A 1679 violin made by Antonio Stradivari is headed for auction next month, where it is expected to reach a price over $10 million.
The "Hellier" Stradivarius "is the finest inlaid violin ever made by... Stradivari and one of the finest Stradivarius instruments in existence," said auction house Christie's.
What makes the violin really special is its decoration. The Hellier Stradivarius is engraved with ivory diamonds and finished with a golden varnish.
"Of the roughly 1,100 instruments Stradivari made over the course of his career, only around a dozen are embellished with decoration, and this specimen is regarded by the Smithsonian curators as the best-preserved extant example," Christie's said in a statement.
