How do I care for antique emerald jewellery?

Emeralds are relatively soft and contain natural inclusions, requiring gentle cleaning with a soft cloth rather than ultrasonic baths or harsh chemicals. Store pieces individually to prevent scratching from harder gems like diamonds. Protect the platinum or gold settings by avoiding impacts during wear. Periodic checks by a jeweller ensure the prongs holding the emeralds remain secure.

What metal is most common in 1920s jewellery?

Platinum dominated fine jewellery production during the 1920s due to its strength and bright white finish. This metal allowed artisans to fashion intricate, lightweight mountings. White gold and yellow gold also appeared frequently in rings and brooches. The choice of metal often reflects the specific workshop traditions and the date of manufacture.

How are Art Deco emerald rings identified?

Art Deco emerald rings feature geometric motifs, step-cut stones, and symmetrical arrangements of accent diamonds. Platinum or white gold mountings with millegrain detailing point directly to this era. Cluster designs and straight-line settings differentiate these items from Victorian or Edwardian predecessors. The presence of calibré-cut stones or baguette diamonds further confirms the period style.

Are these emeralds treated or natural?

Many period pieces incorporate natural emeralds, some accompanied by documentation noting minor oil treatments. Evaluators examine internal inclusions to determine the origin and treatment history of each stone. Natural Colombian stones appear alongside alternative green gemstones and paste substitutes in the broader marketplace. Each piece requires individual assessment to verify the exact nature of the green gems.
