How do I care for a platinum ring?

Platinum develops a soft surface patina over time through normal wear, which many collectors prize for the authentic antique character it imparts. Regular cleaning in warm soapy water keeps the metal bright and prevents lotions from dulling the stone facets. Avoid wearing antique rings during strenuous physical activities to protect delicate claw settings and softer organic gems like pearls or opals from impact.

Can these rings be resized?

Most platinum and gold rings can be adjusted by a skilled jeweller who understands antique construction methods. The process involves adding or removing a small section of the shank. Intricate side engraving or continuous channel-set stones can limit how much a ring can be altered without disrupting the original design.

What is an old cut diamond?

An old cut diamond refers to stones shaped by hand before modern machinery standardised gemstone proportions. These cuts feature smaller tables, steeper crowns, and larger culets that produce a distinctive, warm sparkle. Such stones were tailored individually to maximise the rough crystal's weight rather than adhering to rigid mathematical formulas.

How do I date an antique ring?

Dating relies on a combination of stylistic markers, such as the geometric symmetry of Art Deco work or the flowing motifs of the Edwardian era. Hallmarks stamped inside the band provide official assay marks and maker signatures when present. Stone cutting styles and mounting techniques offer further physical evidence that narrows the period of manufacture.
