The instriptions in the Arabic Naskh script is a perfect example of ancient Arabic calligraphy laid out symmetrically in five rows, with the upper introductory row being a little wider than the remaining four rows of equal width. The edges of the rectangle are carved with cross pattern incisions and herringbone pattern decorations.

The dimensions of the emerald are 52 x 40 x 12 mm, and the mid-point of each of the four sides of the rectangle has been drilled for attachments, so that the gemstone could be mounted and worn as a talisman, with the Arabic inscriptions facing outwards.

THE HOOKER EMERALD

The emerald was used by the sultan to decorate a belt buckle until it was purchased by Tiffany & Co in 1911 and was made into a brooch. The brooch has 109 round diamonds and twenty baguettes, the combined weight of the diamonds are 13 carats. Mrs Janet Annenberg Hooker (sister of Walter Annenberg) purchased the emerald brooch from Tiffany in 1955 and donated it to the Smithsonian Institute in 1977.

THE SPANISH INQUISITION NECKLACE

Neither the origin nor the name of this necklace can be substantiated. We know that parts of the original necklace are over three hundred years old, and some believe its gemstones to have once belonged to the Spanish royal family. Is 374 diamonds must have come from India as India was the only diamond source at that time. There are 15 emeralds, the largest of which is 45 carats, all of which came from Colombia. According to experts the necklace that exists today was probably created in the twentieth century, judging from its style. The Maharaja of Idore owned the necklace until 1948 when it was purchased by Harry Winston. The necklace became part of the National Gem Collection when it was donated to the Smithsonian Institute by Cora Hubbard Williams in 1972.
