Jewelry is one of the hardest categories to catalog well, because identity lives in details that are easy to overlook and hard to recover once a piece leaves your hands. A ring is not just a ring: it is a specific metal at a specific fineness, set with stones of a particular cut, color, and clarity, made by a particular hand in a particular decade. Two pieces that look identical across a table can differ by an order of magnitude in value depending on whether the gold is 14k or 18k, whether the center stone is a natural or lab-grown diamond, whether the maker's mark reads Cartier or an unsigned French workshop, and whether the form is genuine Art Deco or a 1980s revival. The fields that matter are precise: metal type and karat or millesimal fineness, total carat weight, individual stone specs (cut, color, clarity, carat), setting style, hallmarks and assay marks, maker or signature, country of origin, period or style, dimensions and gross weight in grams, and the condition of prongs, clasps, and original finish. Costume and vintage pieces add their own vocabulary: rhinestone versus paste, japanned metal, foiled-back stones, fur clips and dress clips, and signatures like Trifari, Miriam Haskell, or Schiaparelli that turn a $20 brooch into a sought-after object.
The Hoard is where that record lives. It is a collector-first, object-first vault built for the way jewelry people actually think: piece by piece, mark by mark, story by story. It is not a marketplace and not a consignment service. Your jewelry stays exactly where it is, in your safe, your bank box, or on your hand, and the vault holds a private, structured record of what each piece is and what you know about it. You assign every entry a primary category, such as fine, costume, signed, or vintage, then layer secondary tags for metal, era, gemstone, maker, or whatever distinctions you care about, so a 1925 platinum filigree ring and a signed Haskell parure can both live in one collection without losing their separate identities.
What to record for every piece
Start with the body of the piece itself. Capture the metal and its fineness exactly: yellow, white, or rose gold at 9k, 14k, or 18k; platinum, usually marked 950 or PT950; sterling silver at 925; or base metal and plating for costume work. Record the gross weight in grams, because metal weight is both a value floor and a fingerprint, and note dimensions such as ring size, chain length, or brooch span. Then transcribe every mark you can find under a loupe: karat stamps, millesimal numbers, assay or hallmark stamps, country-of-origin marks, patent numbers, and maker's marks or signatures. On signed pieces these marks are the whole ballgame, so record exactly what is stamped and where it sits, since placement and font often separate an authentic mark from a later fake.
Document the stones with the same discipline. For each significant gem, note the cut (round brilliant, old European, old mine, rose, emerald, marquise, cabochon), the carat weight if known, and for diamonds the color and clarity grade. State whether stones are natural, treated, synthetic, or simulant, and flag anything you only suspect rather than know. Capture the setting style as well, since prong, bezel, pavé, channel, and millegrain settings carry both period clues and condition risk. For costume and vintage pieces, the analogous details are stone type (rhinestone, paste, glass, foiled-back), construction (riveted, glued, prong-set), and findings such as trombone clasps, fur clips, or screw-back earrings that help date a piece.
Finally, record what cannot be re-derived later: where and when you acquired the piece, what you paid, any prior owners or family history, repairs and resizings, and the current condition of wear points like prongs, clasps, hinges, and the original finish. A note that says "left rear prong retipped 2019, original box and Cartier certificate present" is the kind of detail that protects value and settles questions years down the line.
Identifying a piece by photo with Gideon
Jewelry is rarely labeled in any human-readable way, which makes a good starting point invaluable. The Hoard's photo scanner, Gideon, lets you photograph a piece and have it identified against a reference catalog so you can confirm rather than build every entry from a blank field. Shoot the front of the piece in even, diffuse light, then capture the back and any marks, since the underside and the clasp usually tell more of the truth than the face does.
Gideon proposes a likely match and pre-fills what it can infer about form, style, and category, and you confirm or correct it. This is the right division of labor for jewelry, where a machine is good at narrowing the field from a photo but the collector's loupe and judgment make the final call on metal, marks, and stones. Treat Gideon's suggestion as a strong first draft of the entry, then verify the karat stamp, read the maker's mark yourself, and adjust the stone details to match what you actually see.
Confirmed entries become part of your vault's structured record, and because a brand-co-authored registry helps confirm item identity, signed and maker-marked pieces can be anchored to a verified reference rather than to your best guess. That distinction matters most exactly where jewelry value concentrates: in the signature, the hallmark, and the named house behind the piece.
Organizing a collection that keeps growing
Jewelry collections sprawl in more directions than most categories, because people collect across metals, eras, makers, and reasons at once. The vault's structure is built for that. Every piece gets one primary category, so you can keep fine, costume, signed, and vintage cleanly separated, and then any number of secondary tags for the cross-cutting attributes you actually search by: 18k, platinum, Art Deco, Retro, mid-century, signed Trifari, Georgian paste, emeralds, or estate purchase. The result is that you can pull up every Art Deco platinum piece, or every signed brooch, or everything inherited from one relative, without reorganizing anything.
