Kenneth Jay Lane
The pics you see above are expensive jewelry in a panther shape most by Cartier.
The first one is a bracelet owned by the Duchess of Windsor,it's from 1952 and it's estimated 1.5 millin pounds.
This design is a symbol of the maison and never go out of fashion.
Even if we can't by these expensive shiny kitties we can anyway sport the look with much cheaper wild cats like the one you see above by Kenneth Jay Lane.
