What image do you think can represent Jordan Baker's character from The Great Gatsby?
What about a cubic zirconia diamond? It's a fake diamond, because it's man made. It looks like a real diamond and has many similar properties, but it's fake.
Jordan Baker is a professional golfer. She's wealthy and glitzy. She's extremely attractive. She is desired by all kinds of men and a celebrity of sorts. She's a lot like a diamond. Flashy, well known, and worth a lot of money.
However, Jordan Baker is a liar and a cheat.
She was incurably dishonest.
She cheated in her first golf tournament, and she is a perpetual liar. She doesn't like to date clever men, because they see through her falsehoods. That's just like a cubic zirconia diamond. It looks nice and flashy, but it is not pure. It's fake . . . like Jordan.
