The most expensive ring in the world is the Chopard Blue Diamond Ring, priced at $16.26 million.
Did you know that blue diamonds that are usually found among boron deposits (from where it inherits a blue shade) are one of the most rarest and expensive diamonds? The Chopard Blue Diamond Ring has one that weighs in at nine carats that can make any girl go gaga over it!! The ring features an enormous, oval-shaped blue diamond, with diamond shoulders and an 18k white gold band paved with diamonds.
This ring can make any other ring look insufficient and ordinary or rather should I say you have a safe bet with this ring to charm and win over the girl you love.
