The math, in the open

How an offer is built.

Most buyers hand you one number and hope you don't ask. We show the two parts every honest offer is made of: what the metal is worth, and what the name adds. Pick an example.

14k gold chain
30g · unbranded · priced on metal content
Metal value 17.5g pure gold at live spot $1,490
Brand premium unbranded — no maker premium $0
Your offer up to $1,460

Illustrative example. Final offer is confirmed in person against live spot price and the actual piece. Plain gold is paid at melt — never below it. Branded and gem-set pieces are priced on the resale market, which is usually well above metal value.

Why our offer is higher

The same expertise. Less standing between you and the number.

/ 01

No chain to feed

National buyers carry twenty offices, sales floors and layers of staff — paid for out of your offer. We run lean and direct, so more of the real value reaches you.

/ 02

You see the breakdown

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.

/ 03

A gemologist, not a counter

HRD Antwerp and ERIJ credentialed. We read the cut, the maker and the market — which is exactly what separates a fair offer from a pawn-shop lowball.

The process

Four steps. No obligation, ever.

Request a shipping kit

Tell us what you have. We email a prepaid, fully-insured FedEx label and simple packing instructions — on our account, so you pay nothing.

Drop it at any FedEx

Pack it, then drop it at any FedEx location. Every shipment is fully insured and tracked door to door, with signature required at every step.

We value and send the offer

A credentialed gemologist examines each piece and emails a written offer with metal value and brand premium laid out separately.

Paid same day, or returned free

Accept any or all of it and you're paid the same day by bank transfer. Decline, and everything ships back to you — free and insured.

What we buy

If it's gold, signed or set, bring it.

Who you're selling to

A jewelry house, not a storefront that appeared this year.

Bizak & Co. has bought and sold fine jewelry and watches since 1996. The same trained eye that authenticates a stone for a buyer is the one that values what you mail in. That's the difference between an offer you can trust and a guess — even from across the country.

Before you ship

Questions, answered plainly.

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.

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.

The same day you accept 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.
