How do I date antique amethyst jewellery?

Dating relies on stylistic clues such as the flowing organic lines of Art Nouveau or the symmetrical geometry of Art Deco. Hallmarks stamped into the gold provide specific assay office and year markers. Changes in mount construction and gemstone cuts, from Georgian flat-cut to Victorian clusters, help narrow down the decade of manufacture.

What is the difference between 9ct and 15ct gold?

Fifteen-carat gold contains a higher proportion of pure gold than 9ct gold, yielding a richer warm hue. This higher purity standard is common in Victorian and Edwardian pieces before later legislative changes. Modern British hallmarking standards shifted away from 15ct, making those older gold mountings distinct markers of their era.

How should I care for antique amethyst jewellery?

Amethysts are durable quartz stones, but older settings involving seed pearls require gentle handling. Avoid ultrasonic cleaners and harsh chemicals, which can damage pearls and historical adhesives. Store pieces separately in lined boxes to prevent the gold and stones from scratching against one another.

Were amethysts worn for mourning jewellery?

Victorian mourning pieces occasionally incorporated purple stones to reflect periods of half-mourning. These items allowed wearers to display muted or sombre colours following the death of a relative. Such pieces often feature closed backs or compartment spaces intended to hold hair or miniature portraits.
