How selling with us works
Whether you are unwinding an estate, upgrading a collection, or simply prefer a clean exit, we purchase signed and unsigned pieces alike when the numbers make sense for both sides.
You may start with a secure digital review, visit our showroom at 204 N Federal Hwy in Deerfield Beach, or coordinate insured shipment after we align on preliminary expectations.

Frequently asked questions
How does Goldmine Exchange determine a purchase offer on fine jewelry or watches?
We weigh material value, brand demand, craftsmanship, condition, and comparable wholesale appetite. You receive the reasoning in conversational terms—not a black-box number.
Will you review unsigned or estate jewelry without a designer signature?
Yes. Many important pieces are unsigned or melt-adjacent. We still evaluate construction, stones, and period cues to see whether a strong secondary bid makes sense.
Do I need the original box and papers for a luxury watch?
They help but are not always mandatory. Serial clarity, service history, and dial or case integrity often matter as much; we tell you what closes the gap after your first photos.
May I walk away after an in-hand inspection if the offer does not suit me?
Yes—unless you have already accepted a binding written proposal you wish to honor. There is no pressure to say yes on the spot.
How soon can settlement occur after we agree on a price?
Timing depends on verification path and payment method, but we aim for an orderly, prompt close once terms are set. Your specialist gives a realistic calendar at acceptance.
Do you purchase loose diamonds or just mounted stones?
We review loose diamonds and mounted pieces alike, referencing grading when available and skilled observation when it is not.
