How do I date a vintage sapphire solitaire?

Dating relies on stylistic markers within the mounting, such as geometric platinum filigree typical of the Art Deco era or heavy yellow gold bands characteristic of the nineteenth century. Cut styles of accompanying diamonds and the method of stone setting also provide clear chronological indicators. Assay marks and hallmarks stamped inside the band offer definitive clues to the year and place of manufacture. Comparing the construction techniques against known periods helps narrow the origin down to specific decades like the nineteen-twenties or nineteen-fifties.

Are all sapphires in these rings blue?

While deep blue is the most common colour, sapphires occur in a wide spectrum of natural shades. The selections include green, orange, and purple variations alongside traditional blue tones. Geographical origin often influences the specific hue, with Ceylon stones known for bright vibrancy and Kashmir stones displaying a velvety saturation. Star sapphires also appear, showing optical phenomena within the cabochon cut.

What is the difference between platinum and white gold?

Platinum is a naturally white, dense, and strong precious metal that maintains its colour throughout. White gold is an alloy of yellow gold mixed with white metals like palladium or nickel, traditionally plated with rhodium to enhance brightness. In period jewellery, platinum was favoured for intricate Art Deco settings because of its structural resilience. White gold became more widespread in later mid-century manufacturing.

How should I care for a vintage ring?

Daily wear requires basic mindfulness, such as removing the ring during heavy manual labour or swimming to protect the setting. Regular checks by a professional jeweller ensure the claws holding the sapphire and any accent diamonds remain secure. Cleaning is best performed using warm soapy water and a soft brush to remove accumulated oils from beneath the stone. Ultrasonic cleaners should be avoided unless verified safe for treated or included gemstones.
