GUEST: It was given to me from my mother.
My mother was a German countess, and her ancestors started in Russia, and then, during the Russian Revolution, they fled to France.
GUEST: And at that time, they were supposed to have acquired this piece.
APPRAISER: In France?
GUEST: In France.
It was supposed to have belonged to Marie Antoinette, that's the story I got from my mother.
My mother was born in France.
And then they moved to Germany, and she was raised in a castle in Munich.
APPRAISER: You have five beautiful Burmese rubies here.
They're roughly somewhere around four carats, maybe four-and-a-half carats.
APPRAISER: In the trade, we call the best rubies pigeon-blood red rubies.
And that's what you have here.
APPRAISER: They're bright.
And they're not treated, they're natural, and... You know the bracelet was made in France.
GUEST: I was assuming that it was.
APPRAISER: Oh, okay.
GUEST: Since my mother told me that it was Marie Antoinette's, but... APPRAISER: Okay, well, Marie Antoinette never saw this bracelet.
(laughs) APPRAISER: The hallmarks, the double eagles in the head, tell you it was made in France and it's 18-karat gold.
APPRAISER: The gold is on the reverse side.
If you turn it over like that...
APPRAISER: You see the yellow gold.
The top, all the diamonds, they're very tiny full-cut diamonds.
They're set in platinum.
APPRAISER: So this is late 1800s when it was made.
Not Marie Antoinette.
APPRAISER: Not Marie Antoinette.
She could never have wore it.
APPRAISER: Ever wear this bracelet?
GUEST: No, my mother used to wear it all the time.
In fact, she left it in a car that my father sold.
And she realized that she had left it and went back the next day, and it was still in the glove box, so... APPRAISER: Oh, my God.
GUEST: (laughs) I guess I'm fortunate to still have it.
APPRAISER: A piece like this in today's market could easily sell for somewhere between $30,000 and $35,000.
GUEST: This piece?
APPRAISER: This piece, at auction.
GUEST (chuckling): Well, I'll hold onto it for a long time, then.
