FAQs

Eternity rings gained widespread popularity in the 20th century, symbolising everlasting love, with half-eternity versions offering increased comfort for daily wear by placing gemstones only across the top half of the band.

Traditional pieces are typically crafted from high-purity gold or platinum, set with natural blue sapphires and brilliant-cut or single-cut diamonds secured in claw, channel, or milgrain settings.

Authentic period pieces often feature hand-cut gemstones, makers marks or hallmark stamps specific to British assay offices, and subtle signs of artisanal metalwork such as hand-applied milgrain detailing.

This versatile piece can be worn stacked against a plain contemporary wedding band or engagement ring to create a contrast of textures, or worn alone as a subtle statement on the hand.

Fine jewellery should be cleaned periodically using warm soapy water and a soft brush to remove debris, avoiding harsh chemical ultrasonic cleaners on treated or inclusion-heavy gemstones.
