APPRAISER: So tell me what you brought us in today.

GUEST: An opal bracelet.

APPRAISER: Opal bracelet? And how did you get it?

GUEST: I inherited it from my great-aunt.

APPRAISER: Where was she from?

GUEST: Chicago.

APPRAISER: Chicago.

GUEST: She had a collection of opals that I inherited.

APPRAISER: Have you opened up the opal?

GUEST: I haven't. I didn't know it opened.

APPRAISER: Yeah, it...

GUEST: It was too small for me to wear...

APPRAISER: It opens... It opens right up here like that.

GUEST: Oh, cool.

APPRAISER: And it exposes the face of the watch underneath there.

GUEST: Awesome.

APPRAISER: It's a very nice watch. It was made by Rolex.

GUEST: Really?

APPRAISER: Yes.

GUEST: Okay.

APPRAISER: Manufactured around 1950.

GUEST: Okay.

APPRAISER: It's all 18-karat gold. The condition of it is really incredible. It shows very little wear at all. The bracelet of that watch has no damage to it. We look at the dial of the watch, and on the face of the watch right there, it's all original, untouched. You have a cabochon opal here, and it's really a nice shape, too. And sometimes opals don't really survive the time, but this one has done very well. I gotta tell you, I've never seen a Rolex with an opal on it. I'm going to take it off for a minute. And you see, there's the Rolex crown right there.

GUEST: Okay.

APPRAISER: On the dial. And on the buckle right here, you've got the Rolex logo, the Rolex crown right here.

GUEST: Okay.

APPRAISER: But look at the iridescence of the opal on that. Isn't that great?

GUEST: Yeah, it's gorgeous.

APPRAISER: Look at the colors. I mean, you've got flashes of green, red. Red is really the most desirable color in opals. So it's a really exceptional opal. There's no crazing on it. It's just really wonderful. Any idea as to the value?

GUEST: I don't know. Maybe $1,500?

APPRAISER: Your watch is very collectible. The market on these are not so much in the United States, it's more in Asia. And your watch today would easily retail for approximately $10,000 to $12,000.

GUEST: Okay. (laughing) Awesome. Wow.

APPRAISER: Insurance, easily a minimum of $15,000 should be put on it for insurance valuation.

GUEST: Okay. Terrific, thank you. That's surprising.

APPRAISER: Good surprise?

GUEST: Very good surprise. That's cool.
