Diamond necklace/tiara, late 19th Century

Designed as a line of trefoil motifs set with rose- and circular-cut diamonds, suspending at the front graduated knife-edge bars tipped with circular-cut stones,

'Tiaras were very much in fashion in the last two decades of the 19th century and necklaces were often provided with a special rigid frame to enable them to be worn as a tiara'. For further details, please refer to David Bennett and Daniela Mascetti, Understanding Jewellery, Antique Collector's Club, pages 204 to 210.

French assay marks for gold. Total diamond weight approximately between 15.00-20.00 carats, the principal circular-cut diamond weighing ca. 1.35 ct. Mixed in colour and clarity. Weight, colour and clarity difficult to assess due to rose-cutting. Signs of normal wear and scratches commensurate with age of the piece. Well preserved, in good condition.
