What is an intaglio seal fob?

How do I date Georgian and Victorian carnelian jewellery?

Dating relies on the combination of metal purity marks, stone cuts, and mounting styles. Georgian pieces often feature closed-back settings and neoclassical motifs. Victorian and Edwardian examples shift towards hollow-formed chains, rolled gold components, and bolder heraldic or classical intaglio carvings.

Can I wear a antique carnelian ring every day?

Carnelian is a durable chalcedony with a Mohs hardness of seven, making it suitable for regular wear. However, antique settings require mindful care. Avoid wearing antique rings during heavy manual tasks to protect the antique gold claws and the hand-carved stone surface from impact.

What is the difference between carnelian and red agate?

Carnelian and red agate belong to the same chalcedony mineral family and share similar orange-red hues. Carnelian tends to be a more uniform, translucent warm red. Agate often displays visible banding or contrasting layers of colour within the stone, though both materials appear interchangeably in antique fobs and brooches.
