GUEST: So this clock originally belonged to my great-great- uncle Arthur. He was born and raised around Albany, New York. He ended up being an attaché after World War II in Japan. He worked in Honolulu, and then ended up working for NATO in Paris, and the family believes that this probably traveled with them all the way around the world, until it finally ended up, they retired back in Albany. And he passed away in about 2002, and this came down to us.

APPRAISER: Wow. So in the business, we call this a crystal regulator. And some people refer to them as a brass and glass clock, for obvious reasons.

GUEST: Okay.

APPRAISER: It does say Tiffany and Company on the dial. And it was retailed by Tiffany. It was not made by Tiffany and Company. I'm not familiar with the maker of this clock, but it was probably made in Paris. Tiffany and Company obviously handled the finest things, and this is certainly one of them. It would have been made circa 1890. It has green onyx all throughout the case. And on the garniture set, which is a remarkable set, as well, it has champlevé, and it's repeated throughout the clock on the columns, on the top of the clock, on the dial. Do you have any idea of the value of this clock at all?

GUEST: We think it's beautiful. Always hoped it was worth maybe $1,000 or $2,000.

APPRAISER: Right. Well, it's worth a little more than that. It's a clock that, if in a retail situation, with these urns, I think you expect to pay $4,000 for a clock like this.

GUEST: That's wonderful. That's really wonderful. Well, we treasure it, and it's going to stay with the family forever.
