The egg is made of gold, covered in pink enamel over a guilloché ground. On it's sides sits rose-cut diamonds, from which hangs crossed laurel swags. The top of the lid is set with a domed rock crystal, surrounded by rose-cut diamonds. To open the egg you use the cabochon emerald thumbpiece seen in the middle. The size of the egg-box is 1.6'' x 1.1'' (4 x 2.7 cm), and it was acquired by Queen Mary, sometime before 1920. Now it's part of the Royal Collection.
