Almost every serious estate piece is now bought sight-unseen, from a photograph. That works — but only if you know what to ask before you pay. Here are the questions, the red flags, and how the four buying channels actually compare.
People imagine the danger of buying jewelry online as an outright scam — you pay, nothing arrives. That happens, but it is rare and easy to avoid. The far more common outcome is that something does arrive, and it is not what you thought you bought. The ring is 10k, not 18k. The centre stone is 1.40 ct of heavily included material rather than the 1.50 ct the listing implied. The emerald is oiled and nobody mentioned it. The Cartier is “in the Cartier style”.
None of those are lies you can point at. They are the space between a vague description and what a gemologist would have written. That is why the most useful habit when buying estate jewelry online is not hunting for reviews — it is reading the description like a contract and asking, in writing, about everything it leaves out.
Estate jewelry is second-hand by definition, and that is exactly why it is good value — the original retail markup is gone. If you are not sure what the word covers, start with what estate jewelry actually means. This page is about the buying itself.
Ask any seller, anywhere. A real dealer answers all five without hesitating.
Not “we inspect everything” — a name, and what that person is trained in. A listing written by whoever photographed the piece is a guess with a price attached.
Metal purity from a hallmark or a test, carat weight measured or estimated, a colour and clarity range, and any treatment disclosed. “Approximately” is fine. Silence is not.
A written gemological description at minimum. For diamonds, a lab report if one exists. For watches, box and papers if they exist — and a clear statement if they do not.
Carrier, signature requirement, and the name of the policy. “We ship insured” without a carrier and a policy behind it is a sentence, not coverage.
Get the answer in writing, before you pay, from any seller. This is the question resellers avoid and dealers answer plainly, and it is the one that protects you.
A store name with no person, no phone number and no address you can look up is a shell. You should be able to reach a human on the phone before you send money.
| Red flag | What it usually means |
|---|---|
| No metal purity stated | Nobody tested it. Gold-filled and gold-plated pieces are routinely listed as “gold”. A hallmark should be quoted — see hallmarks explained. |
| “Cartier style”, “attributed to”, “unsigned” | It is not that house. A genuine signed piece is signed, and the seller will photograph the signature. See signed & designer jewelry. |
| Price far below the metal value alone | Either the metal is not what it says, or the stones are synthetic, or the piece does not exist. Gold has a floor, and nobody sells below it by accident. |
| Fine ruby or emerald called “untreated” with no lab report | Untreated fine colour is rare and expensive to prove. Claimed without a report, assume treated. See colored gemstones. |
| Stock photos, or the same photo across several listings | The seller does not physically hold the piece, so they cannot answer question 02 about it. |
| Payment only by wire, crypto or “friends and family” | Every one of those removes your recourse, which is exactly why it is being asked for. |
| A watch photographed with its serial number readable | Careless at best. Serial numbers get copied onto counterfeits, so a jeweler who knows the trade blurs them — we do. |
Each one is right for something. None is right for everything.
| Channel | Good for | What you carry yourself |
|---|---|---|
| Large marketplaces | Volume, low prices, and buyer-protection schemes on smaller sums. | All of the grading. Descriptions are written by sellers with no gemological training, and the platform does not check them. |
| Auction houses | Rare and important pieces, condition reports, and a paper trail. | A buyer’s premium on top of the hammer price, no negotiation, and lots sold as-is after a short viewing window. |
| Pawn and general resale | Occasionally sharp prices on plain gold. | Staff who buy by weight rather than by stone. Signed and gem-set pieces are regularly under-described, which cuts both ways. |
| Specialist estate dealer | Pieces already examined and documented, a named person answering the phone, and room to negotiate. | A smaller selection — one dealer holds only what one dealer found. |
There is no honest version of that table where one row wins outright. If you know exactly what you are looking at, a marketplace is a real opportunity. If you do not, you are paying a specialist to have looked — which is cheaper than paying for a stone that turns out to be something else.
Answering our own five questions, in order.
Every piece is examined in person by Arkadius Bizak — three decades in the Miami trade since 1996, gemmologically trained at HRD Antwerp (AWDC) and the ERIJ Foundation — before it goes online. If a piece is not what it appears to be, it does not get listed.
Purity, weights, condition and any signature are stated on the piece’s own page. Ask about anything the page does not cover and you get a straight answer, including when that answer is “we cannot prove that”.
Every piece ships with a certificate of authenticity and its gemological description, so what you were told is what you own. The detail is on our authenticity page.
Shipments travel by FedEx, fully insured under a jewelers policy through IFS, signature required on delivery. Nothing is sent uninsured, whatever the value.
Order through the form or on WhatsApp, and we confirm availability and send a secure payment link within one business day. Nothing is charged until you approve it.
Every piece has a “Make an Offer” button and we read the offers. If you are in Miami, pieces can be seen by private appointment in the Seybold Building.
Check it against the description, item by item. Weigh it if you have a scale, look for the hallmark where the seller said it was, count the stones. Do that while any recourse you negotiated is still open, not in six months.
Get an independent appraisal if you are insuring it. Insurers want a written retail replacement value from someone who is not the seller, and it is worth having a second trained pair of eyes on a piece you bought from a photograph. We write written appraisals for pieces bought anywhere, including from our competitors, and the fee is flat and quoted upfront.
Then look after it. Estate pieces have already survived decades, usually with worn prongs and a thinned shank to show for it. Ten minutes with the jewelry care guide will often save you the repair, and if something does need work, BizakAid handles mail-in repairs.
Yes, when the seller will put the details in writing. The risk is almost never a stolen payment — it is a vague description that turns out to be technically true. Ask who examined the piece and what their training is, what the metal purity and stone weights actually are, what documentation is included, how it ships and who insures it, and what happens if it is not as described. A dealer answers all five. Get those answers before you pay, not after.
Most estate diamonds have no lab report, and that is normal — reports became common long after these pieces were made. What matters is that whoever is selling it examined it and will state a colour and clarity range in writing. If you want independent confirmation, have it graded after purchase; a diamond can be identified and graded at any time. Our diamond buying guide covers what the four Cs actually change about the price.
If you are insuring the piece, yes — insurers want a written retail replacement value from an independent party, not the seller’s invoice. It is also the cleanest way to confirm that what arrived matches what was described. Appraisal fees are flat and quoted upfront, in line with the U.S. range of roughly $65 to $200 per piece depending on complexity.
At minimum, a written gemological description of what you bought. A certificate of authenticity from the seller if they authenticate their own stock — ours ships with one. A lab report if one exists for the centre stone, and box and papers for a watch if they survived. What no honest seller can hand you is a lab report for a piece that never had one, so treat a suspiciously complete paper trail with the same care as none at all.
It is, with the right carrier and the right policy. Our shipments go by FedEx, fully insured under a jewelers policy through IFS, signature required on delivery, and nothing leaves uninsured regardless of value. The mistake people make is sending high-value jewelry on a standard retail parcel service, where the declared-value cap is low and jewelry is frequently excluded outright.
Usually yes, and estate is one of the few corners of jewelry where that is still true, because there is no manufacturer’s list price to defend. Every piece on our site has a “Make an Offer” button and we read the offers. A reasonable offer on a piece that has been available a while does better than a low offer on something that has just arrived.
Because somebody else already paid the retail markup. A new piece carries the cost of the brand, the boutique and the box; once it has been owned, that premium is gone and what remains is the metal, the stones and the workmanship. On the same carat weight and the same quality of make, estate routinely costs a fraction of new — which is the whole argument for buying it.
