Bloodstone

Definition and stakes

L. T. Meade and Robert Eustace,  The Sorceress of the Strand — The Bloodstone (1903)

“ The bloodstone, the priceless talisman of the Royal House of Persia, had been stolen. The confusion was appalling, and already someone had gone to fetch the local police.
"I shall lose my life if the stone is not recovered," cried the miserable Persian, despair and terror depicted on his face. "Who has taken it? The other gems are safe, but the secret drawer has been burst open and the bloodstone removed. Who has taken it? Sir John, what is the matter?—You look strange."
"I can throw light on this mystery," said Sir John.
I looked around me. Neither Lady Bouverie nor Madame Sara was present.

“ A good deal of bloodstone comes from India, where it occurs in the Deccan traps, and is cut and polished at Cambay. The stone is used for seals, knife-handles and various trivial ornaments. Bloodstone is not very widely distributed, but is found in the basaltic rocks of the Isle of Rum in the west of Scotland, and in a few other localities. Haematite (Gr. αἷμα, blood) , or native peroxide of iron, is also sometimes called “bloodstone.” ”

“ The most valuable kinds of bloodstone are imported from the East. They are not so opaque as those which are found in Germany, and are marked with more vivid spots. As bloodstone is capable of a high polish, and is even better calculated for engraving upon than carnelian (93) , it is in great request for seal stones, for the tops and bottoms of snuff-boxes, and other articles on which costly gold mountings are frequently bestowed. Its dark colour and opaque appearance prevent its being much used for beads. ”
