Jade Appraisal Checklist: Photos, Light Tests, Dimensions, and Provenance

Start with an evidence packet, not a guess

A jade-labeled bangle, pendant, bead strand, or carving can be exciting. It can also be difficult to describe from one green, glossy phone photo. A useful first read starts with a repeatable record: neutral photos, safe light observations, exact dimensions, condition notes, and documents that show where the object came from.

The word jade is not a complete identification. It can refer to jadeite or nephrite, and other materials can be sold under jade-like names. Color, translucency, carving quality, treatment risk, and material type all matter more than the label alone. This checklist helps a reviewer see those questions clearly; it does not settle them by itself.

Photograph the object in a fixed 12-shot sequence

Good appraisal photos are not studio glamour shots. They are comparable records. Use the same background, camera distance, and orientation so color changes, asymmetry, repairs, and construction details do not disappear between frames.

Set up a five-minute photo station

1. Wipe the surface only with a soft cloth. If cleaning is necessary, use conservative warm soapy water and dry it carefully; avoid ultrasonic or steam cleaning when treatment status is unknown.
2. Place the object on matte white, light gray, and dark gray paper. The three backgrounds help show pale edges and dark silhouettes without adding a color cast.
3. Stand near a bright window out of direct sun. Turn off warm room lights. Do not use portrait mode, beauty filters, HDR effects, or automatic color enhancement.
4. Use the rear camera at its normal focal length. Brace the phone or use a small tripod. Tap the object to focus, then reduce exposure if polished highlights turn white.
5. Keep the original image files. Cropped copies are useful for sharing, but metadata and surrounding context can help a reviewer audit the packet.

Take these 12 photographs in order

Name the files 01-front through 12-context. That small step prevents a reviewer from mistaking a backlit detail for the normal-color view.

Add the shots your object type needs

Use light to record color and translucency safely

Light changes what jade looks like. That makes controlled lighting useful for documentation and dangerous as a shortcut. A bright green edge, cloudy patch, dark band, or fluorescent response is something to record. It is not a home authentication result.

Take a neutral color view first

Photograph the object under indirect daylight or a high-color-rendering daylight lamp. Include a plain white card in the first frame, then remove it for the close-up. Record the light source and whether the phone altered the image. The goal is not to make the green look richer; it is to give the reviewer a baseline.

Note the dominant color, secondary colors, and distribution in ordinary words: “pale gray-green with two darker patches” is more useful than “imperial.” Also note whether the pattern looks even, mottled, veined, spotted, or concentrated near an edge.

Make one diffused transmitted-light view

Place a cool, diffused white light behind the object without touching it. A phone flashlight can work if you cover it with a clean white paper diffuser and keep heat away. Photograph the whole object, then one close-up of the thinnest area. Record where light passes through, where it stops, and whether internal bands or cloudy zones become easier to see.

Thickness controls this result. An opaque center and glowing edge can simply reflect different section depths. That is why the transmitted-light photo must travel with a profile photo and thickness measurement.

Treat UV as optional screening, never a verdict

If you already own a proper gem-testing UV lamp, record its wavelength, the room conditions, the response color, and whether the response is even or localized. Wear UV-protective goggles, avoid skin exposure, and never look into the beam. Skip the test entirely for an object you cannot illuminate safely.

Fluorescence alone cannot determine material, origin, age, or treatment. GIA describes UV as a screening observation and uses broader laboratory testing for conclusive identification. A “no reaction” result is not a certificate, and a bright reaction is not proof of dye or resin.

Skip tests that can damage the object or mislead you

• No scratch test: it can permanently mark jade, a lookalike, a coating, or a mount.
• No flame or hot needle: heat can damage jade, treatments, adhesives, cord, or metalwork.
• No acid, solvent, bleach, or acetone: treatment status is unknown and the surface may be vulnerable.
• No drop or impact test: toughness does not make a carved edge, old repair, or mounted jewel indestructible.
• No sound verdict: a ring tone depends on shape, thickness, suspension, fractures, mounts, and handling.
• No “cold to the touch” verdict: temperature response varies with environment, size, and comparison material.

Measure dimensions that another person can compare

“About two inches” is not enough for a useful comparison. Record in millimeters, use a digital caliper gently if you have one, and never clamp across a fragile edge. Photograph the tool reading while the object is in position.

Use three axes and name them

For a carving, record height × width × depth. For a pendant, record the jade element separately from the bail and chain. For a ring, record the stone or carved element, total ring size, and mount height. For a flat plaque, record maximum height × maximum width × thickness at both the thinnest and thickest safe points.

Measure bangles and beads consistently

• Bangle: inside diameter across the opening, outside diameter, wall width, wall thickness, and total weight.
• Beads: strand length, bead count, smallest and largest bead diameter, representative bead diameter, clasp length, and total weight.
• Matched pair: measure and weigh each item separately. Near-matches can differ in thickness, color distribution, or repair history.

Do not subtract an estimated mount weight. State exactly what went on the scale: “complete pendant with 14K-marked mount and chain, 18.42 g” is auditable; “jade weighs around 15 g” is not.

