Description

A beautiful Edwardian Art Nouveau rosy gold brooch with fiery heart-shaped opals and a trio of vivid green demantoid garnets. The clover, or three-leaf shamrock, traditionally symbolises faith, hope and love and has also long been an important symbol in Irish, Celtic, Pagan and Christian cultures. The brooch comes complete with the antique silk-lined Gieves case pictured, which may be its original home.

SIZE: 2.3 x 2.5cm.

WEIGHT: 3.9g.

MATERIALS: 15-carat gold, opal, demantoid garnet.

HALLMARKS/STAMPS: Marked 15CT on the reverse. Fifteen-carat gold pieces are not overly common (in the UK only really used between 1854 and 1932) and this fineness was generally used in high quality pieces.

CONDITION: The brooch is in excellent antique condition. The box is in great condition but has some pen marks inside the lid.

ERA: Estimated Edwardian (c.1901-1914).

FAQs

Edwardian Art Nouveau jewellery is characterised by flowing, organic lines inspired by natural forms such as plants, flowers, and insect wings, typically executed with delicate craftsmanship and precious gemstones.

Pieces from this period frequently utilised high-carat gold, such as 15ct, alongside platinum settings that allowed for intricate openwork, paired with coloured gemstones like opals, demantoid garnets, and pearls.

Authenticity is often indicated by period-appropriate hallmarks denoting gold purity, hand-fabricated construction techniques, traditional safety catches, and the characteristic use of natural untreated gemstones.

Antique brooches can be styled contemporary by pinning them to coat lapels, securing scarves, fastening silk blouses, or wearing them as pendants on modern chains.

Opals are relatively soft and sensitive to thermal shock and harsh chemicals; they should be cleaned gently with a soft cloth and stored separately from harder gemstones to prevent scratching.
