Does this replace a GIA report or an appraisal?

No. It records the appraisal or certificate you already have — a GIA report, an IGI grading, a jeweler's appraisal — and seals it alongside your own photos and the stated metal, stones and carat weight, so the document and the exact piece it described can't be separated later.

You can pay per transfer, or create unlimited transfers on a Solo plan. The same cryptographic guarantee applies either way.

A BILL OF SALE FOR JEWELRY THAT HOLDS UP.

Q: Is a SENT. bill of sale for jewelry a legal document?

It is cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It is independent, tamper-evident evidence you can show a buyer, an insurer, or a payment processor.

Before a ring or a watch changes hands, seal the metal, stones, appraisal or certificate, serial number and condition photos into a cryptographic, tamper-evident record. When a buyer later claims the diamond was swapped or the grade was inflated, the proof of exactly what you sold already exists — dated and unalterable. The proof exists before the dispute can.

// The dispute this prevents

"THE STONE ISN'T WHAT YOU SAID."

High-value jewelry and watches invite the highest-stakes disputes. A buyer claims the diamond was swapped for a lower grade, that the gold is plated, that the watch is a "frankenwatch" with replaced parts, or that the carat weight never matched the appraisal. Months later, the piece they're holding may genuinely differ from the one you sold — and without a sealed record, there's no way to prove which version left your hands.

Without a sealed record

An appraisal on paper that names a piece but not this transaction. Photos with no provable date. A serial number written in a text message. When the claim comes, the document and the item have already drifted apart.

With a SENT. bill of sale

A dated, cryptographically sealed record binding the metal, stones, serial, appraisal and the actual photos together — created before the piece changed hands and impossible to backdate. The piece and its paperwork can't be separated after the fact.

// How it works — three steps

Describe the piece

Enter the buyer and seller, the price, and the jewelry specifics — metal, stones, and the appraisal or certificate reference. The category form surfaces exactly the fields a jewelry sale needs.

Add the evidence

Attach close-up photos, the appraisal or GIA/IGI report, and any serial or hallmark detail. Every file is hashed in your browser before it uploads, so the documents and images are sealed exactly as they are.

Seal & send

The record is sealed with a timestamp and signature, and the buyer gets a link to acknowledge the terms. Their acknowledgment is sealed into the same record. Anyone can verify it — no account required.

// What gets sealed

EVERYTHING THAT SETTLES THE ARGUMENT.

✓Metal & stones — karat, type, carat weight, settings.
✓Appraisal / certificate — GIA, IGI, or a jeweler's report, tied to this record.
✓Serial & hallmarks — for branded pieces and luxury watches.
✓Condition photos — close-ups hashed before upload.
✓Provenance — ownership history and how authenticity is established.
✓Buyer's acknowledgment — sealed with timestamp and IP.

JEWELRY SELLERS ASK

Is this a legal document?

It's cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It's independent, tamper-evident evidence you can show a buyer, an insurer, or a payment processor.

Does it replace a GIA report or an appraisal?

No — it records the appraisal or certificate you already have and seals it alongside your own photos and the stated metal, stones and carat weight, so the document and the exact piece it described can't be separated later.

How does it help if a buyer claims the stone was swapped?

The record is sealed before the piece changes hands and timestamped cryptographically, so it can't be backdated. You have a dated record of the metal, stones, serial and photos that were agreed to at the point of sale.

What does it cost?

Pay per transfer, or create unlimited transfers on a Solo plan — see pricing. The same cryptographic guarantee applies either way.

A VERIFIED BILL OF SALE FOR ANYTHING YOU SELL

Important

SENT. Transfer creates cryptographic proof of a transaction and its agreed terms only. It is not a legal title transfer, not a substitute for any state-required form, and not legal advice.

SEAL THE PIECE. SETTLE IT FOREVER.

Every piece you hand over without a sealed record is a dispute you can't win.
