UMDAT UTTWARIKH, lit. the choicest of histories, by Sohan Lal Suri, is a chronicle, in Persian, primarily of the reigns of Ranjit Singh and his successors. The original manuscript, in five volumes in shikastah hand, consisted of some 7,000 pages. A lithographed edition of the work was brought out, in 1880, by the author`s descendants, under the auspices of the Panjab University College, Lahore. The Registrar of the College, G.W. Leitner, had in fact taken the manuscript with him to the International Congress of Orientalists (1879) held at Florence where it was put on display :the manuscript was then returned to Harbhagvan Das, the grandson of the author, from whom it had been borrowed.
KOHINUR ("Mountain of Light"), the peerless diamond which today lakes the pride of place among the British crown jewels, once belonged to Maharaja Duleep Singh, the last Sikh sovereign of the Punjab. Duleep Singh was made to surrender it to the British after the annexation of the Punjab in 1849. The stone, which weighed 1861/6 carats, was exhibited in London in 1851. In 1852, it was entrusted for recutting to a London firm of jewellers who engaged for this purpose a Dutch from Amsterdam. The cutting enhanced the brilliance of the diamond, but reduced its weight by 80 carats.
