The tiara features single, rose-cut and brilliant-cut diamonds and three fluted turquoise plumes set with diamond stems, according to Bonhams.

For those keeping count, that’s 345 rose-cut aquamarines, 37 white topaz, 27 tourmalines, 12 rubies, seven amethysts, six sapphires, two jargoons, one garnet, one spinel and one carbuncle, which is not to be confused with a carbuncle, a type of abscess.

The museum houses treasures such as a salvaged tearoom designed by Charles Rennie Mackintosh and a tiara of rose-cut diamonds with a pair of wings which tremble slightly when worn.

Among them will be a pearl necklace with rose-cut white diamonds and natural fancy pink diamonds, highlighting the house’s expertise in matching pearls and finding diamonds with the same color, cut and purity.
