A truly beautiful and historical piece of jewellery! This diamond-shaped pendant with solid gold openwork and a central floral design exemplifies the characteristics of the creative Art Nouveau period.

The amethyst as the centre piece adds a touch of elegance and significance to the pendant. Amethyst is said to represent virtues like groundedness, tranquillity, and calmness, while also conveying strength and wit to those who wear it. For individuals born in February, amethyst is their birthstone, making it a symbol of personal empowerment and inner strength.

The pendant is marked "9ct" indicating that it is made of 9 carat gold, a common purity for gold jewellery. It's not uncommon to find slight colour variations in gold, and the slightly different shade of the newer 9ct yellow gold 45cm chain complements the pendant nicely.

The use of rose gold in the pendant adds a touch of sophistication and elegance. Rose gold is an alloy of pure gold mixed with other metals, such as copper and silver, to achieve its distinct warm pinkish hue. It gained popularity during the 19th century, thanks in part to the renowned jeweler Carl Fabergé, and it was highly valued among European nobility.

Complete with the vintage box photographed adding to the overall charm and nostalgia. 

Considering its age and the good used condition, this antique pendant holds both aesthetic and historical value. It's a lovely representation of the Art Nouveau era and would make a cherished keepsake or a thoughtful gift for someone who appreciates the beauty and significance of antique jewellery.
