Openwork, filigree scroll work of diamonds forms a high structure, acanthus leaves were worked into diamond-set borders and set accents. Another four sapphires are housed as highlights in the central motif, an exceptional jewel in the royal house’s treasury.
Like the complete diamond Parure, the tiara was revised in the 19th century by the renowned company Kreuter, Hanau specialist in white jewels, or supplemented with diamonds and precious stones from home jewelry.
