1938 Granat Brothers Jade & Diamond Ring

Value (2011) | $4,000 Auction$6,000 Auction

This is a family piece. The stone was originally purchased at the World's Fair in San Francisco Bay at Treasure Island. And then it was set as a ring by Granat Brothers in San Francisco.

Well, it's a really beautiful piece, and it's interesting that the stone was purchased separately from the setting. And that's what makes it a little bit more interesting than just the average jade stone. It's been set by Granat Brothers, who was a really reputable jeweler.

That was the jeweler, quite frankly.

Yes, exactly. The setting is beautiful. It's a platinum and diamond setting, and the jade stone you had brought in and you picked the setting, you said. How did you pick it?

Oh, my parents were advised by their designer and they wanted something complementary, and I guess in those days, Art Deco was what was new.

That's beautiful. Well, in today's market, what's difficult is to find an antique setting that would complement a stone of this nature. And what's nice is we can date the stone to at least, you said 1938, correct?


Which means that more likely than not, there's no treatment to the stone whatsoever. It's usually an impregnation of color, or it's been dyed. It's normally just an enhancement of a green that's already there. And there are a few folks in the U.S. who are able to determine whether or not a jade stone has been treated. But we normally say prior to the 1950s, 1960s, there really isn't much of a chance that it's had those treatments done and it's probably all natural. It's a nice large piece, it's nice and flat. Really the only thing the ring needs is just a quick buff to the top of it. Do you wear it much right now?

Not at all.

Oh, you should. I like that you also have the original box. While it doesn't add a lot of value, it's a fun thing to have. I also love, and you have right here, a picture of you as a child at the World's Fair in San Francisco. So sweet.

Oh, thank you.

Nice little thing to add to the provenance. Do you have any idea how much your parents might have paid for it?

Not a clue. I know a journeyman carpenter was working for 35 cents an hour in those days, so...

Okay. Jade is very, very popular right now. And the greener it is, the more value it has. At auction today, and auction is a fair market value, we would probably use an estimate of about $4,000 to $6,000.

Oh, my.

Executive producer Marsha Bemko shares her tips for getting the most out of ANTIQUES ROADSHOW.

Value can change: The value of an item is dependent upon many things, including the condition of the object itself, trends in the market for that kind of object, and the location where the item will be sold. These are just some of the reasons why the answer to the question "What's it worth?" is so often "It depends."

Note the date: Take note of the date the appraisal was recorded. This information appears in the upper left corner of the page, with the label "Appraised On." Values change over time according to market forces, so the current value of the item could be higher, lower, or the same as when our expert first appraised it.

Context is key: Listen carefully. Most of our experts will give appraisal values in context. For example, you'll often hear them say what an item is worth "at auction," or "retail," or "for insurance purposes" (replacement value). Retail prices are different from wholesale prices. Often an auctioneer will talk about what she knows best: the auction market. A shop owner will usually talk about what he knows best: the retail price he'd place on the object in his shop. And though there are no hard and fast rules, an object's auction price can often be half its retail value; yet for other objects, an auction price could be higher than retail. As a rule, however, retail and insurance/replacement values are about the same.

Verbal approximations: The values given by the experts on ANTIQUES ROADSHOW are considered "verbal approximations of value." Technically, an "appraisal" is a legal document, generally for insurance purposes, written by a qualified expert and paid for by the owner of the item. An appraisal usually involves an extensive amount of research to establish authenticity, provenance, composition, method of construction, and other important attributes of a particular object.

Opinion of value: As with all appraisals, the verbal approximations of value given at ROADSHOW events are our experts' opinions formed from their knowledge of antiques and collectibles, market trends, and other factors. Although our valuations are based on research and experience, opinions can, and sometimes do, vary among experts.

Appraiser affiliations: Finally, the affiliation of the appraiser may have changed since the appraisal was recorded.
