GUEST: I inherited this necklace from my grandmother.

She was born in 1900 and she lived until she was 102.

APPRAISER: Wow.

GUEST: So I got it in 2002.

My grandmother grew up in Sedalia, Missouri, and then she was a woman ahead of her time.

She went to college in Chicago and then worked at Northwestern University.

Then she got married and moved to New Rochelle, New York.

So she must have gotten the necklace either in New York or Chicago.

APPRAISER: How'd she come by it?

GUEST: I don't really know, but she was a really independent woman.

In fact, one of the pieces of advice that she gave me was, a woman should always have her own money.

So she might have bought it for herself.

APPRAISER: Very nice-- yeah, that's, that's impressive.

Especially in those times.

GUEST: It s, she sure was.

All right.

APPRAISER: It's from a famous Danish designer.

His name is George Jensen.

He's really well-known for his early career in silver design.

He started in Copenhagen, and his original motifs were basically very natural.

He would make brooches and jewelry with deer motifs and tulip motifs.

George Jensen did pass away in 1935.

The company continued on.

To this day, you can still buy George Jensen jewelry.

It is from the mid-century, the late '50s, early '60s.

It's marked on the back.

It has his classic signature the company adopted after the 1940s.

GUEST: Okay.

APPRAISER: Which is his name with this oval shape of dots surrounding it.

GUEST: Got it.

APPRAISER: It's very iconic.

GUEST: Okay.

APPRAISER: And it says "750 18K"-- which is the same thing.

The Europeans mark their gold 750 when it's 18K.

And it's model number 7104.

And we see that marked on the clasp.

Pieces similar to this are selling in the $12,000 to $14,000 range.

GUEST: Wow!

(chuckles) Wow!

APPRAISER: Yeah.

GUEST: Wow.

(laughs) That's fantastic.

APPRAISER: I think that, being a unique piece, it might fetch just a little bit more.

GUEST: Oh, okay, tell me.

(laughs) (laughs) APPRAISER: I think, in a retail situation, a necklace like this would be $15,000.

GUEST: Whoa.

(chuckles) Thank you, Grandmother.

(both laugh) GUEST: And if I wanted to insure it, how much would you recommend?

APPRAISER: I would suggest somewhere in that range.

GUEST: Okay.

APPRAISER: And just the gold weight alone is worth about $4,200.

GUEST: Fantastic.

APPRAISER: Gold is so expensive right now.

It's really at an all-time high.

There's jewelry out there that's jewelry that is also art.

GUEST: Uh-huh.

APPRAISER: And that is really what gives this the value.
