary work.

Are platinum and white gold different?

Platinum is a naturally white, dense and durable metal that develops a soft patina over decades of wear without losing substance. White gold is an alloy combined with other metals and typically plated with rhodium to maintain a bright finish. Over time, white gold may require replating, whereas platinum retains its native colour and structural integrity with basic maintenance.

How should I care for a vintage ring?

Vintage rings require gentle cleaning with warm water, mild soap and a soft brush to remove everyday debris from behind the settings. Professional inspections ensure that antique prongs and delicate millegrain remain secure. Avoiding harsh chemical dips protects softer accent stones like opals or unheated rubies often found alongside diamonds in historical cluster mounts.
