It's auction time again. See the two stunning stones that are causing a stir this time around.
The first stone comes in the guise of a large emerald and diamond brooch once worn by one of the world's most powerful and ruthless female leaders, Catherine II of Russia. The hexagonal-cut stone weighs between 60 and 70 carats and is surrounded by rose and old mine-cut diamonds. The estimated price for this little beauty clocks in at around $1 to $1.5 million.
