GUEST: It's, far as I know, a carved sapphire marked Cartier.

APPRAISER: Wow.

GUEST: I got it for a birthday one year, found it at a flea market in our area.

APPRAISER: Okay.

GUEST: My husband got it for me, just fell in love with it. And what did you pay for it? Some hundreds, not more than $1,000. When was that? Ten or so years ago.

APPRAISER: This is a carved sapphire, I would say right around 1920 to 1925.

GUEST: Okay, okay.

APPRAISER: It's a beautiful flower motif on the top. Around early 1900s, Cartier became fascinated with Indian-carved gemstones.

GUEST: Mm-hmm.

APPRAISER: This particular stone, I believe, would be a Ceylon sapphire, it's a lighter-color sapphire.

GUEST: Mm-hmm.

APPRAISER: It's not as saturated as, let's say, a Burma sapphire would be. But Cartier didn't care if it was really that saturated. They just wanted the design. We have platinum shoulders with small diamonds on either side, in that triangular shape. It's also enhanced by black enamel. It goes all the way around the sapphire. It's almost bezel-set, if you will. There's no prongs, and the enamel work is in excellent condition. It's also signed Cartier.

GUEST: Mm-hmm.

APPRAISER: It's stamped inside, and it is a New York piece. The base metal is platinum, and then it's also 14-karat white gold on the bottom.

GUEST: Oh.

APPRAISER: I would say auction estimate would be between $5,000 and $7,000.

GUEST: Oh, my goodness.

APPRAISER: Yeah.

GUEST: Oh, my goodness. Great, thank you.
