What Is Estate Jewelry?

Estate jewelry is previously owned jewelry. That is the whole definition, and it is broader than most people expect. The word "estate" does not tell you how old a piece is, what it is made of or who made it. It says only that the piece has had an owner before you, whether that was a family that inherited it, a collector who sold it or a dealer who bought it at auction. A brooch made in 1850, a cocktail ring made in 1945 and a diamond bracelet bought in 2015 and sold last year are all estate jewelry. What changes the value, the care and the buying risks is the era, the maker, the materials and the condition, and this guide explains how to read each of those.

Estate, antique, vintage: how the words are used

Dealers use three overlapping words, and the confusion between them causes most of the misunderstandings in this market.

• Estate means previously owned. It is a statement about ownership, not age.
• Antique conventionally means 100 years old or more. Antique Jewelry University, a reference run by a dealer, puts antique pieces at 100 years or more, and the general convention for antiques as a category is the same.
• Vintage is looser. The same reference describes vintage items as roughly 20 to 100 years old, meaning too young to be antique but old enough to be a period piece. Some sellers use narrower or wider windows, so the word is a clue rather than a guarantee.

So an estate piece can be antique, vintage or neither. The reverse is not always true, because a brand-new antique reproduction is not an estate piece, and a piece sold by its maker for the first time is "new" however old the design.

When you see a listing, read the age words as a seller's description. The most reliable way to confirm age is to match the piece's style, materials and construction to the period it claims, which is what the sections below help with.

The main jewelry eras

Collectors sort older jewelry into named periods. The dates overlap at the edges, because styles do not change on a single day, and sources differ by a few years. The ones below follow Antique Jewelry University and, for the reigns, standard history.

A little about each, because the period affects both the look and the value.

### Georgian, 1714 to 1837

Georgian jewelry was made by hand, which is why it can look irregular and warm. Gold was usually 18 karat or higher, silver was the only available white metal and was used to set diamonds, and pinchbeck, a copper and zinc alloy, stood in for gold. Gemstones were often backed with foil to enhance their color.

### Victorian, 1837 to 1901

Victorian jewelry is the largest body of antique jewelry because Queen Victoria reigned from 1837 until 1901. Collectors split it into three stages. The Romantic period, from 1837 to 1860, was sentimental. The Grand period, from 1860 to 1885, was more elaborate and includes much of the dark mourning jewelry made after Prince Albert's death in 1861. The Aesthetic period, from 1885 to 1901, was a reaction against earlier fashions. Common materials include gold, enamel, garnets, turquoise, pearls and jet.

### Art Nouveau, about 1890 to 1910

Art Nouveau reached a peak at the 1900 Paris Exposition. Its jewelry used plants, insects and flowing lines, along with techniques such as plique-a-jour enamel and horn. René Lalique is the best-known designer. These pieces are often valued for design and craftsmanship more than for the size of the stones.

### Edwardian, 1901 to 1910

The Edwardian era runs through King Edward VII's reign, and the jewelry style continues a few years beyond it. It is the era of platinum. The invention of the oxyacetylene torch in 1903, which could reach the temperatures needed to work platinum, allowed jewelry to be made entirely from the metal, so designs became light and lacy, with bows, ribbons, garlands and millegrain borders.

### Art Deco, 1920s and 1930s

Art Deco jewelry is geometric and graphic. The style came out of the 1925 Paris Exposition and flourished through the 1930s, and it used platinum, new gemstone cuts, invisible settings, and cultured pearls, which became a defining jewel of the 1920s.

### Retro, late 1930s through the 1940s

During the war, platinum was reserved for the war effort, so Retro jewelry was made mostly in gold, in yellow, rose and green colors. Jewelers used larger, more available stones such as citrine, amethyst, topaz and aquamarine, and the pieces are big, dimensional and playful.

### What came after

Jewelry made from the 1950s onward is still estate jewelry if it was previously owned, and the better pieces from the mid-century and later decades are collected under the name of the maker or the style. A 1980s piece from a major house, for example, is a perfectly good estate purchase. It is vintage by the 20-to-100-year rule, and it is not antique.

Hallmarks and maker's marks

Marks on the metal are the first thing an experienced buyer looks for. A hallmark is an official mark struck on a precious metal item to state its purity, and in some countries it also shows where and when the piece was assayed.

The United States works differently from the United Kingdom. The US has no official hallmarking scheme, and instead relies on the National Gold and Silver Stamping Act of 1906, amended in 1961, which requires that articles of gold or silver marked for quality also carry the maker's trademark or full name. A US karat mark therefore tells you the maker's claim about purity, with the maker's mark identifying who made that claim. In the UK, assay offices test and mark items independently, and the marks can include an assay office symbol, a fineness mark and a date letter that dates the piece.

