hip's captain, was bought by Prince Orloff for
L90,000, and given to the empress Catharine II. It weighs 194-3/4 carats,
is of a somewhat yellow tinge, and is among the Russian crown jewels.
The _Koh-i-nor_, which was in 1739 in the possession of Nadir Shah, the
Persian conqueror, and in 1813 in that of the raja of Lahore, passed
into the hands of the East India Company and was by them presented to
Queen Victoria in 1850. It then weighed 186-1/16 carats, but was recut in
London by Amsterdam workmen, and now weighs 106-1/16 carats. There has
been much discussion concerning the possibility of this stone and the
Orloff being both fragments of the Great Mogul. The Mogul Baber in his
memoirs (1526) relates how in his conquest of India he captured at Agra
the great stone weighing 8 mishkals, or 320 ratis, which may be
equivalent to about 187 carats. The Koh-i-nor has been identified by
some authors with this stone and by others with the stone seen by
Tavernier. Tavernier, however, subsequently described and sketched the
diamond which he saw as shaped like a bisected egg, quite different
therefore from the Koh-i-nor. Nevil Story Maskelyne has shown reason for
believing that the stone which Tavernier saw was really the Koh-i-nor
and that it is identical with the great diamond of Baber; and that the
280 carats of Tavernier is a misinterpretation on his part of the Indian
weights. He suggests that the other and larger diamond of antiquity
which was given to Shah Jahan may be one which is now in the treasury of
Teheran, and that this is the true Great Mogul which was confused by
Tavernier with the one he saw. (See Ball, Appendix I. to Tavernier's
_Travels_ (1889); and Maskelyne, _Nature_, 1891, 44, p. 555.).

The _Regent_ or _Pitt_ diamond is a magnificent stone found in either
India or Borneo; it weighed 410 carats and was bought for L20,400 by
Pitt, the governor of Madras; it was subsequently, in 1717, bought for
L80,000 (or, according to some authorities, L135,000) by the duke of
Orleans, regent of France; it was reduced by cutting to 1361-4/16 carats;
was stolen with the other crown jewels during the Revolution, but was
recovered and is still in France. The _Akbar Shah_ was originally a
stone of 116 carats with Arabic inscriptions engraved upon it; after
being cut down to 71 carats it was bought by the gaikwar of Baroda for
L35,000. The _Nizam_, now in the possession of the nizam of Hyderabad,
is supposed to weigh 277 carats; b
