While this is quite a respectable carat weight, it's still only a fraction of the size of the current world's-largest-diamond champion, the Cullinan diamond, which was unearthed in 1905 and weighed a whopping 3,106 carats before being broken apart and made into a whole bunch of the British crown jewels.
