A gem merchant said the stone was found in the gem-rich Ratnapura area.
Experts say the stone, which is pale blue in colour, has an estimated value of up to $100 million in the international market.
The cluster weighs around 510 kilograms or 2.5 million carats and has been named the "Serendipity Sapphire".
I have never seen such a large specimen before. This was probably formed around 400 million years ago," Dr Gamini Zoysa, a renowned gemmologist told the BBC.
