Two Stradivarius instruments, a violin valued at $1.3 million and a cello estimated to be worth over $800,000, hit the auction block this week in London. As usual, there is little chance that either instrument will be purchased directly by anyone who can play them, as most of the world’s high-end instruments are now bought and sold by collectors, who may choose to lend them out to performers, or not. Earlier this week, another million-dollar Strad violin failed to sell at auction when no one met the asking price.
