Everything you might want to know before you buy — how to reserve a piece, how offers work, and how every piece is authenticated, insured, and delivered.
Bizak & Co. is a family house of estate jewelry and vintage watches in Miami's historic Seybold Building, in the trade since 1996. Below are the questions we hear most often. If yours isn't here, message us on WhatsApp — a real person answers.
Our collection is estate and vintage jewelry and pre-owned luxury watches — pieces with history, not mass-produced new stock. Each one is examined and authenticated by a trained gemologist before it is listed.
Yes. Almost every piece is a single, one-of-a-kind item. When it sells, it is gone — so if a piece speaks to you, it is worth reserving rather than waiting.
You can reserve a piece on its product page or over WhatsApp at (786) 907-8883. A secure payment link is sent only after your order is confirmed — never before.
Yes. Every product page has a Make an Offer option, or you can simply message us on WhatsApp. Many pieces are listed OBO — we are happy to talk.
Each piece ships in a Bizak & Co. presentation box, fully insured and signature-required, with its certificate of authenticity.
Because every piece is one of a kind and individually priced, sales are final — with one important exception: if a piece arrives that is not as described, you may return it. If the metal, stones, carat weights, signature, or condition differ materially from the listing, contact us as soon as it arrives and we will make it right with a full refund on return. It is the flip side of how we list — exact specifics, stated plainly, so what you receive is what you were promised.
Yes. Every piece is personally examined and authenticated by a trained gemologist before listing, and ships with a certificate of authenticity and its gemological description. Where a stone carries an independent laboratory report such as a GIA report, that report and its number are stated on the product page.
Absolutely. An appraisal is available on request, and you are always free to have any piece verified by an independent gemologist of your choosing. We list exact carat weights and specifics so there are no surprises.
A signed piece is described as signed, with its hallmark or maker's mark noted; an unsigned piece is described as unsigned. We never let a screw motif pass for a house it isn't — the signature, or its absence, is always stated plainly.
Message or call us on WhatsApp at (786) 907-8883, or request an appraisal through the site. We are based in Miami's historic Seybold Building, in the jewelry trade since 1996.
Ask about a specific piece — its stones, its papers, its maker — before you buy. We'd rather you be certain.
