Queen Therese of Bavaria wears an elaborate diamond tiara featuring diamond drops, scrolls, and laurel leaf motifs in its design, plus her pearl girandoles and the pearl crown of Bavarian queens, in a copy of Joseph Karl Stieler’s coronation portrait; I don’t have any additional information about the tiara, but the earrings and crown are both featured here!

Queen Caroline of Bavaria wears a parure of jewels with gem-set clusters, possibly featuring black opals, hematite, or onyx, in a portrait by an unnamed German artist, ca. 1817; I do not have any additional information about the jewels depicted
