Each stone is priced differently — color, clarity standards, treatment and origin all work on their own scale. Start with the one you have.
Priced almost entirely on color, with Burmese origin and treatment history moving the number more than for almost any other gem.
Sell ruby jewelry by mail →Not just blue — pink, yellow, violet, green and padparadscha all have their own scale. One of the hardest, most durable gemstones.
Sell sapphire jewelry by mail →Visible inclusions (jardin) are normal, not a flaw. Clarity enhancement is standard practice — the degree is what matters.
Sell emerald jewelry by mail →This also covers rubies, sapphires and emeralds in any form — engagement rings, tennis bracelets, eternity bands, brooches, estate and inherited pieces, loose stones and mixed lots — plus less common colored stones such as tourmaline, aquamarine, tanzanite and spinel, evaluated case by case. Everything ships to us the same way: nationwide, by mail, on a free insured label.
Several factors move price independently of carat weight alone.
Mailing jewelry across the country only works if the shipment is genuinely covered — so every step of it is.
A few simple habits keep pieces from shifting, scratching or tangling in transit.

About pricing your gemstones
Get more than one opinion, and prefer a buyer who explains how they arrived at the number — separating metal value from stone value — rather than one who gives a single lump offer with no breakdown. A free, no-obligation appraisal lets you compare offers without any pressure to accept on the spot.
It depends on the buyer. Some price by melt value alone and treat any stone as incidental. Others evaluate the stone separately — by color, clarity, carat weight and origin — and add that value on top of the metal. Bizak & Co. shows both parts of the offer in writing, so you can see exactly what the stone added. Ask directly how a buyer prices colored stones before you send in a piece.
Yes. A lab report (GIA, AGL, HRD or similar) can speed up an appraisal because it removes uncertainty about treatment and origin, but it isn't required to get an offer. Send a photo first — by WhatsApp or the form on this page — and we'll tell you what we can already see and what we'd still need before making an offer.
Not automatically melted. Antique and estate pieces can carry value beyond their metal weight — from the maker, the era, the craftsmanship or the gemstone itself — that melting destroys permanently. A proper appraisal checks for that added value first; melting is only the right call when a piece genuinely has none beyond its metal content.
About mailing your jewelry safely
Yes. We email a prepaid, fully insured FedEx label — insurance is provided through IFS (In4Sure) for the full value of your pieces — tracked door to door with signature required at every handoff, both ways. You never arrange or pay for your own shipping or insurance.
You are covered, and it costs you nothing. Every shipment travels on our prepaid FedEx label backed by dedicated jewelry insurance (IFS / In4Sure) that covers the full value of your pieces — door to door, both directions, tracked, with signature required at every handoff. That is the same cover on the way back if you decline the offer.
No. Bizak & Co. is an established Miami jewelry house, founded in 1996, but the business is built for mail-in selling — we buy ruby, sapphire and emerald jewelry from sellers across the United States. You request a free insured shipping label, mail your piece from wherever you are, and never have to visit Miami.
You see the written offer before you decide anything, and payment goes out the same day you accept, by bank transfer. If you decline, there is no cost to you either — your jewelry ships back free and fully insured. Nothing is altered, disassembled or sold until you approve the offer in writing.
