Gold, estate jewelry and treasured pieces. What mattered then can make room for what matters now.
Sell jewelry ↗The math, in the open
Every offer we make has two parts, and we show you both: what the metal is worth, and what the name adds. Pick an example.
Illustrative example. Final offer is confirmed once your item arrives, against the live spot price that day and the actual piece. Plain gold is paid at 75% of melt value — the 25% covers refining and is shown on your offer. Branded and gem-set pieces are priced on the resale market, which is usually well above metal value.

Gold spot ≈ $4,170/oz · Indicative reference rate , not a live feed — gold moves daily. Your offer is confirmed against the live spot price the moment your piece arrives, so the final number can land above or below these figures. Branded, gem-set and estate pieces are worth well above melt — priced on the resale market, not weighed. Silver is quoted against live silver spot on the day your parcel arrives.
Quoted a price “per pennyweight” somewhere else? One pennyweight is 1.5552 grams, so it is not the same number as a price per gram. Grams, pennyweight and troy ounces, converted →
How we price plain gold
We weigh and test every piece, price it against the live spot price on the day it arrives, and pay 75% of melt value for plain gold — the 25% covers refining. The full number is in writing before you decide. Signed and gem-set pieces aren't weighed at all — they're priced on the resale market, which is usually well above melt.
Why sell to us
You deal with one family business in Miami's Seybold Building. The gemologist who values your piece is the one who makes you the offer.
Metal value and brand premium, separated and explained on paper. Nothing rolled into one mystery figure. If a number doesn't add up, you'll see it before you decide.
HRD Antwerp and ERIJ credentialed. We read the cut, the maker and the market, and price each piece on what it really is.

Your piece is safe
Your prepaid FedEx label carries dedicated jewelry cover through IFS Inforsure — a specialist jewelry-shipping insurer, not a carrier's flat default that stops at a token amount. Your pieces are insured for their full value on the way to us and on the way back, tracked door to door, with a signature required at every handoff.
A trained gemologist examines each piece and emails you a written offer. Until you accept it in writing, nothing is melted, altered, dismantled, or sold. Say no, and the exact pieces you sent come back to you — free and fully insured.
Because every shipment is insured to full value through IFS in both directions, a loss or damage in transit is covered for the full value your pieces are insured for — not a shipping minimum. Tracking and the required signature mean your jewelry is never left on a doorstep.
What we buy
Inherited collections, antique and designer pieces, every era. Valued piece by piece — the maker is part of the math, never blindly melted. This is what we most want to buy.
Rolex, Patek Philippe, Omega, Cartier, vintage Heuer and gold-cased pieces — priced on the resale market, never melted. Box and papers lift the number but are never required, and non-running watches are welcome.
Loose or set, certified or not. Read on the 4Cs and current demand by a trained gemologist.
Any karat, any condition — chains, rings, scrap, coins, dental. Weighed, tested and paid at 75% of melt value, priced the day we receive it.
Sterling flatware, hollowware, jewelry and scrap. Weighed and priced against the day's live silver spot.
Gold and silver coins, bars and rounds — bullion at melt, numismatic pieces read for collector premium.
Who you're selling to

Trained in gemology at HRD Antwerp (AWDC) and the ERIJ Foundation, he examines your gold, diamonds and watches piece by piece — so your offer reflects what your jewelry truly is, never a blind melt price.

Before you ship
Yes — fully. You ship on a prepaid FedEx label backed by dedicated jewelry insurance that covers the full value door to door, both ways, with signature required at every handoff. Your pieces are protected from the moment they leave your hands.
You owe nothing. We ship everything back to you free and fully insured. The valuation is free whether you sell or not — there's no fee for our time.
It gets examined and valued by a gemologist — that's all. Nothing is melted, altered, dismantled or sold until you accept the offer in writing. If you decline, the exact pieces you sent come back to you, free and insured. This matters most with signed and estate jewelry: melting a signed piece destroys value that can never be recovered, so we never make that call for you.
You're covered, and it costs you nothing. Every shipment travels on our prepaid FedEx label backed by dedicated jewelry insurance (IFS Inforsure) that covers the full value of your pieces — door to door, both directions, tracked, with signature required at every handoff. That's the same cover on the way back if you decline the offer. Tell us what you're sending when you request your kit, so the cover matches what's actually in the box.
Two parts, shown separately: the metal value at the day's live spot price, and a brand or gemstone premium based on maker, condition and current resale demand. You see both in writing before you decide anything.
Within 24 hours of accepting the offer, by bank transfer. No consignment, no waiting to find out what you'll get.
Not at all. They can increase the offer on certain watches and signed pieces, so include them if you have them — but we buy without them every day.
