The story

Ratnapura means city of gems. The alluvial gravel under the paddy fields — illama, locally — has been worked since antiquity by men going down hand-dug shafts propped with rubber logs and sending baskets up on a rope. It is not mechanised, and the reason is not sentiment: the deposits are pockets, and a machine that moves enough ground to be worth running destroys more stone than it finds.

This is a Ceylon blue sapphire, a little under a carat and a half, cut as an oval. Ceylon blue is typically lighter and brighter than Burmese or Australian material, and the thing to look for is evenness — sapphire often grows in bands of colour, and a stone that shows no zoning face-up has been oriented correctly by whoever cut it.

Set in six claws so the maximum amount of light can get underneath, in recycled silver. Ranjith sets his own stones, which is unusual; most cutters hand off to a setter and most setters never see a rough stone.
