GARDNER, ALEXANDER HAUGHTON CAMPBELL (1785-1877). son of a Scottish immigrant, was, according to an autobiographical account, born in North America in 1785. As a boy, he learnt Italian, Spanish, Latin and Greek, and proceeded in 1807 to Ireland to train for a maritime career. Returning to America, he set out on a journey to Astrakhan where his elder brother was in the Russian service. In 1817, he left Russia and after wandering for many years in Central Asia, drifted to Afghanistan where he took up service under Amir Habibullah Khan.
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.
