Albert found a stone in his yard and took it to Bob, a jeweler, for evaluation. Although Bob knew what the stone was, he told Albert that he wasn’t sure as to the nature of the stone, but that he thought it was a topaz. Bob then offered to buy the stone for $25 and Albert agreed. Later Albert found out the stone was an uncut diamond worth about $700.
