How do I care for my ring?

Emeralds are softer than diamonds and require gentle cleaning with warm soapy water rather than ultrasonic machines. Regular checks by a jeweller ensure the claws holding the stones remain secure. Storing the piece separately from harder gemstones prevents scratching. Avoiding harsh household chemicals protects both the metal mount and any fracture-filling treatments in the emerald.

Can I resize an antique band?

Many platinum and gold rings can be adjusted by a skilled jeweller, depending on the band thickness and setting style. Designs featuring channel-set stones around the entire hoop present greater sizing challenges. Consulting a specialist ensures the structural integrity of the shoulders and gallery remains intact during alteration. The presence of hallmarks or delicate engraving may also influence how much the band can be adjusted.

What does oil treatment mean?

Natural emeralds commonly contain internal fractures that are routinely treated with colourless oil or resin to improve clarity. Certification documents specify whether this filler is minor, insignificant, or moderate. Gradings noting minor or negligible oil indicate a higher proportion of natural clarity. This factor often contributes to the desirability and character of the gemstone.

How do I identify the period?

Stylistic markers such as geometric platinum scrollwork point toward Art Deco creation, while delicate millegrain edges often signal Edwardian or Victorian work. Examining the construction of the basket and the cut of the diamonds helps narrow down the decade. Assay marks and maker's stamps inside the shank offer further chronological clues. Comparing the mounting technique with known historical periods clarifies the age of the piece.