A few practical points:

• Look with a loupe. Marks are small, and the usual places are the inside of a ring shank, the back of a brooch, the clasp of a necklace and the edge of a bracelet.
• A missing mark is not proof of fakery. Older pieces, repaired pieces and resized rings can lose marks, and some period pieces were never marked. Antique Jewelry University notes that pieces which have been fundamentally altered, such as resized rings or repaired clasps, may have lost identifying marks.
• A mark is a claim, not a certificate. Fantasy and imitative marks exist, and Antique Jewelry University lists "pseudo hallmarks" among the topics it covers. Treat a mark as one piece of evidence and confirm the metal separately. Our guide "How to Tell If Gold Is Real" covers practical tests, and "Karat vs Carat: Two Different Words" explains the units behind a gold mark and a stone weight.

How estate jewelry is priced

There is no single pricing formula, and it helps to understand the layers.

Materials. Gold and platinum have a metal value, and gemstones have a value based on size, quality and type. Our guide "Jewelry Appraisal: What It Is and What It Costs" explains why one piece can have several legitimate values depending on the purpose, including replacement value for insurance and a lower resale value.

Era and style. Some periods are scarcer and more sought after than others. Some periods are scarcer than others, and the demand for a style changes over time.

Maker and signature. A piece signed by a recognized house can be worth considerably more than an identical unsigned piece, because the name carries provenance and design significance. A dealer writing for 1stDibs names houses such as Van Cleef & Arpels and Cartier, and the designer Suzanne Belperron, as examples of signed work that draws special attention.

Condition and originality. Original stones, original finishes and unaltered construction are valued. Repairs, replaced stones and later additions reduce value on collectible pieces, and a good dealer will tell you what has been done.

Scarcity. Because the supply of older jewelry is finite, desirable pieces can be hard to replace.

Where you buy. A retail dealer prices to cover overhead and risk, an auction price reflects what bidders will pay on the day, and a pawn or buyer of scrap gold prices closer to metal value. The same ring can be priced very differently in each setting, and none of them is wrong.

Because of these layers, ask what you are being quoted. A figure based on retail replacement is not a figure you will receive if you sell.

Buying cautions

Estate jewelry is a rewarding category and a risky one for buyers who do not ask questions.

1. Ask for the metal and the stones in writing. The listing should say the karat or purity, the type of stone and whether it is natural, lab-grown, synthetic or treated.
2. Ask whether stones and parts are original. Replaced stones, later clasps and added elements are common on old pieces, and a seller can say which.
3. Ask about repairs and alterations. Resizing, re-tipping and re-plating all change a piece.
4. Be careful with era claims. Words like "Victorian" and "Art Deco" are used loosely, including for later pieces made in those styles. Style revivals exist, and a reproduction made decades ago can itself be vintage.
5. Check the return policy. Because estate pieces are one of a kind, know before you buy what happens if the piece is not as described.
6. Match the price to the facts. An unusually low price on a signed piece is a reason to ask more questions, not to hurry.
7. Get an independent opinion on expensive pieces. An independent gemologist or appraiser can confirm stones and metal for a fee.

Seeing a piece before you bid

An estate piece is a single object, so details matter: how a stone sits, whether an enamel surface is intact, how heavy a chain feels, what a hallmark looks like under magnification. In a live sale you can see the piece on camera, ask the seller to turn it, show the back and the marks, and ask your questions before you bid.

On ShopBidz, NYC Watches & Diamonds, operated by NYC Watches LLC in New York, sells luxury watches, jewelry and bags. GG Luxury Revival, operated by GG Luxury Revival LLC on Long Island, New York, sells luxury items and jewelry. DeJesusTreasures, from Wallingford, Connecticut, sells handbags, jewelry and accessories. All three are sellers you can watch live when you are looking at jewelry, and the questions in the cautions list above are the right ones to put to any of them.

Bottom line

Estate jewelry means previously owned jewelry, and it can be antique (100 years or more), vintage (roughly 20 to 100 years) or recent. The era tells you what to expect: Georgian pieces are hand-fabricated, Victorian pieces span 1837 to 1901 and include the mourning styles, Edwardian pieces from 1901 to 1910 are the platinum era, Art Deco pieces are geometric, and Retro pieces from the late 1930s and 1940s are bold gold. Marks help but are not proof, because US karat marks are the maker's claim and older or repaired pieces can lose their marks. Price depends on materials, era, maker, condition, scarcity and the channel you buy through, so ask what a figure means before you rely on it. Ask about originality and repairs, get the metal and stones described in writing, and use a live sale to look closely before you bid.