Tagging by era and maker pays off as a collection matures into a real archive. Vintage and antique jewelry sorts naturally into periods such as Georgian, Victorian, Edwardian, Art Nouveau, Art Deco, Retro, and mid-century modern, and tagging consistently lets you see the shape of your own collecting, including the gaps. Signed-jewelry collectors can build a maker's index across costume and fine alike, grouping every Haskell, Trifari, Schreiner, or Van Cleef piece in one view.
Keep the record honest as pieces change. When you resize a ring, replace a clasp, reset a stone, or send something out for restoration, update the entry so condition history travels with the object. A vault that tracks not just what a piece is but what has happened to it is far more useful than a static list, and it is the version of your collection you will be glad to have if it ever needs to be valued, divided, or passed on.
Appraisals, provenance, and authentication
For fine jewelry, the documents matter almost as much as the metal. Attach the details of any independent appraisal, gemological report, or lab certificate to the entry, and record the grading lab, report number, and date so the paperwork stays bound to the piece it describes. A loose GIA report in a drawer is worth far less than one tied to the exact ring it grades, and an entry that captures the report number lets you confirm at a glance which certificate belongs to which stone.
Provenance is the other half of value, especially for signed, period, and estate jewelry. Record original boxes, papers, receipts, and any chain of ownership, because a piece with its original maker's box and purchase documentation reads differently from an identical loose piece. The vault gives provenance a permanent home, so the story of where a piece came from does not live only in your memory or scatter across emails and shoeboxes.
All of this is a private record, kept for your own knowledge and protection rather than to advertise anything. The Hoard is non-custodial: your jewelry never leaves your possession, and cataloging a piece does not list it, price it, or offer it to anyone. The vault simply makes you the authoritative source on your own collection, which is exactly what you want when an insurer, an appraiser, or an heir comes asking.
Frequently asked
What is the best way to catalog a jewelry collection?
The best way to catalog a jewelry collection is to record each piece by its identifying attributes rather than by a single photo or label. For every item, capture the metal and fineness (such as 14k, 18k, platinum 950, or sterling 925), gross weight in grams, dimensions, and every hallmark, karat stamp, and maker's mark you can read under a loupe. Document each significant stone by cut, carat, color, clarity, and whether it is natural, treated, or synthetic, and note the setting style and condition of prongs and clasps. Then add what cannot be re-derived later: where and when you acquired it, what you paid, prior ownership, and any repairs. The Hoard is built for exactly this. You photograph a piece, identify it with the Gideon scanner, confirm the details, and store everything in a private, structured vault organized by primary category and secondary tags.
Is The Hoard free for jewelry collectors?
Yes. The Hoard has a free tier that lets jewelry collectors start cataloging pieces, photographing them with the Gideon scanner, and organizing a vault by category and tags. There is also Collector Pro, which is available monthly, annually, or as a $179 lifetime unlock while founding seats remain. Free members can keep cataloging; Pro unlocks the full collector toolset.
How does The Hoard identify a piece of jewelry from a photo?
The Hoard identifies jewelry through its photo scanner, Gideon. You photograph the piece, ideally the front, the back, and any hallmarks or maker's marks, and Gideon compares the images against a reference catalog to propose a likely match. It pre-fills what it can infer about the form, style, and category, and you confirm or correct the result, verifying the karat stamp, reading the maker's mark yourself, and adjusting the stone details to match what you see. A brand-co-authored registry helps confirm identity for signed and maker-marked pieces, so the final entry is anchored to a verified reference rather than a guess.
Does cataloging jewelry on The Hoard list my items for sale?
No. The Hoard is not a marketplace, and cataloging a piece never lists it, prices it, or offers it to anyone. The Hoard is non-custodial, which means your jewelry stays physically with you, in your safe, your bank box, or on your hand. A vault entry is a private record of what you own and what you know about it, not storage, escrow, or a sales listing. The catalog exists for your own knowledge, insurance, and provenance, and you control who, if anyone, ever sees it.
How do I tell signed and vintage jewelry apart when cataloging?
Signed jewelry carries a maker's mark or signature, such as Trifari, Miriam Haskell, Cartier, or Van Cleef & Arpels, and that signature is often the single most important field to record because it can transform an ordinary-looking piece into a sought-after one. Vintage jewelry is defined by age and period rather than by a name, sorting into eras like Georgian, Victorian, Edwardian, Art Nouveau, Art Deco, Retro, and mid-century, which you read from construction clues such as cut of stones, type of findings, clasps, and metalwork. In The Hoard you give each piece a primary category like signed or vintage and then add secondary tags for maker, era, metal, and gemstone, so a piece can be both signed and vintage and still be findable under either lens.
