Diamonds. 

 The " Shah " (86 carats), belongs to Russia : — 

 Akbar (Mogul Emperor, 1556-1605). 

 ISTizam Shah (dynasty lasted 1490-1636). 

 Fath Ali Shall (Shah of Persia, 1798-1834). 



Jahangik's (116 carats) ; reduced, by cutting, to 71 or 72 carats, and 

 sold to Gaikwar of Baroda : — 



Jahangir (Mogul Emperor, 1605-1627) ; a.h.1028, a.d. 1619. 

 Shah Jahan, Sahib Kiran Sani (Mogul Emperor, 1628-1658) ; 

 a.h. 1039, A.D. 1629. 



Dakta-i-ntjr (186 carats, ?) ; belongs to Shah of Persia : — 

 Eath Ali Shah (Shah of Persia, 1798-1834). 



The deductions to be drawn from the names and dates in. the 

 preceding list are as follows : — Akbar's name was engraved on the 

 "Shah" diamond on Timur's (or the Throne) ruby, and on Lady 

 Carew's ruby without any accompanying dates so far as is known. It 

 was also engraved on what we call Nadir Shah's ruby in a.h. 1009 

 (= A.D. 1600). Another name engraved on the '' Shah" diamond was 

 that of the Nizam Shah, so that probably it was taken from or con- 

 ferred upon him by Akbar and was subsequently taken to Persia, not 

 necessarily by Nadir, but on some previous occasion, perhaps a century 

 before his time. Then about the beginning of this or the end of the 

 last century, it was engraved with the name of the then ruling 

 monarch of Persia, Eath Ali Shah. Thus it was possibly never in 

 the possession of any of Akbar's successors, the Mogul Emperors, 

 as has been already suggested. 



I have long had in preparation the full histories of the " Shah," 

 and many other Indian diamonds : here it need only be said that this 

 one was presented to the Czar Nicholas of Eussia in the year 1829 or 

 1830, by Prince Khusru in deprecation of his anger at the murder of 

 his ambassador at Teheran. 



Jahangir's name with the honorific prefix " Shah Akbar," and in 

 a very similar style of monogram engraving, is dated as follows on : — 



Nadir Shah's ETJBY, . a.h 1016? (a.d. 1607). 



Lady Carew's ruby, . a.h. 1021. (a.d. 1612). 



Jahangir's diamond, . a.h. 1028. (a.d. 1619). 



Jahangir's name was also, as we have seen, engraved on the ruby 

 which he gave to Shah Jahan, who had it mounted in the peacock