Turn condition into a simple map

Draw an outline or print the front and back photos. Number each chip, fracture, abrasion, stain, repair, loose fitting, and polish difference. Match those numbers to close-up filenames. Condition changes the comparison set quickly, and the map keeps a small edge nick from being confused with a through-fracture.

Build provenance another person can audit

Provenance is the documented chain of ownership and custody. A family story is a lead. A dated receipt, old photograph, inventory, insurance schedule, export document, exhibition label, repair invoice, or correspondence can corroborate part of that story.

Write the ownership timeline before scanning papers

Keep uncertainty visible. “Reportedly purchased in Hong Kong before 1975; no receipt located” is more credible than converting the story into an exact date. Do not assign a dynasty, mine, workshop, or previous owner unless a record supports it.

Scan documents with their context

• Photograph the front and back of every label, card, envelope, tag, or certificate.
• Capture the whole document before close-ups of stamps, signatures, numbers, or photographs.
• Keep edges, folds, holes, handwriting, and attached notes visible.
• Record who supplied the document and when it was found.
• Do not crop a seller name, date, amount, laboratory number, or disclaimer.

A certificate is evidence about what the issuing party reported. It is not automatically current, authentic, or sufficient for today’s decision. Save it, photograph it, and let the reviewer assess it with the object.

Keep history and market value in separate columns

An old ownership record can improve confidence in the timeline without proving material or treatment. A laboratory report can identify material or disclose detected treatment without proving an inherited family story. An appraisal can address a specified value question without establishing archaeological or cultural origin. Strong packets keep these jobs separate.

Assemble one submission packet

Create a folder named jade-object-owner-year. Put original photos in 01-photos, measurements and condition notes in 02-object-record, provenance documents in 03-provenance, and any prior reports in 04-reports. Do not overwrite the originals when you crop or annotate a copy.

Run a 60-second quality check

• Can you see the full object before any detail crop?
• Are front, back, profile, base, scale, and condition views present?
• Do the written dimensions match the ruler or caliper photographs?
• Are normal-light and backlit photographs clearly labeled?
• Are owner stories separated from documents?
• Did you state what the weight includes?
• Did you preserve original files?
• Did you say what decision the appraisal needs to support?

Compare market evidence only after the object record is complete

Auction results are useful when the lot and your object share relevant characteristics. For jade, the comparison can change with material identification, treatment disclosure, color, translucency, texture, workmanship, object type, dimensions, condition, mount, and provenance. A broad label match is not enough.

The selected results below are exact jadeite bangle records from the curated evidence file. They show why the packet needs inside diameter, wall thickness, weight, color views, mount details, and treatment documentation. They do not authenticate an owner’s object or predict a price by visual resemblance alone.

Know what this checklist cannot prove

Phone photographs can support an initial category and market read. They usually cannot prove whether a green object is jadeite, nephrite, another mineral, glass, or a composite. They cannot reliably establish treatment status, geographic origin, age, or a named workshop.

That boundary is practical, not pessimistic. If the object appears ordinary and your goal is curiosity, the packet may be enough to stop. If the object appears commercially significant or the decision requires documentation, a qualified gemological laboratory may be needed for material and treatment questions, while an appraiser addresses the relevant value and market.

Jade appraisal checklist FAQ

How many photos should I send for a jade appraisal?

Start with the 12-shot sequence, then add object-specific views. A bangle usually needs interior, outer edge, profile, and flat-spot details. A carving needs every face, base, undercuts, and the stand separately. Sharp, labeled coverage matters more than a high photo count.

Can a flashlight identify real jade?

No. A diffused backlight can document translucency, internal bands, cloudy zones, and thickness differences. Those observations help a reviewer ask better questions, but they do not identify the material or prove treatment status.

Does UV fluorescence prove jade is treated?

No. UV can be a screening observation when used safely and recorded correctly. A reaction—or no reaction—does not by itself prove material, origin, age, dye, bleaching, or polymer impregnation. Conclusive questions can require laboratory instrumentation.

Should I do a scratch or hot-needle test before appraisal?

No. Both can damage the object and neither produces an appraisal-grade conclusion. Keep the object intact, record what you can see, and let a qualified professional choose non-destructive testing appropriate to the question.

How do I measure a jade bangle?

Record inside diameter across the opening, outside diameter, wall width, wall thickness, and total weight. Use millimeters. Photograph each measurement and do not force a caliper across a chipped or fragile edge.

What counts as provenance for jade?

Dated receipts, old photographs, inventories, insurance schedules, correspondence, exhibition labels, repair invoices, export records, and prior reports can support parts of an ownership timeline. A family story is still worth recording, but label it as reported until a document corroborates it.

Do I need an online appraisal or a gem laboratory?

They answer different questions. A photo-based first read can assess visible evidence and market direction. A laboratory can address material and detected treatment with testing. A written appraisal addresses a defined value question. Start with the decision you need to make, then pay only for the evidence that decision requires.
