You've got to be a member of the Thieves' Guild, then get his ancient nord pickaxe back, and find the improved Bonemold recipe from that one guy's corpse in a Riekling cave. Then he'll give you a key to his basement (That sounds realy creepy...). That's where it is, along with a letter you can trade for an Exquisit Saphire, by giving it to the person of the same name, in the Theives' Guild Cistern.
