How do I date a square gemstone ring?

Dating relies upon examining the mounting style, metal combinations, and gemstone cuts present in the piece. Edwardian examples often feature delicate platinum-topped gold work, whereas Art Deco pieces show strict geometric symmetry. Mid-century rings frequently scale up in size, introducing substantial aquamarines or bolder cocktail proportions. Hallmarks and specific setting techniques further clarify the manufacturing period.

What metals are used in these rings?

Platinum and various grades of gold form the structural foundation of these antique and vintage rings. Platinum gained preference in the early twentieth century for its strength and bright white finish. Yellow gold frequently appears in shanks and earlier Edwardian mountings, sometimes paired with white metal gallery tops. Fourteen-carat and eighteen-carat alloys provide durability for daily wear.

Are the coloured gemstones treated?

Treatment varies significantly depending on the stone type and the era in which the ring was made. Certain emeralds and sapphires carry certification noting the presence or absence of oils and heat treatments. Historical stones often retain their original natural characteristics, while documentation on modern laboratory reports details any clarity enhancements. Examining specific certificates provides precise data on gemstone treatments.

How should I care for an antique ring?

Regular inspection by a professional jeweller ensures that claws and settings remain secure around the central stones. Gentle cleaning with warm soapy water and a soft brush maintains metal and gemstone brilliance. Avoiding harsh ultrasonic cleaners protects fragile emeralds and treated stones from damage. Storing the ring separately prevents scratching from other jewellery items.
