GUEST: I brought in a box of jewelry from my grandmother that I got when she passed away back in 2020.

We were in the hospital and she called me in and then she gave this to me before she died.

She told me to put it up in somewhere safe.

So I just put it in my closet, and I kind of forgot about it, until I heard I was going on the ANTIQUES ROADSHOW I wanted to bring it.

APPRAISER: Is that when you told your parents?

GUEST: (chuckles) Yes.

APPRAISER: (laughs) I can't believe you hid it from your mother and father.

What was their reaction when you...?

GUEST: They were really shocked and surprised.

APPRAISER: What do you know about these rings?

GUEST: I don't know much, but when I was younger, she used to paint my nails, and we used to play with them a lot.

And I knew she had, like, a big collection of them.

APPRAISER: Most of the rings in here are real.

All of these rings in the top rows are real gold and real diamonds.

Now, a few of these big ones, like this... ...and this one and this one, the real big diamonds are not.

They're cubic zirconia.

But all the smaller diamonds in the rings are all diamonds.

The only rings that are not gold and that do not have, uh, genuine stones in them are all the rings right here in this bottom row.

GUEST: Okay.

APPRAISER: But over here you have blue topaz.

You have blue sapphire.

This green one is peridot.

You have a real cultured pearl there.

You have amethyst.

Over here you have more peridot, amethyst, citrine.

You know what this one is, right?

GUEST: A ruby, maybe?

APPRAISER: Right, rubies.

And this one?

GUEST: Emeralds?

APPRAISER: That's right.

You have some rings that are a little larger.

Like, this one's amethyst, this one here is synthetic.

It's a big stone-- this one here is synthetic.

This one here is synthetic.

But the ring is still gold.

Ten karat, 14 karat.

There are some rings here that are manufactured in the United States.

There are rings in there that are manufactured in China.

There's a bunch of them, especially the smaller colored stones, that would have been manufactured in Thailand.

I would say overall, they range anywhere from the mid-1960s through the mid-1980s.

GUEST: (chuckling): That's old.

APPRAISER: (chuckling): That's old!

If I add up what's here, it's $15,000 to $25,000.

That's a lot of money-- your grandmother loved jewelry, no doubt about it.

GUEST: Mm-hmm, yes, she has a lot.

APPRAISER: There's more?

More?

GUEST: Yes, I have a lot more at home.

APPRAISER: (laughing): Is it still being hidden?

GUEST: (laughing): Yes.

APPRAISER: Have your mom and dad seen it yet?

GUEST: (chuckling): Not yet.

APPRAISER: (laughs)
