Features — JVal Jewellery Valuation Software

Grade

Assess to convention

Split grading of mounted diamonds — colour and clarity over two grades, higher first, checked as you type.
GIA-correct nomenclature — a specific grade or split grade; "eye clean" and SI3-without-a-report are refused.
Rubover ≠ VVS and other rules flagged at entry and blocked at finalise.
Mounted Diamond Assessment — the full NAJ/IRV worksheet per stone, with plotting to GIA convention.
Pearls, fluorescence and dimensions recorded to the GIA standards built in, with the standard caveats.
Lab-report verification — one-click links to the GIA, IGI, HRD and De Beers report checkers.
Descriptions drafted for you — JVal assembles a full item description from the details you enter; Refine with AI then reads the photographs and adds only what they show, keeping every fact you entered.
Watches too — a built-in catalogue of brands and models, with movement and case details and a link to the maker's reference, so watches are valued as fluently as jewellery.

Price

New-replacement build-up — trade gem prices plus a mount costed from your own manufacturing rates.
Open-market model — auction comparables to hammer, then category-specific build-ups from published methodology.
Every source compared like for like — Gem Guide, RapNet, Rapaport and trade prices brought to a comparable £/ct.
Asian gold — assessed according to IRV guidelines, scaled to the day's gold price.
Manufacturing cost table — your £/g rates by method and fineness, with a monthly currency check.
Purpose-aware presets — insurance, probate, family division, forced sale and more, each on the right basis.
Read from a screenshot — snip a trade price or report and JVal reads the figures straight in, for quicker, easier assessment and pricing.

Prove

Workings kept with the job — every research snip, comparable, grid and calculation stored behind the figure.
Professional Review folder — set anonymised examples aside as you go, ready for institute submission.
Issued documents are never edited — amendments create a numbered revision; the original is preserved.
Pre-flight check — every open issue and advisory listed in one place before you commit.
Rate and evidence provenance — live daily exchange rates and bullion prices, with the figures used recorded per valuation.
Page integrity — every printed page footered with purpose, client and "page x of y".

The full pack — cover page, transmittal letter, schedule, Notes to the Schedule and appendices, produced as a print-ready PDF.
On your brand — logo, letterhead and choice of document themes, bound-edge margins for presentation.
Signed throughout — letter and schedule both carry the valuer's signature; printing is gated until one is on file.
Riders and standard comments — an editable library, inserted per item or into the letter.
Certificate of Sale — a retail sale document for the counter, in the same house style, carrying an e-signature.
One-click pack — build the whole valuation into a single PDF, then print or email it directly from the app.
Password-protected as standard — every valuation PDF is locked with a password built from your client's own details, so only your client can open what you send. Opt out per valuation whenever open access suits better.

Run the practice

Client database — add, search, merge and import, with valuations and balances per client.
Invoicing & outstanding — raise, mark paid, and see what's owed at a glance on the dashboard.
Email templates — enquiry replies with your terms and fees, appointment confirmations, reminders — auto-filled.
Address finder — type a postcode, pick the exact address (with a supported data provider).
Multiple valuers — a signing roster with each valuer's credentials and memberships.
Revaluation reminders — flag valuations older than your chosen interval.

Peace of mind

Guidelines it follows, in the open — a Standards page summarising every rule the app checks or enforces.
Your data stays on your computer — clients, valuations and photographs are never uploaded to a JVal database, and there are no analytics. The AI features send only what you choose to send them.
Client documents protected in transit — valuation PDFs leave the app password-protected as standard, a real answer to the GDPR question of emailing personal data.
Guarded actions — anything that can't be undone is double-confirmed first.
Backups by design — a dated automatic backup every time the app closes, a one-click manual backup, and a restore that puts everything back including the photographs.

Help

JVal AI Assist — built into the software and into this website. Describe what is happening, paste a screenshot if that is easier, and it answers in plain steps rather than jargon.
It knows the whole manual — not a search box and not a list of articles, but an assistant that has read every page and answers the question you actually asked.
There at any hour — every valuer ends up working alone at some point, usually at the worst possible moment.
Free on every plan — including the free one, and including a subscription that has lapsed. Support is not something to ration.
One button to a person — if Assist cannot sort it, the whole conversation goes to Simon, so you never have to type it all out again.
