Though a comparatively small stone, in weight 25½ carats, it is noted for its perfection of form and quality. It belongs to the Archduke Franz Ferdinand of Austrian-Este, eldest son of the Archduke Karl Ludwig.
(21) Tuscany, or Austrian Yellow
The beauty of this large stone, 133¾ carats in weight, is marred by the tinge of yellow, which is sufficiently pronounced to impair its brilliancy; it is a double rose in form. At one time the property of the Grand Dukes of Tuscany, it is now in the possession of the Emperor of Austria. King mentions a tale that it was bought at a curiosity stall in Florence for an insignificant sum, the stone being supposed to be only yellow quartz.
(22) Star of the South
This, the largest of the Brazilian diamonds, was discovered at the mines of Bagagem in July 1853. Perfectly transparent and without tint, it was dodecahedral in shape and weighed 254½ carats, and was sold in the rough for £40,000. It was cut as a perfect brilliant, being reduced in weight to 125½ carats.
(23) English Dresden
This beautiful stone, which weighed 119½ carats in the rough, was found at the Bagagem mines, in Brazil, in 1857, and came into the possession of Mr. E. Dresden. It was cut as a long, egg-shaped brilliant, weighing 76½ carats.
(24) Star of South Africa
The first considerable stone to be found in South Africa, it was discovered at the Vaal River diggings in 1869, and weighed 83½ carats in the rough. It was cut to a triangular brilliant of 46½ carats. It was finally purchased by the Countess of Dudley for £25,000.
