GUEST: It was a gift to me and my husband from my mother-in-law. She worked for a very prominent family, and they lived in Connecticut. And it was given to her in the '40s. I believe it was made by Tiffany.

APPRAISER: That's right, by Tiffany Studios, which was founded by Louis Comfort Tiffany at the turn of the century. And he was the son of the famous silversmith Charles Tiffany, who started the big shop in New York. What we have here is part of a desk set. It's a gilt bronze piece. And this would have belonged to a larger set that would have included blotter ends, a little stamp box... I think a full set could have had about 15 different pieces in it. It is a hinged box, which is a little more substantial than several of the pieces that you would find in the desk set. What's most unusual about it is the pattern and the fact that it has the glass stones which are meant to look as if they are cabochon sapphires and emeralds. At auction, it would bring about $1,000 to $1,500.

GUEST: Wow, that's great.

APPRAISER: Yeah.
